Xen users - Jun 2009 - Install Centos-5 as DomU on Debian Dom0

Hi all,

I''m trying to install Centos-5 as DomU on Debian (lenny) Dom0.

After some googling I see that it''s possible install using xen-tools
via command:

xen-create-image --dist centos-5 --rpmstrap --hostname=centos-test
--ip=192.168.0.3 --mirror
http://ftp.tlk-l.net/pub/mirrors/centos.org/5/os/x86_64/CentOS --force
--install-method=rpmstrap

problem is that I don`t see where I can get rpmstrap binary and source
as well for lenny, my toughs is that maybe this method is not so good
if there is no package in lenny :)

I need suggestion based on someone''s experience in installing Centos
and Fedora guests on Debian host.

Thanks!
Evgeniy

This should work : http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU
Another method would be installing as HVM (so you can install with DVD
iso) then convert it to PV.

I cannot see any rpmstrap for lenny; however, rpm for lenny is available. Both
rpm and rpmstrap are
available for etch.

You can use jailtime.org ready images to start with. Once you see everything
else is fine and
working well, you can go ahead to have your own images using ''yum
--installroot...'' from a centos
instance.

Kickstart should also work; I have not tested, though.

Thanks.

What does PV mean here? I am using xen-3.3.1 on fedora 9. I use
virt-manager to manage xen. It''s really comfortable, I can remotely
manage
the VM''s and live migrate them. But never I came across converting an
image
to PV.

Thanks,

PV = ParaVirtualized guest.

Correct, virt-manager is a usable GUI. I''ve never used it on Debian
though (which is the OP environment), so I can''t comment whether or
not it''d be the best choice.

Usually you wont''have to :)
Some scenarios where it would be useful:
- you have a PV-aware OS (RHEL5, for example), but for some reason you
want to install directly from DVD (which is not supported for PV
guest)
- you have a PV-aware OS, working great on a  physical machine or
other virtualization solution, and you''ve succesfully convert it to
HVM guest (using some P2V method), but you need more performance only
available from PV guest.
- fun experiment :D

Take a look at this thread for a how-to

My bad, I use paravirtualized guests. It''s just that I didn''t
know its
termed as PV. Virt-manager, I think it automates the conversion of a linux
kernel to PV, because when I select a linux installation source tree it
takes some-time fetching and converting the kernel and initrd, or it may
even replace the kernel and initrd with the xen-domU kernel and initrd.

I haven''t tried the P2V method. That will be a fun experiment. Will try
that one soon.
