Since the topic was brought up, I have a long going request that oVirt will enable users to run multiple machine type versions on the same host (using the same qemu binary but providing a different -M compatibility level per VM).
Is that on the roadmap?
I assume once will start with cluster level enumeration/monitoring first which is the bug which i asked to open around this thread. then look at per vm level (I'm guessing best way to make this easy to manage at per-vm level would be to use 'cluster default' for most vm's) I understand choosing cpu model per vm may (mainly for -cpu best) also be desirable in some cases.
Cpu model is a VM property. Setting anything beyond the least common denominator of your set of hardware hosts, may restrict using some of the older hosts as expected. btw: -cpu best is less flexible for non homogeneous set of hosts. Better use an explicit model for such environment. In theory the newest models should perform just as good as -best
