The root cause is this qemu bug: https://bugzilla.redhat.com/show_bug.cgi?id=724814 However I've pushed an updated python-virtinst build that will at least catch this error so that you can 'open' the connection and have a better chance of finding out what's wrong (the new VM wizard will give some more info) But basically until that above bug is fixed you can't do a whole lot with the connection.

It may not be a software problem at all. As per http://barryp.org/blog/entries/make-sure-virtualization-enabled-bios/, make sure virtualization is enabled in the BIOS. I had this problem on a new system and it went away when I did.
