commit d4f40976d0d169c89abfa6f56574b496318061cc Author: Sean Mooney <[email protected]> Date: Wed Feb 5 20:31:31 2025 +0000 move nova-ovs-hybrid-plug to deploy with spice and fix qxl default In centos/rhel 9 qemu supprot for the qxl model was removed with the removal of spice support. In ubuntu 24.04 qemu support for qxl and spice supprot has now also been removed. debian 12 bookworm still support spice in there qemu package. When we updated the default video model to virtio for x86 we left a config driven special case for spice to default to qxl since that nolonger works on centos or ubuntu based distos that default is not helpful so this change removes the special case making virtio the default for x86 regardless of the console used. This change also updates the nova-ovs-hybrid-plug to test with spice so that we have at least one job using it. to enable that the job is moved to debian.
