libvirtError: virDomainLookupByName() failed

[hdevalence]

While using Qubes, I got a dom0 popup telling me "libvertError: virDomainLookupByName() failed", with the following log data:

----

I assume Qubes R3.1-rc1, right?

Q: Why is top-posting such a bad thing?

[hdevalence]

Yes, sorry for not specifying.

[marmarek]

Do you know any specific steps to reproduce this issue? Was it during starting some VM? Or maybe creating, stopping, launching some application? After restoring backup?

[hdevalence]

Nope, unfortunately I've been unable to reproduce it, so I'm afraid it's not a very helpful bug report :(

[marmarek]

Above logging finally caught this error. The error code is... None. Looks like a bug in libvirt library/python bindings.
