Virtual Machines existing before the update seem to function properly. It is only after creating a new machine that snapshots are misbehaving. I tested spinning up vms of tumbleweed, leap15, and ubuntu 18.04. Each of them had the following issues: - With the machine running, live reversions act like they apply, but no changes are actually made. - With the machine paused, reversion also does not apply. - With the machine turned off, reversion is not possible. Virsh is unable to find the snapshot, and virt-manager errors out with: Error running snapshot 'FreshInstall': internal error: qemu unexpectedly closed the monitor: 2019-01-15T19:19:46.020247Z qemu- system-x86_64: Device 'drive-virtio-disk0' does not have the requested snapshot 'FreshInstall' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 75, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 111, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 66, in newfn ret = fn(self, *args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1105, in revert_to_snapshot self._backend.revertToSnapshot(snap.get_backend()) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 2024, in revertToSnapshot if ret == -1: raise libvirtError ('virDomainRevertToSnapshot() failed', dom=self) libvirt.libvirtError: internal error: qemu unexpectedly closed the monitor: 2019-01-15T19:19:46.020247Z qemu-system-x86_64: Device 'drive-virtio-disk0' does not have the requested snapshot 'FreshInstall' After doing some digging, the error occurs because of the following commit: d98f26073bebddcd3da0ba1b86c3a34e840c0fb8 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1816189/+subscriptions
