Profile bellow works fine to start OSOL DomU install at Xen 3.4.2 Dom0 (2.6.31.6 pv)
root@ServerKoala:~# cat osol.install
name="OSOL127"
memory=2048
bootloader="/usr/local/bin/pygrub"
kernel="/platform/i86xpv/kernel/amd64/unix"
ramdisk="/boot/amd64/x86.microroot"
disk=['phy:/dev/loop0,xvdc:cdrom,r','phy:/dev/sda9,xvda,w']
vif=['bridge=eth0']
Same profile cannot find kernel on ISO image at Xen 4.0-rc1-pre Dom0 (2.6.31.6 pv)
I just uninstalled old Xen 3.4.2 and installed freshly been built 4.0-rc1-pre on top of Ubuntu 9.10 Server.
