Comment 14 for bug 579276

Please note that this bug eventually kills my VM. It loses network, logs nfs timeouts and won't let anyone login to the console, nor do anything useful. A reboot of the guest fixes this, but since the error occurs after such a short time, this is not even a workaround.

Reversing the client/server roles, with the guest as the server, and the host as the guest, made the host loose its network connection. Attaching with a serial console worked for a little time, until I ran sync, meaning to be followed by a reboot -f, but sync made it hang and I can't ctrl+z/bg the job. I tried to detach and reattach, but now I can't reach the box.

This should be given rather high priority. The operations performed (rsync over nfs) should be considered normal use, nothing fancy.
