I have managed to boot Fedora11 and OpenSolaris 09.06 as PV domUs since my 
hardware can't do hvm.  It is usually just a case of giving pygrub the correct 
boot arguments and making sure the .iso is the first line in the disk = [] 
stanza.

e.g.

Fedora 11:
bootloader = "/usr/bin/pygrub"
bootargs = "--kernel=/isolinux/vmlinuz --ramdisk=/isolinux/initrd.img"
disk = [ 'file:/misc/iso/fedora/Fedora-11-x86_64-DVD.iso,xvdc:cdrom,r' ]

OpenSolaris:
bootloader = "/usr/bin/pygrub"
bootargs = "--kernel=/platform/i86xpv/kernel/amd64/unix 
--ramdisk=/boot/amd64/x86.microroot"
disk = [ 'file:/misc/iso/solaris/OpenSolaris/osol-0906-x86.iso,xvdc:cdrom,r' ]

I haven't managed to get the livecd for FC11 to work as it seems the kernel on 
the disk doesn't have domU support.  OpenSolaris doesn't seem to support the PV 
virtual fb yet so only command line mode.
