Subject: kvm-85 won't boot guests with virtio block device

Hi,

To follow up on the issues with kvm-85 and libvirt I discovered the following

issue: libvirt detects from the help of qemu which options it can give to

qemu. (in this case obviously /usr/kvm/bin/qemu-system-x86_64 -help)

If you look carefully to the output of the -help of qemu from kvm-84 and

kvm-85, you will notice the boot flag to the -drive option has disappeared!

Hence letting libvirt believe it isnt allowed to use it, hence the unable

to boot error.

A small patch which fixes the problem for me, is attached.

    Met vriendelijke groet,

        Pauline Middelink
