I think I understand: you're using DHCP, and the server is assigning domains random addresses. Just connect to the domain via it's console. The easiest way to do this is just to put '-c' on the 'xm create' command line. Alternatively, use 'xm consoles' to list all the available consoles, then connect to the listed port e.g. xencons localhost 9601 > After running some domains I got a failure on fcdsk on bootup.

Do you recommend to have one partition > for each domain? At least it seems like I have something wrong in the > configs for HD setup. You could give each domain it's own physical partition. Alternatively, use LVM to dynamically chop the partition up into volumes, each of which you can assign to a domain e.g. disk = [ 'phy:/dev/vg01/vm%d,sda1,w' % (vmid) ] Alternatively, put a file system on the partition and export files to domains using the loopback device (losetup). This enables you to use sparse files, allocating disk space on demand. Make sure you remember to put a filesystem and populate whatever you decide to use as the domain's block device!
