[libvirt-users] [BUG] Not exiting media forced a promptly close of libvirt 3.10

[Holger Schranz]

Hello,

In the .xml file I use a media which is no longer available.
In the past, I got the information media not available and the
creation of the VM was stopped - O.k. behavior.
Since 3.10 the libvirtd stopped promptly and all open
consoles windows and the virt-manager closed promptly.

For diagnose:
