When you control your own hypervisor, you are aware of the features you are using, since you have configured the system and the VMs. However, if you are using a service provider for your hosting or cloud, you need to do some detective work to determine the hypervisor mode and features employed.
MODE DETECTION
From dmesg:
[ 0.000000] Hypervisor detected: Xen HVM
Indicates that the VM is either HVM or PVHVM.
