When I try to install a CentOS 4 domU with virt-install
(xenguest-install is a symlink to the virt-install tool), I get this
error:

ERROR:  Invalid URL location given: [Errno 14] HTTP Error 404:
Content-Length: 345
Date: Tue, 06 Feb 2007 17:30:34 GMT
Accept-Ranges: bytes
Content-Type: text/html
Server: lighttpd/1.3.16

Here''s the command I used:

virt-install -n aserisk -r 128 -f /dev/vg00/asterisk -s 1.2 -b xenbr0 -p
-l http://mirror.linux.duke.edu/pub/centos/4.4/os/i386/CentOS/RPMS/

I''ve tried a number of different locations, but everything fails.  I
have yet to find an example "path/to/tree" example that would help me
understand what I''m doing wrong.

Having said that, I do have running domUs, but I didn''t set them up the
"fedora" way.  That''s what I''m attempting to do now.

Regards,

Ranbir

Never fails...I think I found the answer in this thread (to my problem anyway -
not sure if it applies to the thread starter):

http://www.redhat.com/archives/fedora-xen/2007-January/msg00088.html

That explains what''s going on.  Guess I''ll have to wait until
CentOS 4.5
is out before I can try out the virt-install tool.

The CentOS 4 distro does not suppport paravirtualization. You will have to
do full virtualizated installs, which require local ISO image / CDROM.

I''m running two CentOS 4.4 domU on a FC6 dom0 right now, though they
weren''t created with the virt-install tool.  I want to setup two more
CentOS 4.4 domU, but this time with virt-install - that''s when I had
problems.

I suspect there are some problems though because udev fails to start
when the domU boot.  Also, I have to manually kill nash-hotplugd because
it eats 99% of the CPU.  I didn''t have this problem at all when dom0
was
FC5.

When CentOS 5 is out, I''m going to use it as dom0.  That should run
paravirtualized CentOS 4 domU well (as far as I know).

I want to get a new server so I can have full virtualized domUs.  But,
it''s not in the budget - maybe in a couple of years.

Regards,

Ranbir
