I found some references to similar problems:

http://forum.proxmox.com/threads/3117-virtio-net-crashing-(stop-sending-traffic)
http://www.mail-archive.com/kvm@vger.kernel.org/msg26033.html
http://marc.info/?l=kvm&m=126564542625725&w=2


In particular, I note the patches provided by Tom Lendacky and Herbert
Xu. Are these patches applied to qemu-kvm 0.12.3 or 0.12.4? If so, it
could be a regression?


Thanks in advance for your reply.

Daniel
