Nothing seems to change. Indeed, also pinging the guest has the same 
problems. I'm also monitoring this machine since this morning and 
services are up and down and I can not understand why.

iptables on dom0 and vm guest are, at the moment, turned off.


1. This happens on all XEN guests on this physical server, except dom0. 
It does not happen on any other server/xen guest.

2. Outgoing network connections are fine.

3. xm console <xen_guest> works fine.
