Thanks Dustin, it works if I define the storage as "hda", both with file
and ext3 partitioned FS storage. Just as curiosity, you wrote that "the
operating systems you are trying to install do not have PV drivers".
What do you mean exactly? I always thought that logical volumes are
presented as "raw" block devices (like an unpartitioned hard disk) by
Xen to the guest systems. Or you mean that the given guest OS cannot
handle physical volumes? It seems strange, because Oracle's Enterprise
Linux installs LVM by default, so it should use without any fuss.
Thanks again for your help!

Assuming that the log message you found does not indicate an issue,
it would appear that the problem could be that the operating systems you are
trying to install do not have PV drivers. Try changing this:
disk = [
'file:/xenimagefs/debmed.img,xvda1,w','file:/xenimagefs/debian-502-amd64-net
inst.iso,hdc:cdrom,r' ]
to this:
disk = [
'file:/xenimagefs/debmed.img,xvda,w','file:/xenimagefs/debian-502-amd64-neti
nst.iso,hdc:cdrom,r' ]
and then this:
disk = [
'file:/xenimagefs/debmed.img,hda,w','file:/xenimagefs/debian-502-amd64-netin
st.iso,hdc:cdrom,r' ]
Note that I am assuming that debmed.img is blank or a partitioned
image, if it is an image that is not partitioned, the above will not work,
but I am not certain that you can provide a partition instead of a disk
image to an HVM domU anyway.

Subject: [Xen-users] storage is not detected during guest OS install
Hello,
I am running Xen (3.2-1-amd64) on Debian (Lenny) and have the following
problem. I installed Openfiler (from tarball) and works like a charm,
both with file and logical volume backed storage. However, when I tried
to run Enterprise Linux (Oracle), no matter how and which kind of
storage was defined for the guest system, it didn't recognize during
install. I also tried to install Debian, same problem. Neither logical
volume, nor file based storage detected during install, so even if both
of the guest systems are booting flawlessly, practically I'm with a
diskless system. This is the config file I used with Debian:
------------------------------------------------------
name = 'debmed'
kernel = '/usr/lib/xen-3.2-1/boot/hvmloader'
builder = 'hvm'
bootloader = '/usr/lib/xen-3.2-1/bin/pygrub'
memory = '512'
disk = [ 'file:/xenimagefs/debmed.img,xvda1,w',
'file:/xenimagefs/debian-502-amd64-netinst.iso,hdc:cdrom,r' ]
boot = 'dc'
vif = [ "mac=00:3e:3e:3e:3e:75,bridge=eth0,type=ioemu" ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
vnc=1
vnclisten="0.0.0.0"
vncdisplay=1
vncconsole=1
vncdisplay = '3'
vncpasswd=''
------------------------------------------------------
No useful hints in the logs, except this one (it means nothing to me,
but maybe rings a bell for somebody):
"I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0"
This is the last entry after booting the guest OS, I always got this one
whether I tried to use logical volume as storage, or file. Since I
almost has no experience with Xen, chances are that I did something
wrong; all hints/comments are appreciated!
