* revert a commit for VirtIO PCI devices that turned out to cause more
|
||||
potential security issues than what it fixed
|
||||
|
||||
* move compatibility flags for a new VirtIO-net feature to the correct
|
||||
machine type. The feature was introduced in QEMU 8.2, but the
|
||||
compatibility flags got added to machine version 8.0 instead of 8.1. This
|
||||
breaks backwards migration with machine version 8.1 from a 8.2/9.0 binary
|
||||
to an 8.1 binary, in cases where the guest kernel enables the feature
|
||||
(e.g. Ubuntu 23.10).
|
||||
While that breaks migration with machine version 8.1 from an unpatched to
|
||||
a patched binary, Proxmox VE only ever had 8.2 on the test repository and
|
||||
9.0 not yet in any public repository.

Subject: [PATCH] ide: avoid potential deadlock when draining during trim
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The deadlock can happen as follows:
|
||||
1. ide_issue_trim is called, and increments the in_flight counter.
|
||||
2. ide_issue_trim_cb calls blk_aio_pdiscard.
|
||||
3. Somebody else starts draining (e.g. backup to insert the cbw node).
|
||||
4. ide_issue_trim_cb is called as the completion callback for
|
||||
blk_aio_pdiscard.
|
||||
5. ide_issue_trim_cb issues yet another blk_aio_pdiscard request.
|
||||
6. The request is added to the wait queue via blk_wait_while_drained,
|
||||
because draining has been started.
|
||||
7. Nobody ever decrements the in_flight counter and draining can't
|
||||
finish. This would be done by ide_trim_bh_cb, which is called after
|
||||
ide_issue_trim_cb has issued its last request, but
|
||||
ide_issue_trim_cb is not called anymore, because it's the
|
||||
completion callback of blk_aio_pdiscard, which waits on draining.
|
||||
|
||||
Quoting Hanna Czenczek:
|
||||
> The point of 7e5cdb345f was that we need any in-flight count to
|
||||
> accompany a set s->bus->dma->aiocb. While blk_aio_pdiscard() is
|
||||
> happening, we don’t necessarily need another count. But we do need
|
||||
> it while there is no blk_aio_pdiscard().
|
||||
> ide_issue_trim_cb() returns in two cases (and, recursively through
|
||||
> its callers, leaves s->bus->dma->aiocb set):
|
||||
> 1. After calling blk_aio_pdiscard(), which will keep an in-flight
|
||||
> count,
|
||||
> 2. After calling replay_bh_schedule_event() (i.e.
|
||||
> qemu_bh_schedule()), which does not keep an in-flight count.
|
||||
|
||||
Thus, even after moving the blk_inc_in_flight to above the
|
||||
replay_bh_schedule_event call, the invariant "ide_issue_trim_cb
|
||||
returns with an accompanying in-flight count" is still satisfied.
|
||||
|
||||
However, the issue 7e5cdb345f fixed for canceling resurfaces, because
|
||||
ide_cancel_dma_sync assumes that it just needs to drain once. But now
|
||||
the in_flight count is not consistently > 0 during the trim operation.
|
||||
So, change it to drain until !s->bus->dma->aiocb, which means that the
|
||||
operation finished (s->bus->dma->aiocb is cleared by ide_set_inactive
|
||||
via the ide_dma_cb when the end of the transfer is reached).
|
||||

||||

Subject: [PATCH] monitor/hmp: add support for flag argument with value
|
||||
|
||||
Adds support for the "-xS" parameter type, where "-x" denotes a flag
|
||||
name and the "S" suffix indicates that this flag is supposed to take an
|
||||
arbitrary string parameter.
|
||||
|
||||
These parameters are always optional, the entry in the qdict will be
|
||||
omitted if the flag is not given.

Content-Type: text/plain; charset=UTF-8

It is possible to specify more than one VNC server on the command line,
|
||||
either with an explicit ID or the auto-generated ones à la "default",
|
||||
"vnc2", "vnc3", ...
|
||||
|
||||
It is not possible to change the password on one of these extra VNC
|
||||
displays though. Fix this by adding a "display" parameter to the
|
||||
"set_password" and "expire_password" QMP and HMP commands.
|
||||
|
||||
For HMP, the display is specified using the "-d" value flag.
|
||||
|
||||
For QMP, the schema is updated to explicitly express the supported
|
||||
variants of the commands with protocol-discriminated unions.

