Useful mainly for migration. cpuUpdate changes guest CPU requirements in the following way:
- match == "strict" || match == "exact" - optional features which are supported by host CPU are changed into required features - optional features which are not supported by host CPU are disabled - all other features remain untouched - match == "minimum" - match is changed into "exact" - optional features and all features not mentioned in guest CPU specification which are supported by host CPU become required features - other optional features are disabled - oll other features remain untouched
This ensures that no feature will suddenly disappear from the guest after migration.
