Dear *, Boris
I tried to follow your steps (installing Lucid x86_64 PV domU on a CentOS 54 x86_64 dom0, running xen 3.4.2 from gitco) ... but was not successful. Something is still escaping me.
Installation went just fine till the end after a "xm create -c lucid.xen" (see below).
After installation (without any modifications to what was installed) I edited the xen config file (test.xen, see below) to boot with pygrub instead. But I get the following error:
Error: Boot loader didn't return any data!
I checked that the new domU does not have /usr/bin/pygrub, and this explains the error.
So Boris, how did you boot your ubunto based domU after a netboot installation?
I did not tried yet the debootstrap method also suggested ... first I want to know what I'm doing wrong here.
I'm a bit lost on setting up an ubunto domU, first time getting outside RedHat like OSes. So if there are some good working links to blogs/tutorials on how to install ubunto domU's on RedHat like dom0's I'll appreciate.
Cheers,
N.
P.S. Steps taken :
1 - lvcreate -n domu.ubunto.lucid -L 4G vg1
2 - mkfs.ext3 /dev/vg1/domu.ubunto.lucid
3 - wget http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/vmlinuz
4 - wget http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/initrd.gz
5 - cat lucid.xen
name = "lucid"
memory = 1024
disk = ['phy:/dev/vg1/domu.ubunto.lucid,xvda,w' ]
vif = [ 'bridge=eth0' ]
kernel = "/mnt/dom0/data/domu.setup/ubunto/lucid/vmlinuz"
ramdisk = "/mnt/dom0/data/domu.setup/ubunto/lucid/initrd.gz"
vcpus = 1

on_crash = 'destroy'
6 - xm create -c lucid.xen
... installation goes just fine ...
7 - cat test.xen
name = "test"
memory = 512
maxmem = 1024
bootloader = '/usr/bin/pygrub'
disk = ['phy:/dev/vg1/domu.spyder.root,xvda,w' ]
vif = [ 'bridge=eth0' ]
vcpus = 1
class="im">
on_reboot = 'restart'
on_crash = 'restart'
8 - xm create -c test.xen
Using config file "./test.xen".
Error: Boot loader didn't return any data!

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.
