Anyway, since the problem occurs with libvirt, have you already tried to report this issue to the libvirt project instead? ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1816189 Title: Unable to create or revert snapshots Status in QEMU: Incomplete Bug description: With an update to Qemu (3.1.x) I am unable to revert snapshots using virt-manager or virsh. 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 c= hanges 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 tm= pcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 66, i= n newfn ret =3D fn(self, *args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1105, in rev= ert_to_snapshot self._backend.revertToSnapshot(snap.get_backend()) File "/usr/lib64/python3.6/site-packages/libvirt.py", line 2024, in rev= ertToSnapshot if ret =3D=3D -1: raise libvirtError ('virDomainRevertToSnapshot() fa= iled', dom=3Dself) 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 commi= t: d98f26073bebddcd3da0ba1b86c3a34e840c0fb8 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1816189/+subscriptions
