Firewire Support for KVM Guest?

Firewire Support for KVM Guest?

[Calin Brabandt]

I'm a KVM newb and can't find any information or
associated FAQ about KVM guest firewire support.  If
there's no KVM support, I'm seeking alternative
recommendations, if KVM list members are so inclined.

My goal is to boot a dedicated and proprietary Linux
2.4 kernel based AVX1 LiveCD under KVM.  See
http://www.169time.com/ for details, if interested.

Unfortunately, the AVX1 CD source is not available.
(Is this a GPL violation, perhaps?)

Normally the AVX1 CD must run on a standalone PC
equipped with two firewire ports for I/O.  The sole
function of AVX1 is to process firewire HDTV video
data but it can't decode, render, or record the video
data in any manner.

I'd like to run the AVX1 CD under a KVM on my Fedora 7
Mythtv system and loop the AVX1 firewire output back
into a third firewire port that's assigned to the
Mythtv host for capture.  I've booted both the AVX1 CD
disc and an iso image under KVM, but it hangs when it
tries to load the AVX1 guest firewire driver modules.

I have an Intel G965OT mobo with 2GB of DDR-2 and a
6600 Core 2 Duo.  I'll soon upgrade to 4GB of DDR-2
and a Q6600 quad CPU.  I don't believe the AVX1 CD
supports the TI firewire chip on my mobo so I
installed an AVX1 supported VIA chip firewire PCI card
that previously functioned correctly in my standalone
AVX1 system.

Any ideas, encouragement (or discouragement ;)) are
much appreciated.  If I can get this to work, there
are many 169time/AVX1 users at www.avsforum.com who
would be interested.  The 169time developer has
promised "integrated" support for years but, in
reality, I suspect he's completely abandoned the
project.

Thanks for everyone's patience, given that
knowledgeable KVM list readers may immediately
identify my goal as unrealistic folly.

-Cal

Possibily, but IANAL. You can report this to the GPL Violations
Mailing Lists if you think this might be the case
(http://gpl-violations.org/)

At the moment it seems that there's no support in qemu hence no
support in kvm. You can try the qemu mailing list and ask if someone
is working on this/if this is feasible.
