No, I mean using a suse dom0 to install a suse pv domu (or a fedora dom0 to 
install a fedora domu, etc.) This is because only the distro in question (suse 
here) knows about the layout of their own install disk, and knows how to run 
the install for you without hiccups, like this. Since you are using a gentoo 
dom0, you are out of luck, trying to install a suse domu.

Again, back to guessing here, since I don't have Gentoo: First, I don't think 
the 'phy:/dev/loop0,hdc:cdrom,r' part of the disk= line is doing anything. Pv 
domus don't understand cdroms. The install= line, and your loop mount of the 
dvd is telling gentoo where your install media is. (Similarly, stdvga= and 
videoram= are hvm options, and will be ignored.)

Here's my guess: after replacing kernel / ramdisk with bootloader, also 
comment out the install= line. That's probably telling gentoo to restart. If 
that doesn't work, I can't help you with this method, but I'll keep working on 
the hvm to pv conversion approach.
