as one without the other does not make much sense with the current set
of modes.

update submodule and patches to QEMU 8.0.0 Many changes were necessary this time around: * QAPI was changed to avoid redundant has_* variables, see commit 44ea9d9be3 ("qapi: Start to elide redundant has_FOO in generated C") for details. This affected many QMP commands added by Proxmox too. * Pending querying for migration got split into two functions, one to estimate, one for exact value, see commit c8df4a7aef ("migration: Split save_live_pending() into state_pending_*") for details. Relevant for savevm-async and PBS dirty bitmap. * Some block (driver) functions got converted to coroutines, so the Proxmox block drivers needed to be adapted. * Alloc track auto-detaching during PBS live restore got broken by AioContext-related changes resulting in a deadlock. The current, hacky method was replaced by a simpler one. Stefan apparently ran into a problem with that when he wrote the driver, but there were improvements in the stream job code since then and I didn't manage to reproduce the issue. It's a separate patch "alloc-track: fix deadlock during drop" for now, you can find the details there. * Async snapshot-related changes: - The pending querying got adapted to the above-mentioned split and a patch is added to optimize it/make it more similar to what upstream code does. - Added initialization of the compression counters (for future-proofing). - It's necessary the hold the BQL (big QEMU lock = iothread mutex) during the setup phase, because block layer functions are used there and not doing so leads to racy, hard-to-debug crashes or hangs. It's necessary to change some upstream code too for this, a version of the patch "migration: for snapshots, hold the BQL during setup callbacks" is intended to be upstreamed. - Need to take the bdrv graph read lock before flushing. * hmp_info_balloon was moved to a different file. * Needed to include a new headers from time to time to still get the correct functions.
