Hello,
When I needed to build Xen guests under Debian I could follow more or less the instructions in http://preview.tinyurl.com/2oc48r and the advantage of this approach is that it allows me to setup the Xen guest directly on the LVM partition without making it consider the LVM partition as an entire disk with a partition table.
The advantages of this approach are: 1. I can add more LVM's later, or share LVM's at the host level among multiple Xen guests. 2. I can easily grow/shrink the Xen guest's disks. 3. I can access the Xen guest's filesystem much more easily 5. Probably less overhead in having LVM->parition->LVM.
But I didn't find a way to achieve this with CentOS 5's automatic tools. Is this supported by CentOS as a Xen host or do I have to find my own way?
Thanks,
