Pygrub & install OpenSolaris 2008.11 at Xen Unstable Dom0 with 2.6.29-rc7 pvops enabled kernel

The most recent changes to Xen Unstable now allow to load Solaris Nevada and opensolaris 2008.11 PV DomUs with ZFS image via pygrub. Actually, Xen Unstable Dom0 with Suse’s 2.6.27 xen-ified kernel or standard 2.6.18 kernel will behave the same way.Moreover, install xen-ified kernel seems to be a preferable option due to 2.6.29-rc7 is under heavy development in meantime. My choice of pvops kernel for Dom0 is targeting test purposes first of all. Build pvops kernel per [1] :-

# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
# cd linux-2.6-xen
# git checkout origin/xen/dom0/hackery -b xen/dom0/hackery

To enable Xen support in Dom0 and tune kernel
for yourself:-

# make menuconfig

Now build:-

# make
# make modules_install install
# mkinitramfs -o /boot/initrd-2.6.29-rc8-tip.img 2.6.29-rc8-tip

Reboot with grub entry :-

title Xen 3.4 / Ubuntu 8.10, kernel 2.6.29-tip
uuid 9efba9a5-9f2b-4bf6-b8b5-7d6d53eb02d9
kernel /boot/xen-3.4.gz
module /boot/vmlinuz-2.6.29-rc8-tip root=/dev/sdb14 ro console=tty0
module /boot/initrd-2.6.29-rc8-tip.img

Installation profile :-

# losetup -f /etc/xen/isos/os0811.iso
# cd /etc/xen/vm
# cat os0811.py
name = 'OS0811'
memory = '1024'
disk = [ 'phy:/dev/loop0,6:cdrom,r','phy:/dev/sdb7,0,w' ]
vif = [ 'bridge=eth0' ]
bootloader = '/usr/bin/pygrub'
kernel = '/platform/i86xpv/kernel/amd64/unix'
ramdisk = '/boot/x86.microroot'
extra = '/platform/i86xpv/kernel/amd64/unix - nowin -B install_media=cdrom'


Run :-
# xm create -c os0811.py
and perform straightforward install



Runtime profile:-

# cat os0811.pyrun
name = 'OS0811'
memory = '1024'
bootloader = '/usr/bin/pygrub'
disk = ['phy:/dev/sdb7,0,w']
vif = [ 'bridge=eth0' ]


Load DomU:-
# xm create -c os0811.py



Bring up vncserver and connect to DomU:-
