Install SNV103 PV DomU with ZFS image at Xen 3.3.1 openSUSE 11.1 Dom0 (all 64-bit)

During installation phase we would have to drop to shell and undertake some special actions to prepare runtime profile.Pygrub won’t be able to load DomU utilizing ZFS based image. In particular, ZFS-ID of boot environment will be obtained to compose extra line in runtime profile.

Start install as usual via profile :-

name = 'Solaris103PV'
memory = '2048'
disk = [ 'file:/home/boris/snv103.iso,6:cdrom,r','phy:/dev/sdb12,0,w']
vif = [ 'bridge = br1' ]
bootloader = '/usr/bin/pygrub'
kernel = '/boot/platform/i86xpv/kernel/amd64/unix'
ramdisk = '/boot/amd64/x86.miniroot'
extra = '/platform/i86xpv/kernel/amd64/unix - nowin -B install_media=cdrom'

Select ZFS on image device and request manual reboot. At the end of package deployment phase drop to shell at DomU and run

# bootadm update-archive -R /a

Copy kernel and boot_archive off the image to Dom0

# /a/usr/bin/scp -S /a/usr/bin/ssh \
/a/platform/i86xpv/kernel/amd64/unix \
192.168.1.33:/etc/xen/nevada
# /a/usr/bin/scp -S /a/usr/bin/ssh \
/a/platform/i86pc/amd64/boot_archive \
192.168.1.33:/etc/xen/nevada

Get the ZFS-ID of the /ROOT/snv_103 zpool. First, find out the pool_guid.
Follow [1]:-

# zpool get guid rpool
# NAME PROPERTY VALUE SOURCE
rpool guid 17306096753167233998

Then run :-
