When deleting the VM, along with its file image, I am shown the
following error message in a pop-up.


`
Errors encountered while removing certain storage devices.

cannot unlink file '/var/lib/libvirt/images/debian8.qcow2': Success
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/delete.py", line 182, in _async_delete

    if ret == -1: raise libvirtError ('virStorageVolDelete() failed', vol=self)
libvirtError: cannot unlink file '/var/lib/libvirt/images/debian8.qcow2': Success


At one end, it says "Success" but also reports error.
Lookng at the datastore, the VM file is not deleted.

Hi,

The "Success" means that virFileRemove failed to set a proper errno.


Assuming your're using qemu:///system

Can you provide a bit of config information:

  virsh pool-dumpxml default
  virsh vol-dumpxml --pool  default debian8.qcow2

Can you also try to delete via vol-delete:

  virsh vol-delete --pool  default debian8.qcow2

That should fail as well. If it does please do a:

  grep libvirtd /var/log/syslog
  journalctl -u libvirtd.service

Cheers,
