[Bug 579276] Re: Lost network in KVM VM / virtio_net page allocation failure

[RoyK]

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.
