Subject: [Xen-users] Domu has no disks
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

Hi All,
It seems my problem is in the association between a disk in dom0 and the
virtual disk in domu. 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?
Thanks in advance,
Barry
