Choosing "run" from the menu results in this error sometimes. To run virt-manager I do "sudo virt-manager" since I can't seem to run it as my normal user.
Traceback (most recent call last):

Can you post /var/log/libvirt/qemu/<vmname>.log and ~/.virt-manager/virt-manager.log?
also, dcbw: see bug #524732 (polkit related) for what might be your "I can't seem to run it as my normal user" issue

Turns out this was the fstab devpts thing. Apparently at install time anaconda wasn't setting correct options (gid=5,mode=620) which caused this.
