[Xen-users] cannot ping after xen install

[Zoran Kikic <lists@xxxxxxxxxx>]

I installed 3.2 on a Ubuntu gutsy (7.10 / AMD64) server and everything
looks fine. Xen booting up without errors or warnings but ping fails
when I try to ping a machine in my network. 8 pings are OK but the ninth
hangs for about 3000ms, the next 8 or 10 pings are normal and so on..
The dom0 itself is in that time not pingable from network. Well, that's
not all... I just have to wait long enough (about 10 min.) and sometimes
a miracle happen and everything works...
