[virt-tools-list] Error reporting

[Mirko Galimberti]

Tomorrow i will try to backtrace.
If can help,when i try to connect via "virsh -c virtualmachinename" i have 2 errors:
"error: failed to connect to the hypervisor"
"error: no connection driver available for virtualmachinename"

But "virsh -c qemu:///system list" is working fine.

I'm on ubuntu 14.04 64bit LTS

That usually means libvirt has crashed. So try to catch the libvirt backtrace
and file a bug with your distribution.

Never seen that before, could be a virt-manager threading issue or a gtk
issue, tough to say. I'd recommend filing a bug with your distro and let them
help debug it.
