I see similar behavior: After a week one of my guests' network totally
stops to respond. Only guests using virtio networking get hit. Both
windows and linux guests are affected.
My guests in production use e1000 and have never been hit.
While that can be a coincidence it seems very unlikely: Out of 3
virtio guests 2 have been hit, one repeatedly.
Out of 3 e1000 guests none has ever been hit.
Observed with kvm-83 and kvm-84 with the host running in-kernel KVM
code (linux 2.6.25.7)
Might it be that some counter overflowed? What are the packet counts on
long running guests?
I don't think so.
I just made both counters (TX, RX) of ifconfig for virtio interfaces
overflow several times and everything is still as fast as it should be.
(output of ifconfig, even on an unaffected e1000 guest, might help)
