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:
/usr/bin/virt-install -p -d

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?
