[Xen-users] a lot of packet loss

[Attila Szamos <szamosa@xxxxxxxxx>]

I've fix-ed the timesyncronization problem. But I don't know where to
start with the network problem.
If I ping the VM a lot of packet didn't get an echo reply.

I've tried to switch the networking to 'route' from 'bridge', but it
didn't help. Any suggestions?
