Is there > a trick to enable it? Bisection qemu-kvm userspace is tricky. The upstream qemu repo (git://git.qemu.org/qemu.git) does not have PCI device assignment support. The qemu-kvm repo does regular merges w/ the upstream qemu repo. As you bisect through the qemu-kvm repo history, you are likely to land on a commit that is from upstream (meaning a tree w/out downstream qemu-kvm additions, like device assignment). Depending on where you suspect the issue is coming from, you can be careful to bisect only through the qemu-kvm tree (by skipping back to a merge point), or you can remerge the qemu-kvm tree to the qemu tree when you bisect into the qemu tree. Note...gfx assignment has many issues associated w/ it and often does not work. You can check out Allen Kay's presentation at the recent KVM Forum for some examples: http://goo.gl/Hyk13 thanks, -chris -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
