Might be useful for you if you wish to get a debianized openvz-kernel.
Yet another solution is to use alien:
http://wiki.openvz.org/Install_kernel_from_RPM_on_Debian_6.0
The bad thing about it is it's not a "native" way. The good thing is you
have the same bit-by-bit binary kernel which we test a lot.
In the meanwhile I have tried two of the suggested solutions:
* RHEL6-kernel (debianized with alien)
* proxmox-kernel from their repository (which for the 2.6.32 version
says it is based on RHEL6)
(I haven't looked yet into building my own with CoolCold's script)
I didn't have troubles to install either of those. However, both expose
the exact same problem. The network bridges vzbr0 and vzbr1 do not work
correctly and I need those for the veth devices of the containers.
Networking without those bridges seem to work fine, but when the bridges
are active, TCP connections fail to work. UDP seems to be not affected,
both inbound and outbound connections work. However, with TCP I can only
establish outbound connections, but as soon as the connection is
established, nothing is received on the other end anymore. Nor can I
send from outside to the machine with vzbr0.
Our problem looks very similar to the one described here:
https://bugzilla.redhat.com/show_bug.cgi?id=623199
Could it be that current stable OpenVZ suffers from the same issue? Or
asked differently: Is the current stable OpenVZ kernel based on RHEL 6.0
which does not contain the fixes as described in:
http://rhn.redhat.com/errata/RHSA-2011-0542.html
If you go to http://wiki.openvz.org and put RHSA 2011 0542 into a search
box you will get an answer,
which is kernel 042stab013.1 released a bit less than a year ago, end of
May 2011.
So I am pretty sure the bug you are referring to is fixed.
Anyway, please file a new bug to bugzilla.openvz.org, and provide a
simple scenario of how to reproduce it (please write a complete report).
