Description of problem: When running instack-setup-host on a RHEL 7 machine you fail with a qemu error: Created machine instack with UUID 448eefe9-ffc1-46c2-99db-e698441d9e36 + virsh start instack error: Failed to start domain instack error: unsupported configuration: SATA is not supported with this QEMU binary How reproducible: 100% Steps to Reproduce: 1. Install accordint to the instructions of TripleO, but run instack-setup-host (from https://raw.githubusercontent.com/hardys/spinalstack-env/master/instack-setup-host) instead of instack-virt-setup Actual results: The instack VM can't start
This problem happens from time to time, also with TripleO and not just instack. Reprovisioning the host solves this. It is not clear why it keeps happening randomly.
This issue has resurfaced in the latest poodles and puddles. poodle = 6.0/2015-02-16.3 It seems to be repeatable, we're unable to launch guests w/ the latest builds Last known good version is puddle 2015-01-20.1 \
Possible workaround rm -Rf /var/cache/libvirt/qemu/capabilities/ service libvirtd restart
