Pkg xen devel - May 2010 - Bug#562703: qemu-dm missing from xen-utils-3.4

I tried using

 
http://ftparchive.gplhost.com/debian/pool/lenny/main/x/xen-qemu-dm-3.4/xen-qemu-dm-3.4_3.4.2-1_amd64.deb

But my hvm instance wouldn't start.

I got this in the qemu-dm log

domid: 22

]
disk = [ 'file:/home/win2003/miniserver/root_fs,ioemu:hda,w' ]
extra = ""
restart = 'onreboot'
vcpus = 2

This is a config file that used to work under Xen 3.2

Hi,

First, thanks for this important feedback.

What I believe is happening is that qemu can't find its keyboard definition
file and just exits... :(

xen-qemu-dm depends on qemu-system because that is the only package that holds
the keyboard definition in Debian. It is highly not wanted in a distribution to
have multiple copies of the same file. But as we don't need the full of qemu
in kvm or xen, but just the bios and keyboard definitions, it was planned that
the files would be sent to a separate binary package.

Maybe this has already happened and I was not aware of it. Can you please use
apt-file to search for the correct dependency that is mising? Eg something like:

apt-file search en-us PIPE grep keymaps

(sorry, can't fine how to type a PIPE in the N900, if you do please tell
me...)

Then I suppose that just a symlinks to that file in:

/usr/share/xen/qemu/keymaps/en-us

will fix your issue with the keyboard definition. In any ways, I am VERY
interested by your feedback here, as clearly, it seems there's a dependency
or path issue here, that I didn't see (maybe because I did tests on my
laptop only, and this laptop has a shitload of stuff installed, including qemu
itself).

Should this package work okay with the version of Xen in Squeeze? Which
is 3.4.3. Or is there a more up to date version of qemu-dm in the later
version of Xen?

I have tried to install Windows Server 2008 R2 which always fails at 9%
of the installation.
