well... it is possible ;) because we are allready doing this for over a year. And the installation is quite simple: * you create your logical volumes in the dom0 and mount them * you install a minimal system with yum --installroot= * you create a xen config where you map the logical volumes to the partition inside the domU. The installation instructions can be found on my blog: http://www.raskas.be/blog/howtos/centos-base-image/ And this is how the disk section of my xen config looks like: disk = ['phy:vm_volumes/root-host1,sda1,w' ,'phy:vm_volumes/swap-host1,sda2,w' ,'phy:vm_volumes/tmp-host1,sda3,w' ,'phy:vm_volumes/varlog-host1,sda6,w' ,'phy:vm_volumes/home-host1,sda7,w' ] It would be really great if this would be possible to do with koan, for now we do this with our own create vhost script.
