Thread-topic: VGA Passthrough
Hi Ben,

I have tried XCI and built it successfully (it's not a big thing and I don't 
like the Buildroot). Anyway, I don't think it is going to solve the problem. 
Xen client is focused on passing through the primary vga card, and is still 
very specific to Intel integrated gfx.

Most of the functionality is already in Xen-3.4-rc1/2 - have you seen my posts 
to the xen-devel list recently?




As you can see, I'm making some progress but not completely there yet!

I think the next investigation is qemu-dm or the hvmloader, but I didn't write 
this stuff and I'm no expert by far! I've already emailed Ian Pratt to ask for 
his assistance...

Keep me posted on you progress!

Hi Tim,

I've been trying to port the vga passthrough code from XCI to Xen
unstable, unfortunately I'm getting error signal 7.

I think I'll try to compile XCI and give that a shot. I tried that
earlier, but had a hard time getting it to even build properly. Thus,
can I ask you for a summary of the steps you took to build it, or
perhaps the resources to do so?

What I did was to download all the sources (build, xen, kernel,
toolstack and ioemu) into one folder, and tried to build each component.
Unfortunately, the build is really unforgiving.

I'll appreciate your help and suggestions. If I'm able to build and test
it successfully, then at least we have one more test case.


Best Rgds,
Beng Heng, Ng