Content-Transfer-Encoding: 8bit

When allocating new temps during tcg_optmize, do not re-use
|
||||
any EBB temps that were used within the TB. We do not have
|
||||
any idea what span of the TB in which the temp was live.
|
||||
|
||||
Introduce tcg_temp_ebb_reset_freed and use before tcg_optimize,
|
||||
as well as replacing the equivalent in plugin_gen_inject and
|
||||
tcg_func_start.

In mirror_iteration() we call mirror_wait_on_conflicts() with

`self` parameter set to NULL.

Starting from commit d44dae1a7c we dereference `self` pointer in

mirror_wait_on_conflicts() without checks if it is not NULL.

Subject: [PATCH] target/i386: Reset TSCs of parked vCPUs too on VM reset
|
||||
|
||||
Since commit 5286c3662294 ("target/i386: properly reset TSC on reset")
|
||||
QEMU writes the special value of "1" to each online vCPU TSC on VM reset
|
||||
to reset it.
|
||||
|
||||
However parked vCPUs don't get that handling and due to that their TSCs
|
||||
get desynchronized when the VM gets reset.
|
||||
This in turn causes KVM to turn off PVCLOCK_TSC_STABLE_BIT in its exported
|
||||
PV clock.
|
||||
Note that KVM has no understanding of vCPU being currently parked.
|
||||
|
||||
Without PVCLOCK_TSC_STABLE_BIT the sched clock is marked unstable in
|
||||
the guest's kvm_sched_clock_init().
|
||||
This causes a performance regressions to show in some tests.
|
||||
|
||||
Fix this issue by writing the special value of "1" also to TSCs of parked
|
||||
vCPUs on VM reset.
|
||||
|
||||
Reproducing the issue:
|
||||
1) Boot a VM with "-smp 2,maxcpus=3" or similar
|
||||
|
||||
2) device_add host-x86_64-cpu,id=vcpu,node-id=0,socket-id=0,core-id=2,thread-id=0
|
||||
|
||||
3) Wait a few seconds
|
||||
|
||||
4) device_del vcpu
|
||||
|
||||
5) Inside the VM run:
|
||||
# echo "t" >/proc/sysrq-trigger; dmesg | grep sched_clock_stable
|
||||
Observe the sched_clock_stable() value is 1.
|
||||
|
||||
6) Reboot the VM
|
||||
|
||||
7) Once the VM boots once again run inside it:
|
||||
# echo "t" >/proc/sysrq-trigger; dmesg | grep sched_clock_stable
|
||||
Observe the sched_clock_stable() value is now 0.

Subject: [PATCH] net: Fix announce_self
|
||||
|
||||
b9ad513e1876 ("net: Remove receive_raw()") adds an iovec entry
|
||||
in qemu_deliver_packet_iov() to add the virtio-net header
|
||||
in the data when QEMU_NET_PACKET_FLAG_RAW is set but forgets
|
||||
to increase the number of iovec entries in the array, so
|
||||
receive_iov() will only send the first entry (the virtio-net
|
||||
entry, full of 0) and no data. The packet will be discarded.
|
||||
|
||||
The only user of QEMU_NET_PACKET_FLAG_RAW is announce_self.
|
||||
|
||||
We can see the problem with tcpdump:
|

Subject: [PATCH] pci: acpi: Windows 'PCI Label Id' bug workaround
|
||||
|
||||
Current versions of Windows call _DSM(func=7) regardless
|
||||
of whether it is supported or not. It leads to NICs having bogus
|
||||
'PCI Label Id = 0', where none should be set at all.
|
||||
|
||||
Also presence of 'PCI Label Id' triggers another Windows bug
|
||||
on localized versions that leads to hangs. The later bug is fixed
|
||||
in latest updates for 'Windows Server' but not in consumer
|
||||
versions of Windows (and there is no plans to fix it
|
||||
as far as I'm aware).
|
||||
|
||||
Given it's easy, implement Microsoft suggested workaround
|
||||
(return invalid Package) so that affected Windows versions
|
||||
could boot on QEMU.
|
||||
This would effectvely remove bogus 'PCI Label Id's on NICs,
|
||||
but MS teem confirmed that flipping 'PCI Label Id' should not
|
||||
change 'Network Connection' ennumeration, so it should be safe
|
||||
for QEMU to change _DSM without any compat code.
|
||||
|
||||
Smoke tested with WinXP and WS2022

