Hi, I pulled latest git yesterday and noticed that graphics card pass through does not work anymore. The VM hangs (probably when initializing the gfx card) when passing a graphics card to the VM. I started to do a git bisect but device assignment does not work at all when doing it. I started like this: cd /usr/local/src git clone git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git qemu-kvm-2011-08-12 cd qemu-kvm-2011-08-12 git bisect start git bisect good fda19064e889d4419dd3dc69ca8e6e7a1535fdf5 git bisect bad 44755ea36fee3f0b1093ef27404def8857602274 Bisecting: 229 revisions left to test after this [55c0975c5b358e948b9ae7bd7b07eff92508e756] Do constant folding for shift operations. ./configure --audio-drv-list=alsa --target-list=x86_64-softmmu --enable-kvm-device-assignment ERROR: unknown option --enable-kvm-device-assignment What am I doing wrong?
I continued with "git bisect bad" from this point on, but up to where I started, no revision supported device assignment.
I then did a "git bisect reset" and started over again. Now I continued with a few "git bisect good" until a revision came up that supported device assignment, but then after compiling and running qemu-system-x86_64, it exited with a segmentation fault. I continued with "git bisect good" until the end but all revision supporting device assignment existed with a segmentation fault.
How come so many revision do not support device assignment? Is there a trick to enable it?
Any help in this matter is greatly appreciated. Regards André -- 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
