[Xen-users] how to resolve the problem: xen 3.4 & centos 64bit & raid& reboot volume group not found ?
Hi all,
I have installed centos 5.4, and installed xen from source by
"make world & make install". Then, I edited grub as below:
title Xen 3.4.2 / XenLinux 2.6.18
root (hd0,0)
kernel /xen-3.4.2.gz
module /vmlinuz-2.6.18.8-xen ro root=/dev/VolGroup00/LogVol00
rhgb quiet
module /initrd-2.6.18.8-xen.img
and no error until now. I reboot my system and boot from Xen 3.4.2 /
XenLinux 2.6.18.
Then, error printed like this:
Reading all physical volumes. This may take a while...
Activating logical volumes
Volume group "VolGroup00" not found
Trying to resume from /dev/VolGroup00/LogVol01
Unable to access resume device (/dev/VolGroup00/LogVol01)
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
...
Switching to new root and running init. Kernel panic - not syncing:
Attempted to kill init!
To be noted, I did have mkinitrd.
Who can help? Thanks a lot.
Best Wishes!
Qiang Ma

It''s simpler to just use Centos'' kernel-xen rpm. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks for you reply. In my case, I have some experiments need to add a few code in the source. So I recompiled and installed the xen from source. This computer is 64bit and RAID. And I do this successful in another computer, but difference is that 32bit and no RAID. Thanks a lot. Best Wishes! Qiang Ma On Fri, May 14, 2010 at 12:18 PM, Fajar A.

So I recompiled and installed the xen from source.xen or the kernel? If you only change xen (hypervisor and userland), you can use Centos'' kernel-xen with your self-compiled xen. If you change the kernel, then perhaps you''re just missing the raid drivers. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Now xen, but later I want to change kernel too. Yes, maybe missing the raid drivers. I want to add raid driver, can you tell me how? On Fri, May 14, 2010 at 2:25 PM, Fajar A.
