Hello,
This is my first post to the list and I am new to Xen, so please excuse my
ignorance.
I have Xen 4.0 running on Debian Squeeze with Squeeze as dom0. I am trying
to install Ubuntu Lucid 10.04 as a guest. I am using the install cd iso. I
think I should be able to do this based on this quote from
http://wiki.xensource.com/xenwiki/XenOverview. From the ''Installing new
Paravirtual (PV) guests'' section, ''Ubuntu 10.04 ("Lucid
Lynx") installer can
be booted as a Xen PV guest and installed easily that way. ''.
The problem is once the Ubuntu installer starts it cannot find the cdrom.
Also if I use the net-install method, the installer can''t find the
virtual
disk to install to. So my problem is not getting domu to boot but not having
any disks once it does.
My domu configuration file is based on the xmexample1 configuration that was
packaged with Xen. Rather than posting the whole file here are the changes I
made:
kernel = "/etc/xen/install_kernels/cd-installer/vmlinuz"
ramdisk = "/etc/xen/install_kernels/cd-installer/initrd.gz"
builder=''linux''
memory = 512
name = "Lucid-server-install"
disk = [
''file:/home/barry/iso/ubuntu-10.04.3-server-amd64.iso,xvdc:cdrom,r'',
''tap:aio:/xen-vm-fs/lucid-vm-disk,xvda,w'' ]
root = "/dev/cdrom ro"
The kernel and initrd.gz are copied of the cd iso. In the disk statement I
have tried hdc, hda, sda, sdc to no avail.
I have Googled, searched this list, the debian list, Ubuntu documentation
and the Xen.org documentation and not found the answer. Can anyone spot
where I''ve gone wrong? Please ask for more information or suggest how I
can
debug this problem. One more piece of information, this machine does not
have a virtualization process so paravirtual is a must.
Thanks in advance for any help
Barry

---------------------
You want to use the CD ISO as source, but not as boot object.
What I did is mount the ISO in a webroot (/var/www/), copy off the netboot
vmlinuz and initrd.img and them as targets to
xm create (kernel/ramdisk).
Now you are booting into a PV install using xm.
THis works very well and is fast.

I mounted the iso on my web server. When the installer ask me what Ubuntu mirror to use, I specify http://192.168.0.100/ubuntu which is where the iso is mounted. The installer comes back with ''invalid release file''. I tried several directories that had release files and still no luck. I''m really missing something here, but I don''t know what.

Networking seems to work fine. How do I tell if the mechanism is working. I guess what I what to know is if blkback and blkfront are working, and if not what needs to be installed? I used the package from the Debian repository (squeeze) to install xen plus the updated xen-utils-common from sid ( to resolve the issue with the missing hotplugpath.sh script). Can anyone point me in the right direction?
