From: Pauline Middelink To: kvm@vger.kernel.org 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.
