Alex, 

Thanks for reply. Here is the debugger info: 


[root at XenTester su]# virt-install -p -d 
Thu, 15 Mar 2012 10:04:04 DEBUG Launched with command line: 
/usr/bin/virt-install -p -d 
Thu, 15 Mar 2012 10:04:04 DEBUG Requesting libvirt URI default 
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 at XenTester su]# virt-install -p -c xen:/// 
ERROR Host does not support virtualization type 'xen' 
[root at XenTester su]# virsh uri 
xen:/// 

[root at XenTester su]# 

Any other possibilities?
