Thanks for your help and replies. I'm a little bit lost on all these
comments. So what to check / do next?
Try with the deadline scheduler, and run "perf top" in guest/host if the
problems persist.
Right now i'm just starting to ping from the guest to a random domain.
it works for around 65s then i get the message:
ping: senmsg: No buffer space available
and the network connection is away until i reboot the guest.
