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