Subject: [PATCH] hw/usb/hcd-xhci-pci: Use modulo to select MSI vector as per
|
||||
spec
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit
|
||||
|
||||
QEMU would crash with a failed assertion if the XHCI controller
|
||||
attempted to raise the interrupt on an interrupter corresponding
|
||||
to a MSI vector with a higher index than the highest configured
|
||||
for the device by the guest driver.
|
||||
|
||||
This behaviour is correct on the MSI/PCI side: per PCI 3.0 spec,
|
||||
devices must ensure they do not send MSI notifications for
|
||||
vectors beyond the range of those allocated by the system/driver
|
||||
software. Unlike MSI-X, there is no generic way for handling
|
||||
aliasing in the case of fewer allocated vectors than requested,
|
||||
so the specifics are up to device implementors. (Section
|
||||
6.8.3.4. "Sending Messages")
|
||||
|
||||
It turns out the XHCI spec (Implementation Note in section 4.17,
|
||||
"Interrupters") requires that the host controller signal the MSI
|
||||
vector with the number computed by taking the interrupter number
|
||||
modulo the number of enabled MSI vectors.
|
||||
|
||||
This change introduces that modulo calculation, fixing the
|
||||
failed assertion. This makes the device work correctly in MSI mode
|
||||
with macOS's XHCI driver, which only allocates a single vector.

Subject: [PATCH] pci: ensure valid link status bits for downstream ports
|
||||
|
||||
PCI hotplug for downstream endpoints on arm fails because Linux'
|
||||
PCIe hotplug driver doesn't like the QEMU provided LNKSTA:
|
||||
|
||||
pcieport 0000:08:01.0: pciehp: Slot(2): Card present
|
||||
pcieport 0000:08:01.0: pciehp: Slot(2): Link Up
|
||||
pcieport 0000:08:01.0: pciehp: Slot(2): Cannot train link: status 0x2000
|
||||
|
||||
There's 2 cases where LNKSTA isn't setup properly:
|
||||
* the downstream device has no express capability
|
||||
* max link width of the bridge is 0
|
||||
|
||||
Move the sanity checks added via 88c869198aa63
|
||||
("pci: Sanity test minimum downstream LNKSTA") outside of the
|
||||
branch to make sure downstream ports always have a valid LNKSTA.

Subject: [PATCH] PVE: add IOChannel implementation for savevm-async
|
||||
|
||||
based on migration/channel-block.c and the implementation that was
|
||||
present in migration/savevm-async.c before QEMU 7.1.
|
||||
|
||||
Passes along read/write requests to the given BlockBackend, while
|
||||
ensuring that a read request going beyond the end results in a
|
||||
graceful short read.
|
||||
|
||||
Additionally, allows tracking the current position from the outside
|
||||
(intended to be used for progress tracking).

Subject: [PATCH] PVE-Backup: add vma backup format code
|
||||
|
||||
Notes about partial restoring: skipping a certain drive is done via a

||||
map line of the form skip=drive-scsi0. Since in PVE, most archives are
|
||||
compressed and piped to vma for restore, it's not easily possible to
|

skip reads.

Subject: [PATCH] block/backup: move bcs bitmap initialization to job creation
|
||||
|
||||
For backing up the state of multiple disks from the same time, a job
|
||||
for each disk has to be created. It's convenient if the jobs don't
|
||||
have to be started at the same time and if operation of the VM can be
|
||||
resumed after job creation. This would lead to a window between job
|
||||
creation and running the job, where writes can happen. But no writes
|
||||
should happen between setting up the copy-before-write filter and
|
||||
setting up the block copy state bitmap, because then new writes would
|
||||
just pass through.
|
||||
|
||||
Commit 06e0a9c16405c0a4c1eca33cf286cc04c42066a2 moved initalization of
|
||||
the bitmap to setting up the copy-before-write filter when sync_mode
|
||||
is not MIRROR_SYNC_MODE_BITMAP. Ensure that the bitmap is initialized
|
||||
upon job creation for the remaining case too, by moving the
|
||||
backup_init_bcs_bitmap call to backup_job_create.

