virtio-net crashing (stop sending traffic)

[prometheanfire]

I'm in the #kvm channel on freenode and have been experiencing the same issue. I thought it was virtio-blk (disk). I was told there was a patch submitted to trunk on Feb 8 to kvm. Here is the information I gathered from mjt.

I've the same problem...

I substitute e1000 with rtl3189 and the problem disappear. May be e1000 bugged?

 

[prometheanfire]

I haven't tried it with other network interfaces, only virtio, but from what I could gather, the race condition only happens when there is a bunch of network activity from a bunch of different nodes.

then ... I must to use rtl3189. Are there e1000 upgrades?
