Attempt of VNC setup on Ubuntu Hardy PV DomU at Xen 3.3 CentOS 5.2 Dom0 (all 64-bit)

Posting bellow describes setup Ubuntu Hardy PV DomU via attacment block device to Ubuntu Hardy HVM DomU at the same CentOS 5.2 Dom0. Standard debootstrap procedure has been used to create initial
image on this device. This step allows to avoid “scp” image files from remote Ubuntu HH box to Dom0 and use /dev/sda(X) with prepared image immediately on the same box,referencing the device from Ubuntu Hardy PV profile.
I’ve also attempted to install “ubuntu_desktop” on PV DomU and activate VNC. This procedure seems to have bugs during “ubuntu_desktop” install on image prepared via debootstrap. However, gnome desktop been installed
still appears to be able perform numerous useful functions.

Create Ubuntu Hardy HVM via virt-install at Xen 3.3 CentOS 5.2 Dom0 providing by Xen 3.3 port via http://www.gitco.de/repo/xen3.3.0 .It can be also done and at Xen 3.3 Dom0 been built from source via hvm-profile,e.g. not using
virt-install at all.
Disk attach block device to prepare Ubuntu PV DomU image via debootstrap.

# virsh attach-disk U8HVM –driver phy /dev/sda10 xvdb
Restart U8HVM and issue at Ubuntu HVM DomU (attached disk will be recognized as /dev/sdb) :-
# fdisk /dev/sdb
and created /dev/sdb1 – 14 GB, /dev/sdb2 – 2GB
# mkfs.ext3 /dev/sdb1
# mkswap /dev/sdb2
# mount /dev/sdb1 /mnt
# apt-get install debootstrap
# debootstrap –arch=amd64 –components=main,updates,universe,multiverse hardy /mnt \
