Xen users - Sep 2008 - Debian testing + xen 3.2.1 + dom0 kernel 2.6.18 + clvm 2.x -> impossible ?

Hi,

I''m trying to setup a dom0 starting from a debian testing installation.
I installed testing, then installed the 2.6.18 kernel from stable and the
hypervisor from testing. After a reboot xen is now up and running. I now want to
use clvm. So I install redhat-cluster-suite and clvm. This installs the kernel
modules for the 2.6.26 and the 2.6.18 kernel. However, the modules for the
2.6.18 kernel are version 1.3x, while for the 2.6.26 kernel are 2.x . Needless
to say, cman will not start.

I then tried to compile de kernel module for my 2.6.18 kernel from source using
the module-assistant. This fails on lm_interface.h, which is not in the 2.6.18
source tree.

Is it really impossible to run clvm 2.x on a dom0 ? Or am i missing something ?
Has anybody used clvm with xen ?

Kindest regards,

Peter.

Clvm 2.02.06 is in Etch, so it surely runs on 2.6.18.

Indeed. But the kernel module is a 1.3 :

ii  redhat-cluster-modules-2.6.18-6-xen-amd64 2.6.18+1.03.00-7+etch4 Redhat
Cluster infrastructure modules for Linux 2.6.18 on AMD64
ii  redhat-cluster-modules-2.6.26-1-amd64     2.6.26+2.20080801-3    Redhat
Cluster infrastructure for Linux 2.6.26 on AMD64

clvmd refuses to start with error :

That''s the reason I''m trying to compile the 2.20080801 version
of the cluster modules for 2.6.18 .

Has anybody got clvmd working with a 2.6.18 kernel ? Or is the error above due
to something else ?

Kindest regards,

Peter.
