+Subject: [PATCH] savevm-async: reuse migration blocker check for
+ snapshots/hibernation
+
+Same rationale as with upstream QEMU commit 5aaac46793 ("migration:
+savevm: consult migration blockers"), migration and (async) snapshot
+are essentially the same operation and thus snapshot also needs to
+check for migration blockers. For example, this catches passed-through
+PCI devices, where the driver does not support migration and VirtIO-GL
+display, which also does not support migration yet.
+
+In the case of VirtIO-GL, there were crashes [0].
+
+However, the commit notes:
+
+> There is really no difference between live migration and savevm, except
+> that savevm does not require bdrv_invalidate_cache to be implemented
+> by all disks.  However, it is unlikely that savevm is used with anything
+> except qcow2 disks, so the penalty is small and worth the improvement
+> in catching bad usage of savevm.
+
+and for Proxmox VE, suspend-to-disk with VMDK does use savevm-async
+and would be broken by simply using migration_is_blocked(). To keep
+this working, introduce a new helper that filters blockers with the
+prefix used by the VMDK migration blocker.
+
+The function qemu_savevm_state_blocked() is called as part of
+savevm_async_is_blocked() so no check is lost with this
+patch. The helper is declared in migration/migration.c to be able to
+access the 'migration_blockers'.
+
+The VMDK blocker message is declared via a '#define', because using a
+'const char*' led to the linker to complain about multiple
+declarations. The message does not include the reference to the block
+node anymore, but users can still easily find a VMDK disk in the VM
+configuration.
+
+Note, this also "breaks" snapshot and hibernate with VNC clipboard by
+preventing it. Previously, this would "work", because the Proxmox VE
+API has no check yet, but the clipboard will be broken after rollback,
+in the sense that it cannot be used anymore, not just lost contents.
+So some users might consider adding the check here a breaking change
+even if it's technically correct to prevent snapshot and hibernate
+with VNC clipboard. But other users might rightfully complain about
+broken clipboard. And again, the check also prevents blockers from
+passed-through PCI devices, etc. so it seems worth tolerating that
+breakage.
