Qemu is latest from master branch. Tryingto start a domain, which is connected toa blankcdrom:

But I get an error:
qemu-system-x86_64: -drive if=none,id=drive-scsi0-0-1-0,readonly=on,format=raw: Can't use 'raw' as a block driver for the protocol level.
Mathieu hit the same problem with a QEMU 2.6 backport for Debian jessie. His libvirt version is based on 1.2.9. QEMU began printing this error starting from version 2.6.0. I think newer libvirt versions have compensated. There is no error when I use Mathieu's domain XML with libvirt based on 1.3.3 (Fedora 24). Looks like you need a modern libvirt to run against a modern QEMU. Stefan
