I tried changing the switch, but sadly this didn't solve the issue. 
I'm still not totally sure it's Xen related. Another VM, the firewall, running 
on the same interface where I have problems, doesn't seem to suffer the same, 
on this subnet. Instead, I'm having issues on another interface, the one facing 
the router, because I get OpenVPN reset every minute.

Both VMs have very low cpu and network load according to stats, so I'd exclude 
performance problems. 

Any advice is welcome!
thanks
