Bug#576838: KVM: networking stack tanks after page allocation failure
Package: linux-image-2.6.32-2-amd64
Version: 2.6.32-8~bpo50+1
Severity: important
I'm running a tor exit node on a kvm instance, it runs for a little
while (between an hour and 3 days), doing 30-40mbit/sec and then
suddenly 'swapper: page allocation failure' happens, and the entire
networking stack of the kvm instance is dead. It stops responding on
the net completely. No ping in or out, no traffic can be observed
using tcpdump, the counters on the interface no longer change
(although the interface stays up).
To get things back, I have to restart the kvm instance, no amount of
module reloading, networking reconfiguring will bring things back, it
is one unhappy camper. No, there is no firewall involved. Hardware has
been replaced, in case that is the issue, but so far nothing has
improved.
This is a stable system, it was running the stable kernel, but in an
effort to resolve this problem we've bumped up the kernel rev to use
the backported 2.6.32-2 linux-image package on both the host system as
well as the kvm guest. The host is running qemu-kvm
0.12.3+dfsg-4~bpo50+1.
This is what the interface looks like when it is down:
