New subject: [PATCH 01/17] qemuProcessStartWithMemoryState: Don't setup qemu for incoming migration when reverting internal snapshot

From: Peter Krempa <pkrempa(a)redhat.com> The memory/device state of the VM for an internal snapshot is restored by qemu itself via a QMP command and is taken from the qcow2 image, thus we don't actually do any form of incoming migration. Commit 5b324c0a739fe00 which refactored the setup of the incoming migration state didn't take the above into account and inadvertently caused that qemu is being started with '-incoming defer' also when libvirt would want to revert an internal snapshot. Now when qemu expects incoming migration it doesn't activate the block backends as that would cause locking problems and image inconsistency, but also doesn't allow the use of the images. Since the block backends are not activated qemu then thinks that they don't actually support internal snapshots and reports: error: operation failed: load of internal snapshot 'foo1' job failed: Device 'libvirt-1-format' is writable but does not support snapshots Due to the above bug it's not possible to revert to internal snapshots in libvirt-11.2 and libvirt-11.3.

New subject: [PATCH 03/17] qemuSnapshotRevertActive: Remove transient domain on failure

From: Peter Krempa <pkrempa(a)redhat.com> Code paths which deal with stopping of the qemu process need extra handling for transient definitions as they need to be removed from the domain list when we'd be leaving them inactive. In case of snapshot code it's on failure to revert a snapshot as we stop the qemu process but the failure to revert may mean that the new process will not be started.
