I've seen this behaviior with VMware and Xen also as well as KVM.  One level of
virtualization works fine but two levels of virtualizing the display and the
mouse appears to be a bit much for the current level of the technology and it
doesn't seem to matter which virtualization platform you use.

The Arun's response is probably your best bet for acceptable behavior.  You just
need to make the network interface for the VM as visible as your desktop's.
