Xen devel - Mar 2011 - Improving xen-qemu-dm-4.0 dependencies

Hi,

When I first built my Debian package, I needed to depend on qemu-system
| qemu, since there was no other ways to pull needed BIOS files.

It seems the situation changed, and that I could depend on less stuff
from the qemu package. Maybe only the package named "etherboot" and
"vgabios". To do that, my plan is to simply package a folder named:

/usr/share/xen/qemu

with in it symlinks, in a similar way of what you can find in

/usr/share/qemu

So, my question is simple. Out of this, what do I need for xen-qemu-dm?

   29 Dec 14 13:16 vgabios-cirrus.bin -> ../vgabios/vgabios.cirrus.bin

Obviously, I know I would need the keymaps folder (from the qemu-keymaps
package).

I can second guess that I would need both vgabios and others. May
someone give me an exhaustive and exact list, so that I don't do any
mistake in fixing Debian bug #607490 ?

Thanks in advance,
Cheers,

Thomas Goirand (zigo)

I think so.

The vgabios and rombios used by Xen are not the same as the ones
used/provided by qemu. I think you need to use the stuff from
tools/firmware/{vga,rom}bios in the Xen source not anything provided by
qemu.

Now, the issue is these are in the source package of the hypervisor, not
in the Git of xen-qemu-dm. Would you consider moving them to it? Or
would you advise me to simply copy the tools/firmware/{vga,rom}bios
folder into my source package and live with it like that?

Or maybe, we should create a new "xen-qemu-roms" binaries out of the
Xen
hypervisor package? Bastian, if I give you a patch against your package
to add a xen-qemu-roms binary, would you accept it?
