Re: [Xen-users] Xen and LVM

The problem though is its not even getting to load the OS, it refuses to even mount the partition saying its already mounted by another guest ( I am using full partitions not a loopback file system ).

All 4 domains where created at the same time using the same image and they randomly work or don't work its not a specific issue.

Sometimes the problem is related to allowing access to the seperate swap partitions not the OS partition as well, In that case when its playing that game I have tried redoing the swap partition 100% and it still says its already in use by another guest os

I downloaded it from somewhere, centos image.. It runs with the older version of Xen without a problem so the image does work.

unfortunately, I have found that if it runs with an older version of xen, it will fool you by mostly running on 3.0. I would seriously recommend building a new guest image. It's not terribly difficult, only time tedious. the steps below work for me on ubuntu but there's nothing keeping it from being distribution independent.

"install" onto a file disk image using qemu
create a new partition-less disk image
mount the root partition on a loopback device using losetup
mount your partition-less disk image also using a loopback device.
cp -a from the root partition to the partition-less disk image
cp -a domU modules onto the partition-less disk image
fixup fstab, host names, ethernet interface definition (there are probably more but I can't remember right now)

unmount everything (very important as my recent experiences shown ;-))

Create your .xm file

xm create ...

I believe this will give you better results. Or if you prefer, I can also make available an ubuntu very raw disk image (i.e. fresh out of the qemu oven).