|

Subject: [PATCH] PVE-Backup: Add dirty-bitmap tracking for incremental backups
|
||||
|
||||
Uses QEMU's existing MIRROR_SYNC_MODE_BITMAP and a dirty-bitmap on top
|
||||
of all backed-up drives. This will only execute the data-write callback
|
||||
for any changed chunks, the PBS rust code will reuse chunks from the
|
||||
previous index for everything it doesn't receive if reuse_index is true.
|
||||
|
||||
On error or cancellation, remove all dirty bitmaps to ensure
|
||||
consistency.
|
||||
|
||||
Add PBS/incremental specific information to query backup info QMP and
|
||||
HMP commands.
|
||||
|
||||
Only supported for PBS backups.

|

Subject: [PATCH] PVE-Backup: Use a transaction to synchronize job states
|
||||
|
||||
By using a JobTxn, we can sync dirty bitmaps only when *all* jobs were
|
||||
successful - meaning we don't need to remove them when the backup fails,
|
||||
since QEMU's BITMAP_SYNC_MODE_ON_SUCCESS will now handle that for us.
|
||||
|
||||
To keep the rate-limiting and IO impact from before, we use a sequential
|
||||
transaction, so drives will still be backed up one after the other.

|
||||
Subject: [PATCH] PVE-Backup: Don't block on finishing and cleanup
|
||||
create_backup_jobs
|
||||
|
||||
proxmox_backup_co_finish is already async, but previously we would wait
|
||||
for the coroutine using block_on_coroutine_fn(). Avoid this by
|
||||
scheduling pvebackup_co_complete_stream (and thus pvebackup_co_cleanup)
|
||||
as a real coroutine when calling from pvebackup_complete_cb. This is ok,
|
||||
since complete_stream uses the backup_mutex internally to synchronize,
|
||||
and other streams can happily continue writing in the meantime anyway.
|
||||
|
||||
To accomodate, backup_mutex is converted to a CoMutex. This means
|
||||
converting every user to a coroutine. This is not just useful here, but
|
||||
will come in handy once this series[0] is merged, and QMP calls can be
|
||||
yield-able coroutines too. Then we can also finally get rid of
|
||||
block_on_coroutine_fn.
|
||||
|
||||
Cases of aio_context_acquire/release from within what is now a coroutine
|
||||
are changed to aio_co_reschedule_self, which works since a running
|
||||
coroutine always holds the aio lock for the context it is running in.
|
||||
|
||||
job_cancel_sync is called from a BH since it can't be run from a
|
||||
coroutine (uses AIO_WAIT_WHILE internally).
|
||||
|
||||
Same thing for create_backup_jobs, which is converted to a BH too.
|
||||
|
||||
To communicate the finishing state, a new property is introduced to
|
||||
query-backup: 'finishing'. A new state is explicitly not used, since
|
||||
that would break compatibility with older qemu-server versions.
|
||||
|
||||
Also fix create_backup_jobs:
|
||||
|
||||
No more weird bool returns, just the standard "errp" format used
|
||||
everywhere else too. With this, if backup_job_create fails, the error
|
||||
message is actually returned over QMP and can be shown to the user.
|
||||
|
||||
To facilitate correct cleanup on such an error, we call
|
||||
create_backup_jobs as a bottom half directly from pvebackup_co_prepare.
|
||||
This additionally allows us to actually hold the backup_mutex during
|
||||
operation.
|
||||
|
||||
Also add a job_cancel_sync before job_unref, since a job must be in
|
||||
STATUS_NULL to be deleted by unref, which could trigger an assert
|
||||
before.

