[Pkg-xen-devel] Bug#631102: xen: Xen guests on Squeeze lose networking randomly

[Kevin Bowling]

Package: xen-hypervisor-4.0-amd64
Version: 4.0.1-2
Severity: grave
File: xen
Justification: renders package unusable


Debian Squeeze Dom0, up to date.

Networking is handled by OS scripts, such that br0 and br1 are bridge interfaces.

Without warning, the DomU (Ubuntu 10.04 LTS) loses inbound connectivity.  It tends to happen after several hours.  It doesn't seem to be affected by throughput and is triggering on very small ammounts (5MB in and out over that time).  Having active traffic doesn't help, it still dies.

Updated the DomU to kernel 2.6.35 with no change.  I suspect the problem lies on the Dom0 side.

It's possible to "revive" the DomU for a short while by getting a console with xm on Dom0 and then sending pings to the Dom0 and other hosts.
