[Bug 1481295] Re: virt-manager after upgrade: Error polling connection 'qemu:///system': internal error: could not get interface XML description: File operation failed - Failed to read (null)

[Fernando Fernandez]

I thought this was resolved with some update, since it started working
some weeks ago. But from these comments I understand that it isn't. :-)

I remembered that I used to have an eth0:1 interface and just tried it
again. The problem returns when the interface eth0:1 is up.

The ifconfig -a output is:
