This needs to be submitted for all branches 5.15+ So a test confirming that it has somehow been exercised on 6.6 (we can skip 6.1 runtime testing) is required.
We also should really renamed the fragment to "kvm-host", since I've never liked the existing name .. but this is used in places in throughout the meta-data as a KERNEL_FEATURE, so changing it isn't trivial .. let's not to that change for now, but I'll consider it in the future. If you can submit a v2 showing 5.15 and 6.6 testing I can merge the change.
