2023-04-24migration/postcopy: Detect file system on dest hostPeter Xu
Postcopy requires the memory support userfaultfd to work. Right now we check it but it's a bit too late (when switching to postcopy migration). Do that early right at enabling of postcopy. Note that this is still only a best effort because ramblocks can be dynamically created. We can add check in hostmem creations and fail if postcopy enabled, but maybe that's too aggressive. Still, we have chance to fail the most obvious where we know there's an existing unsupported ramblock.

2023-04-24migration: Handle block device inactivation failures betterEric Blake
Consider what happens when performing a migration between two host machines connected to an NFS server serving multiple block devices to the guest, when the NFS server becomes unavailable. The migration attempts to inactivate all block devices on the source (a necessary step before the destination can take over); but if the NFS server is non-responsive, the attempt to inactivate can itself fail. When that happens, the destination fails to get the migrated guest (good, because the source wasn't able to flush everything properly): (qemu) qemu-kvm: load of migration failed: Input/output error at which point, our only hope for the guest is for the source to take back control. With the current code base, the host outputs a message, but then appears to resume: (qemu) qemu-kvm: qemu_savevm_state_complete_precopy_non_iterable: bdrv_inactivate_all() failed (-1) (src qemu)info status VM status: running but a second migration attempt now asserts: (src qemu) qemu-kvm: ../block.c:6738: int bdrv_inactivate_recurse(BlockDriverState *): Assertion `!(bs->open_flags & BDRV_O_INACTIVE)' failed. Whether the guest is recoverable on the source after the first failure is debatable, but what we do not want is to have qemu itself fail due to an assertion. It looks like the problem is as follows: In migration.c:migration_completion(), the source sets 'inactivate' to true (since COLO is not enabled), then tries savevm.c:qemu_savevm_state_complete_precopy() with a request to inactivate block devices. In turn, this calls block.c:bdrv_inactivate_all(), which fails when flushing runs up against the non-responsive NFS server. With savevm failing, we are now left in a state where some, but not all, of the block devices have been inactivated; but migration_completion() then jumps to 'fail' rather than 'fail_invalidate' and skips an attempt to reclaim those those disks by calling bdrv_activate_all(). Even if we do attempt to reclaim disks, we aren't taking note of failure there, either. Thus, we have reached a state where the migration engine has forgotten all state about whether a block device is inactive, because we did not set s->block_inactive in enough places; so migration allows the source to reach vm_start() and resume execution, violating the block layer invariant that the guest CPUs should not be restarted while a device is inactive. Note that the code in migration.c:migrate_fd_cancel() will also try to reactivate all block devices if s->block_inactive was set, but because we failed to set that flag after the first failure, the source assumes it has reclaimed all devices, even though it still has remaining inactivated devices and does not try again. Normally, qmp_cont() will also try to reactivate all disks (or correctly fail if the disks are not reclaimable because NFS is not yet back up), but the auto-resumption of the source after a migration failure does not go through qmp_cont(). And because we have left the block layer in an inconsistent state with devices still inactivated, the later migration attempt is hitting the assertion failure. Since it is important to not resume the source with inactive disks, this patch marks s->block_inactive before attempting inactivation, rather than after succeeding, in order to prevent any vm_start() until it has successfully reactivated all devices.
