Hi Su,
If you're using a libvirt upstream then configure & compile it,
it should automatically check your xen hyperviosr, for example:
[root@202 libvirt]# ./configure -h|grep xen
--with-xen add XEN support [default=check]
--with-xen-inotify add XEN inotify support [default=check]
--with-xenapi add XenAPI support [default=check]
--with-libxl add libxenlight support [default=check]
As usual, you don't need to do extra operation, if you also compile
xen source codes by yourself, I'm not sure whether you put xen to
different path then libvirt hasn't found it in default place.
Regards,
Alex

Alex,
Thanks for reply. Here is the debugger info:
[root@XenTester su]# virt-install -p -d
Thu, 15 Mar 2012 10:04:04 DEBUG Launched with command line:

Thu, 15 Mar 2012 10:04:05 DEBUG Received libvirt URI qemu:///system
I don't know why your libvirt URI is qemu:///system in here, I assume
you haven't changed libvrt default URI, if you specify a URI with
virt-install such as virt-install --connect=xen:/// -p -d say what?
Thanks,
Alex

Hi Su,
Could you attach your virt-install log file as a attachment?
for example, log file is put in $HOME/.virtinst/virt-install.log.
or using virt-install with -d option then paste debugger info
in here.
Regards & Thanks,
Alex

Good. The next step is determining which hypervisor you are connecting
to by default:
virsh uri
If that isn't right (for example, if it returns qemu:///system), then
you need to modify how you are calling virt-install to pass an explicit
URI (or set LIBVIRT_DEFAULT_URI in your environment). Try 'virt-install
-c xen:///' to force libvirt to talk to the xen hypervisor.
http://libvirt.org/uri.html gives more details on setting a URI.

The issue hasn't been eliminated. Here is the running script:
[root@XenTester su]# virt-install -p -c xen:///
ERROR Host does not support virtualization type 'xen'
[root@XenTester su]# virsh uri
xen:///
[root@XenTester su]#
Any other possibilities?

But I believe I've already installed Xen successfully. Do I need to install another driver for the connection?
