Re: [Fedora-xen] Ubuntu as DomU under Xen/FC5
Thanks Dan --
This gets confusing/tricky...
What exactly do you mean by "the Ubuntu installer"?
Ubuntu says that to install Xen on Ubuntu you should
download Xen from XenSource and integrate it with your
Ubuntu installation
(https://help.ubuntu.com/community/XenOnUbuntuBinaryInstall).
I am not sure if there is an Ubuntu Xen kernel.
I used xenguest-install.py to install the FC5 guest,
but I am not sure that will work with Ubuntu. Will I
need to create my own config file in /etc/xen?
Thanks for your help, any more tips would be
appreciated.

Its unfortunate that most other distros seem to have
gone in the direction
of using some bootstrap / chroot method to installs
guest FS images, because
its pretty much doomed to fail in a mixed host/guest
environment such as
Ubuntu on Fedora. This is why the Fedora approach to
creating guests has
been to boot the regular installer (anaconda) using
a xen guest kernel - it
lets people easily install Fedora guests on
non-Fedora hosts.
There's a couple of options I can think of
- Try and boot the Ubuntu installer using the
Ubuntu Xen guest kernel
and hope it 'just works'.
- Run the Ubuntu installer inside QEMU instance,
and then install the
kernel-xen inside QEMU. Finally shutdown QEMU &
create a Xen config
file to boot the image created via QEMU
- Use a bare-metal Ubuntu host to create the image
& then copy it across
to the Fedora host to run within Xen
- Manually install debootstrap from sources on
Fedora & see if you can
get it working
If the first option doesn't work it'd be worth
creating a bug report for
Debian recommending they try & get it working,
because booting regular
installer with a xen guest kernel is by far the most
portable way of
creating guest images in mixed environments, since
its totally isolated
from whatever the host happens to run.

Dan.
