Xen users - Sep 2009 - CentOS Xen Kernel 2.6.18-164 and Gitco Hypervisor 3.3.1 problem

Hi All,

I upgraded my Dom0 kernel to the above version during a normal yum update. After
reboot, I got some flashed message about not a proper root and then a cannot
sync error followed by an (almost) immediate reboot. I have no clue where this
is logged, if indeed it is. /var/log/messages has yielded nothing, but I suspect
this is way early in the boot process for that. I will try to look for a
start-up kernel switch to stop it rebooting immediately.

Running the kernel straight had no issues. I was more intent on just getting my
server up so reverted to previous kernel and all was back to normal.

I have already asked on the CentOS list and apparently this kernel is not having
any issues with the hypervisor provided under CentOS.

Whilst I try to get a few more details of exactly what those error messages
were, I thought I would ask see if anybody has anything similar or if they have
the above configuration without issue.

Thanks in advance,

Ian.

Are you saying that CentOS Xen Hypervisor is 3.3.1 in meantime ?
I guess normal yum update goes only to CentOS Repo.
I believe that yum install Gitco''s rpms along with gitco''s
repo activated
may bring your hypervisor to 3.3.1

Sorry, I may not have been explicit. I am currently using the Xen hypervisor
from Gitco, which is 3.3.1 and the xen kernel from normal CentOS repos. Xen
hypervisor hasn''t changed, nor did I want it to.

Thanks.

Turned out I have an extra initrd image file for the problematic kernel with the
suffix ".dup_orig" on it. I removed a few old kernels and removed and
re-added the 2.6.18-164 xen kernel and then all was fine.

Thanks anyway.
