UPS Shuts down Hyper Visor, but will it shutdown gracefully the running VM's ?

I just purchased a CyperPower UPS and attached it to my Del T110 so it will shutdown the Hypervisor after 5 mins of losing power. But what about the running VM's? Will they all gracefully shutdown and will they just TURN OFF?

I am running Windows Server 2012 R2 standard on a Dell T110 32 gb 2 nics
