[Xen-users] Populating a guest image

["Ferreira, N. L. (Nuno)" <n.l.ferreira@xxxxx>]

Hi *

I'm training a bit on the subject "Populating a guest image".
My goal is to build a guest image of Scientific Linux (SL) and clone it 
whenever necessary.
I'm trying both xen-strap (http://www.gridpp.ac.uk/wiki/Xen-strap) and 
virt-install utilities to install into a LVM (wanted a non-graphical tool) .
Xen-strap installs very well SL creating separate swap and root 
partitions, which is cool for later backup.
This utility creates the domU guest kernel on dom0. Thus, the guest 
configuration files reads kernel and ramdisk from dom0.
virt-install does the same good job, but the guest kernel is installed 
on the domU boot. Guest configuration file uses in this case the pygrub 
bootloader.
My questions are:

1 - Virt-install creates self-contained guests (kernel inside domU) 
whereas xen-strap not.
Which one of these is easier to migrate to other similar physical machines?

2 - Is it possible to convert a domU which reads the kernel from dom0 to 
a self-contained guest, like the one created by virt-install? If yes, how?

Cheers,
Nuno
