 |
|
When internal snapshot created - it can be deleted without any issue, but when External snapshot created - any attempt to delete it gives permissions denied:
| Code: | Error deleting snapshot 'snapshot1': internal error: unable to execute QEMU command 'block-commit': Could not open '/var/lib/libvirt/images/gentoo.qcow2': Permission denied
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 71, in cb_wrapper
callback(asyncjob, *args, **kwargs)
~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 107, in tmpcb
callback(*args, **kwargs)
~~~~~~~~^^^^^^^^^^^^^^^^^
File "/usr/share/virt-manager/virtManager/object/domain.py", line 203, in delete

~~~~~~~~~~~~~~~~~~~~^^
File "/usr/lib/python3.13/site-packages/libvirt.py", line 7436, in delete
raise libvirtError('virDomainSnapshotDelete() failed')
libvirt.libvirtError: internal error: unable to execute QEMU command 'block-commit': Could not open '/var/lib/libvirt/images/gentoo.qcow2': Permission denied |
No matter what permissions on file - working user, libvirt, qemu, root... always same error.
Even changing permissions to 777 doesn't help.
$ virsh snapshot-delete gentoo snapshot1
error: Failed to delete snapshot snapshot1
error: internal error: unable to execute QEMU command 'block-commit': Could not open '/var/lib/libvirt/images/gentoo.snapshot1': Permission denied
same error when run with sudo
Please your help |

It seems apparmor is the issue, disabling it - allows snapshot to delete.
But no denied logs in audit.log, any idea how to allow snapshot delete via apparmor? |
