exposing PCI devices to guest

exposing PCI devices to guest

[Gerry Reno]

I would like to expose some fxo PCI cards to my Asterisk guest under 
KVM.  How can I do this?  I see where maybe you can hotplug some nic | 
storage devices but what about other PCI devices like my fxo cards?  Is 
there some kernel line options that could do this?

Regards,
Gerry

Does KVM provide VT-D to allow u pass through your PCI device?

Thanks,
Neo

probably today we haven't the technology we are using!

Weidong,

Just curious, is it any estimation of this feature? when will it be available?

If I can get a draft version, that would be great. I want to play with it.

Thanks,
Neo

Re: exposing PCI devices to guest

[Han, Weidong]

Hi Neo,

Amit Shah is working on pci passthrough. The trees are: 
git-pull git://git.kernel.org/pub/scm/linux/kernel/git/amit/kvm.git 
git-pull
git://git.kernel.org/pub/scm/linux/kernel/git/amit/kvm-userspace.git

Allen Kay has sent out a set of patches to support VT-d a few days ago.
They are based on Amit's pci-passthrough tree. You can try them first.
