apport information
** Tags added: apport-collected precise third-party-packages
** Description changed:
Networking breaks after awhile in kvm guests using virtio networking. We
run data intensive jobs on our virtual cluster (OpenStack Grizzly
Installed on Ubuntu 12.04 Server). The job runs fine on a single worker
VM (no data transfer involved). As soon as I add more nodes where the
workers need to exchange some data, one of the worker VM goes down. Ping
responds with 'host unreachable'. Logging in via the serial console
shows no problems: eth0 is up, can ping the local host, but no outside
connectivity. Restart the network (/etc/init.d/networking restart) does
nothing. Reboot the machine and it comes alive again.

I am reporting this for spark but this should be valid for any
applications that involve fast data transfer between VMs. The bug has
been reported in centos forums as well.
