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

[Joe Kislo]

We use vmware ESXi, and we were crippled by this bug (we had to rebuild
several systems back to karmic because they were so unusable).
Somewhere in the past month a kernel upgrade seems to have resolved this
issue for us.  We could reproduce this problem easily:

Remote System:
cat /dev/zero | nc -w 4 -l -p 5000

Vmware lucid system:
nc othersystem 5000 > /path/on/nfs

That could reproduce the issue in a few seconds.  Now that runs for
30+mins w/o any issues, and our "real world" scenario use case appears
fixed too.
