Re: [Xen-users] Install ubunto domU
When done DomU may be loaded via profile with your's patch back ported to Xen 4.0 :
root@ServerLnx:/home/boris/ubuntu# cat ubuntu.py
name="U10PV"
memory=2048
disk = ['phy:/dev/sdb5,xvda,w' ]
vif = [ 'bridge=eth0' ]
vfb = [ 'type=vnc,vncunused=1']
bootloader = "/usr/bin/pygrub"
vcpus=2
On DomU :
# lsmod | grep xen
xen_fbfront 7225 1
fb_sys_fops 1611 1 xen_fbfront
sysimgblt 2547 1 xen_fbfront
xen_kbdfront 4249 0
sysfillrect 3949 1 xen_fbfront
syscopyarea 3640 1 xen_fbfront
xen_netfront 17890 0
xen_blkfront 10697 3
You are right regarding VFB.
Boris.

1. I never really found a use for vfb. This is ubuntu server. If you're looking for a desktop after the install you can modprobe xen-fbfront.
2. If you're deploying a lot of machines i have used http-replicator to cache the packages so they're only downloaded once.

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.

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 ?
Boris.

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.
