Bug Description

Ubuntu 9.04 AMD64 Server edition
0.6.1-0ubuntu5

When running windows xp pro as a VM on qemu/kvm via dual cpu intel E5540 and issuing a command the command `virsh setvcpus winxp1 1` on a dual vcpu vm, I get the response "Connecting to uri: qemu:///system" which seems to last indefinitely. My VM becomes unresponsive and and that same message appears on all following virsh commands. Restarting /etc/init.d/libvirt-bin doesn't change it.

Confirmed on two Jaunty servers. (Guest is also Jaunty here)

There are two methods to recreate this:
- virsh setvcpus
- change vcpus with virt-manager (after pressing 'apply', virt-manager will become unresponsive too.)

Any chance of an updated version (debian testing/unstable is at 0.6.3-4) in karmic?

I have this problem too. Running `sudo invoke-rc.d libvirt-bin force-stop`, followed by `sudo invoke-rc.d libvirt-bin start` will get libvirtd working again.

Is there some workaround that we can use?
