Re: [Xen-users] xen + centos + areca raid issues
Thanks for the quick response Artur.
The reason there is nothing in the config file about the kernel is because of pygrub and centos's way to put the kernel inside the domU (atleast thats what i had learnt by reading the thread on this list)
I cannot mount the domU image file since it contains LVM volumes in it. Here is the partition structure of the image file aaa.
Disk aaa: 0 MB, 0 bytes 255 heads, 63 sectors/track, 0 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System aaa1 * 1 13 104391 83 Linux aaa2 14 1300 10337827+ 8e Linux LVM Partition 2 has different physical/logical endings:
phys=(1023, 254, 63) logical=(1299, 254, 63)
I tried to use lvm tools to recognise the volume as well, however doesn't work. For this, i used the following
losetup /dev/loop0 /home/xen/aaa
Now the entire image is present as /dev/loop0. However when i try to run vgscan, it doesn't recognise the lvm volume at all.

There's nothing about your new kernel in your domU-Configuration. There should be something like: kernel = '/boot/vmlinuz-2.6.18-5-xen-686' poniting on the new compiled kernel.
Moreover you should copy the new kernel modules to e.g. /lib/modules/.
Dont worry about your data in the domU. You can mount your Image or the according partition like this:
Partition: ==========
mount /dev/XdaX /mnt
Image: ====== mount -o loop /yourfolder/vm_disk.img /mnt
Maybe the best would be to create a new VM with xen-create-image.
Hope thats gonna help you a bit.
Cheers,
Artur
