Comment 3 for bug 1251521

Nevermind, I don't think this is bug 1257644 (which is actually a dupe of bug 1255624), this has it's own signature. 5 hits in the last 2 weeks on this one:

message:"libvirtError: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Connection refused'" AND filename:"logs/screen-n-cpu.txt"

Interestingly they only show up in the check queue, but that probably doesn't matter.
