Package: linux-2.6
Version: 2.6.32-18
Severity: normal
At work we have 4 Dom0s, all of them with different hardware. When 2.6.32 with
pv-ops appeared on Debian testing (squeeze) we started testing it.
Everything went fine until we tried to configure an OpenVPN server on a DomU.
We found out that forwarding traffic was not working. We tried hard to debug
the problem (tcpdump, wireshark, etc) and packets reached the DomU but they
never left.
After testing the DomU on every version of the Xen hypervisor (from Debian,
3.2, 3.4 and 4) and on every DomO we have we discovered almost by chance that
with the -xen flavour of the kernel package the problem disappeared. AFAIK the
-xen kernel has the forward-ported patches from 2.6.26, so most probably this
has something to do with pv-ops.
If I can be of any help just ask, I'd be glad to.
Thanks.