Subject: [PATCH] PVE: Use coroutine QMP for backup/cancel_backup
|
||||
|
||||
Finally turn backup QMP calls into coroutines, now that it's possible.
|
||||
This has the benefit that calls are asynchronous to the main loop, i.e.
|
||||
long running operations like connecting to a PBS server will no longer
|
||||
hang the VM.
|
||||
|
||||
Additionally, it allows us to get rid of block_on_coroutine_fn, which
|
||||
was always a hacky workaround.
|
||||
|
||||
While we're already spring cleaning, also remove the QmpBackupTask
|
||||
struct, since we can now put the 'prepare' function directly into
|
||||
qmp_backup and thus no longer need those giant walls of text.
|
||||
|
||||
(Note that for our patches to work with 5.2.0 this change is actually
|
||||
required, otherwise monitor_get_fd() fails as we're not in a QMP
|
||||
coroutine, but one we start ourselves - we could of course set the
|
||||
monitor for that coroutine ourselves, but let's just fix it the right
|
||||
way instead)

From: Fabian Ebner <f.ebner@proxmox.com>

Date: Tue, 17 May 2022 09:46:02 +0200
|
||||
Subject: [PATCH] Revert "block/rbd: implement bdrv_co_block_status"
|
||||
|
||||
During backup, bdrv_co_block_status is called for each block copy
|
||||
chunk. When RBD is used, the current implementation with
|
||||
rbd_diff_iterate2() using whole_object=true takes about linearly more
|
||||
time, depending on the image size. Since there are linearly more
|
||||
chunks, the slowdown is quadratic, becoming unacceptable for large
|
||||
images (starting somewhere between 500-1000 GiB in my testing).
|
||||
|
||||
This reverts commit 0347a8fd4c3faaedf119be04c197804be40a384b as a
|
||||
stop-gap measure, until it's clear how to make the implemenation
|
||||
more efficient.

Subject: [PATCH] alloc-track: error out when auto-remove is not set
|

|
||||
Since replacing the node now happens in the stream job, where the
|
||||
option cannot be read from (it's internal to the driver), it will
|
||||
always be treated as on.
|
||||
|
||||
qemu-server will always set it, make sure to have other users notice
|
||||
the change (should they even exist). The option can be fully dropped
|
||||
in the future while adding a version guard in qemu-server.

Subject: [PATCH] alloc-track: avoid seemingly superfluous child permission
|
||||
update
|
||||
|
||||
Doesn't seem necessary nowadays (maybe after commit "alloc-track: fix
|
||||
deadlock during drop" where the dropping is not rescheduled and delayed
|
||||
anymore or some upstream change). Should there really be some issue,
|
||||
instead of having a drop state, this could also be just based off the
|
||||
fact whether there is still a backing child.
|
||||
|
||||
Dumping the cumulative (shared) permissions for the BDS with a debug
|
||||
print yields the same values after this patch and with QEMU 8.1,
|
||||
namely 3 and 5.

Subject: [PATCH] PVE backup: add fleecing option
|
||||
|
||||
When a fleecing option is given, it is expected that each device has
|
||||
a corresponding "-fleecing" block device already attached, except for
|
||||
EFI disk and TPM state, where fleecing is never used.
|
||||
|
||||
The following graph was adapted from [0] which also contains more
|
||||
details about fleecing.
|
||||
|
||||
[guest]
|
||||
|
|
||||
| root
|
||||
v file
|
||||
[copy-before-write]<------[snapshot-access]
|
||||
| |
|
||||
| file | target
|
||||
v v
|
||||
[source] [fleecing]
|
||||
|
||||
For fleecing, a copy-before-write filter is inserted on top of the
|
||||
source node, as well as a snapshot-access node pointing to the filter
|
||||
node which allows to read the consistent state of the image at the
|
||||
time it was inserted. New guest writes are passed through the
|
||||
copy-before-write filter which will first copy over old data to the
|
||||
fleecing image in case that old data is still needed by the
|
||||
snapshot-access node.
|
||||
|
||||
The backup process will sequentially read from the snapshot access,
|
||||
which has a bitmap and knows whether to read from the original image
|
||||
or the fleecing image to get the "snapshot" state, i.e. data from the
|
||||
source image at the time when the copy-before-write filter was
|
||||
inserted. After reading, the copied sections are discarded from the
|
||||
fleecing image to reduce space usage.
|
||||
|
||||
All of this can be restricted by an initial dirty bitmap to parts of
|
||||
the source image that are required for an incremental backup.
|
||||
|
||||
For discard to work, it is necessary that the fleecing image does not
|
||||
have a larger cluster size than the backup job granularity. Since
|
||||
querying that size does not always work, e.g. for RBD with krbd, the
|
||||
cluster size will not be reported, a minimum of 4 MiB is used. A job
|
||||
with PBS target already has at least this granularity, so it's just
|
||||
relevant for other targets. I.e. edge cases where this minimum is not
|
||||
enough should be very rare in practice. If ever necessary in the
|
||||
future, can still add a passed-in value for the backup QMP command to
|
||||
override.
|
||||
|
||||
Additionally, the cbw-timeout and on-cbw-error=break-snapshot options
|
||||
are set when installing the copy-before-write filter and
|
||||
snapshot-access. When an error or timeout occurs, the problematic (and
|
||||
each further) snapshot operation will fail and thus cancel the backup
|
||||
instead of breaking the guest write.
|
||||
|
||||
Note that job_id cannot be inferred from the snapshot-access bs because
|
||||
it has no parent, so just pass the one from the original bs.

