Qemu is latest from master branch.
Tryingto start a domain, which is connected toa blankcdrom:
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw'/>
<target dev='sdb' bus='scsi'/>
<readonly/>
<address type='drive' controller='0' target='1'
bus='0' unit='0'/>
</disk>
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.
