Hi,
if you are having a GUI then please use virt-manager.
In case you are accessing the server remotely.
Please follow this method on CentOS
yum install virt-manager
make sure
in your sshd_config
X11 Forwarding is enabled login remotely.
To be able to export X from a remote CentOS server which does not have
Gnome Desktop Manager running
a library xorg-x11-xauth is needed to be installed on CentOS server.
I got this solution here
http://bugs.centos.org/view.php?id=2391
Then login remotely
ssh root@centosdom0 -X
virt-manager
you will get a nice GUI and then you can give path to ISO,HTTP,NFS
what ever Ubuntu has.
You should be able to install.The other way of creating config files
converting HVM to PVM will be difficult.
Please use a nice GUI from virt-manager it will help you rather than
going through complex process
virt-manager can be used on various opearing systems
Debian,Ubuntu,Fedora,RedHat.
http://virt-manager.et.redhat.com/
The steps may not be exactly as mentioned on the following link
http://www.cyberciti.biz/tips/rhel-centos-xen-virtualization-installation-howto.html
but using GUI for some time you will get an idea.
I have attached a file go through it.
It is a correction of some ones blog at
http://www.ideyatech.com/2010/05/virtualization-with-ubuntu-1004-lucid-lynx/
that blog is using Ubuntu as Host OS but the steps here in your case
should be similar.
It should help you.
