[I know this is probably too late for 6.1 but maybe the first patch of the series is good as it just adds a missing doc?]
By default, KVM doesn't limit the usage of paravirtualized feature (neither native KVM nor Hyper-V) to what was exposed to the guest in CPUIDs making it possible to use all of them. KVM_CAP_HYPERV_ENFORCE_CPUID and KVM_CAP_ENFORCE_PV_FEATURE_CPUID features were recently introduced making it possible to limit available features to what was actually exposed. Add support for these to QEMU. While on it, document all currently supported KVM PV features in docs/kvm-pv.txt.