Subject: [PATCH] PVE backup: improve error when copy-before-write fails for
|
||||
fleecing
|
||||
|
||||
With fleecing, failure for copy-before-write does not fail the guest
|
||||
write, but only sets the snapshot error that is associated to the
|
||||
copy-before-write filter, making further requests to the snapshot
|
||||
access fail with EACCES, which then also fails the job. But that error
|
||||
code is not the root cause of why the backup failed, so bubble up the
|
||||
original snapshot error instead.

Subject: [PATCH] block/io: accept NULL qiov in bdrv_pad_request
|
||||
|
||||
Some operations, e.g. block-stream, perform reads while discarding the
|
||||
results (only copy-on-read matters). In this case they will pass NULL as
|
||||
the target QEMUIOVector, which will however trip bdrv_pad_request, since
|
||||
it wants to extend its passed vector.
|
||||
|
||||
Simply check for NULL and do nothing, there's no reason to pad the
|
||||
target if it will be discarded anyway.

Subject: [PATCH] PVE backup: fixup error handling for fleecing
|
||||
|
||||
The drained section needs to be terminated before breaking out of the
|
||||
loop in the error scenarios. Otherwise, guest IO on the drive would
|
||||
become stuck.
|
||||
|
||||
If the job is created successfully, then the job completion callback
|
||||
will clean up the snapshot access block nodes. In case failure
|
||||
happened before the job is created, there was no cleanup for the
|
||||
snapshot access block nodes yet. Add it.

This only worked if the target supports backing images, so up until now

only for qcow2, with alloc-track any driver for the target can be used.
|

|
||||
Replacing the node cannot be done in the
|

track_co_change_backing_file() callback, because replacing a node
|
||||
cannot happen in a coroutine and requires the block graph lock

exclusively. Could either become a special option for the stream job,

or maybe the upcoming blockdev-replace QMP command can be used in the

future.

If 'auto-remove' is set, alloc-track will automatically detach itself

once the backing image is removed. It will be replaced by 'file'.

Subject: [PATCH] PVE backup: factor out setting up snapshot access for
|
||||
fleecing
|
||||
|
||||
Avoids some line bloat in the create_backup_jobs_bh() function and is
|
||||
in preparation for setting up the snapshot access independently of
|
||||
fleecing, in particular that will be useful for providing access to
|
||||
the snapshot via NBD.

Subject: [PATCH] PVE backup: save device name in device info structure
|
||||
|
||||
The device name needs to be queried while holding the graph read lock
|
||||
and since it doesn't change during the whole operation, just get it
|
||||
once during setup and avoid the need to query it again in different
|
||||
places.
|
||||
|
||||
Also in preparation to use it more often in error messages and for the
|
||||
upcoming external backup access API.

Subject: [PATCH] adapt machine version deprecation for Proxmox VE
|
||||
|
||||
In commit a35f8577a0 ("include/hw: add macros for deprecation &
|
||||
removal of versioned machines"), a new machine version deprecation and
|
||||
removal policy was introduced. After only 3 years a machine version
|
||||
will be deprecated while being removed after 6 years.
|
||||
|
||||
The deprecation is a bit early considering major PVE releases are
|
||||
approximately every 2 years. This means that a deprecation warning can
|
||||
already happen for a machine version that was introduced during the
|
||||
previous major release. This would scare users for no good reason, so
|
||||
avoid deprecating machine versions in PVE too early and define a
|
||||
baseline of machine versions that will be supported throughout a
|
||||
single major PVE release.
