Goal

RHEL has provided an easier "host-model" based automatic tuning option for Hyper-V enlightenments, which can greatly simplify Windows VM definitions and user experience and ensure that VMs are tuned for best performance.

User Stories

• As a cluster administrator, I want to see simplified Windows VM definitions.
• As a VM user, I want all Hyper-V tunings applied for best workload performance, with the correct options automatically configured depending on the host CPU model.

Non-Requirements

• Support for kernels older than 9.6 are not required
