When userspace reset the guest without notifying kvm, the CMMA state of the pages might be unused, resulting in guest data corruption. To avoid this, CMMA must be enabled only if userspace understands the implications. CMMA must be enabled before vCPU creation. It can't be switched off once enabled. All subsequently created vCPUs will be enabled for CMMA according to the CMMA state of the VM.
