What is the network configuration for the window XP box? How the network in
the host machine configured like how many NICs, and IP assignment to
vserver/ the kvm etc..

Instead of rebooting if your NIC driver is loaded as module, did you try to
unload/reload it and see if problem disappear?

I got some network problems before with stock kernel something
(from and with vserver patch) in some cases - esp. multiple
nics/networks gateway setup. I swtich to and no problem so far.

Did you see anything in the dmesg log? Something abt warn slow path in
networking stack?
