Re: [Xen-users] Install ubunto domU

I was able to start installer :

# xm create -c ubuntu.cfg

and see several obvious disadvantages (vs HVM convertion) :

1. VFB doesn't work
2. After selecting local mirror "Installing base system" is already running for 15 min
at 2MB/sec ADSL connection.

Virt-install HVM :

# virt-install -n LucidSRV -r 1024 --hvm --vnc -f /dev/sdc7 -c /root/isos/UbuntuServer10.04.iso --debug

I don't know what you mean exactly, but Karmic,Jaunty,Intrepid Servers PV DomUs may be also installed via debootstrap. View for instance:

http://bderzhavets.wordpress.com/2009/05/02/debootstrap-ubuntu-jaunty-pv-domu-at-xen-331-f10-dom0-kernel-2630-rc3-tip/
 

Does Ubuntu provide URL acceptable for " --location URL" option of virt-install ?

Ubuntu now has a fully PV xen aware netboot installer available, so installing HVM and doing a "conversion" isnt necessary.

As for how to make virt-install work with this, i'm not so sure. I'm assuming its using a debootstrap style install.

Create Lucid HVM via virt-install and load same image via pygrub,

Dear *,

I'm more used to work with RedHat like OSes. Still, I did not denied the request from a user who wants a domU based on ubunto. I usually use virt-install to do the job, with a script similar to this one:

#!/bin/sh
BASE=SL-4.7-i386-pv \
virt-install --nographics     \
             --nonsparse      \
             --paravirt       \
             --noreboot       \
             --file-size=4    \
             --ram=512        \
             --vcpus=1        \
             --name=$BASE-`date +%d%m%y`     \
             --file=$BASE-`date +%d%m%y`.img \
             --location=ftp://linuxsoft.cern.ch/scientific/47/i386/

I tried several --location values for ubunto (e.g. http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/ )
but I'm always getting the following error:

Starting install...
ERROR    Could not find an installable distribution at 'http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images'

Can someone point me to the right direction? Clearly I'm missing something, probably virt-install only works for RH like. Also open to suggestions of installing domU's using other methods.
Thank you,
N.
