Check for KVM_CAP_ADJUST_CLOCK capability KVM_CLOCK_TSC_STABLE, which indicates that KVM_GET_CLOCK returns a value as seen by the guest at that moment. For new machine types, use this value rather than reading from guest memory. This reduces kvmclock difference on migration from 5s to 0.1s (when max_downtime == 5s).
