I am on master and I didn't revert the "Dynamic sized kvm memslots array"
series, which we know has benefits for other VM configs and workloads.

For testing purposing, we could add a toggle defining a constant number of
memslots maybe ? and 0 would mean grow-on-demand ?

I didn't look at performance yet and downtime with mlx5 VFs was not a
big issue either. So I am expecting QE to share test results with vGPUs
under load.

Thanks,
