[Pkg-libvirt-maintainers] Bug#566882: libvirtError: cannot create bridge 'virbr0': File exists

[Jonny Lamb]

Package: virt-manager
Version: 0.8.2-2
Severity: normal

I tried to create a network, but it failed with the following items
appearing in the log.

I guess the XML shows you what I was trying to do exactly.
