I want to know what is the meaning of above output and what you wanted to
see in it.
I want to know it for my own understanding so please give some url where you
debug
virt-manager or such things because what you asked I did not had a clue of
it.

Ohh ok.Thanks for clarifying that out.

But this time on my non VT machine it is failing.
Here is what I did
1) Download ubuntu 10.04 32 bit ISO
2) Kept it in /var/www (apache2 is running)
3) renamed it to ubuntu.iso
and when I reached a stage where installation begins I gave path
http://localhost/ubuntu.iso
but I got an error saying any installable distribution not found.
4) After this I did
mkdir /var/www/sk
mount -t iso9660 /var/www/ubuntu.iso /var/www/w -o loop
and this time during the installation I gave path
http://localhost/<http://localhost/sk>
w
I was able to see the contents in browser
http://localhost/<http://localhost/sk>w which
you will see in a normal CD.
But beginning installation I got same error
DistroInstaller.py", line 249, in prepare
self._prepare_kernel_and_initrd(guest, distro, meter)
File "/usr/lib/pymodules/python2.6/virtinst/DistroInstaller.py", line 194,

File "/usr/lib/pymodules/python2.6/virtinst/OSDistro.py", line 110, in
_storeForDistro
baseuri)
ValueError: Could not find an installable distribution at '
http://localhost/w'
So is the above way wrong to do?

here is the output
virsh --connect xen:/// version
Compiled against library: libvir 0.7.5
Using library: libvir 0.7.5
Using API: Xen 3.0.1
Running hypervisor: Xen 4.0.0
