On the VM, upon  boot I receive

event 32 - the drive detected that the device \device\harddisk0\DR0 has write cache enabled.  Data corruption may occur.

How where do you address this with Virtual disks?

You don't. This is something you change on the physical storage where the virtual disks are stored. The hypervisor is capable of detecting the status and capabilities of the underlying physical storage and will bubble up misconfiguration issues such as this as events into the guest VMs.

This error is not happening on the hypervisor.

Of course not. The hypervisor can use disks with a write cache for a variety of reasons. So it has nothing to complain about. But that cache can cause VHD corruption, so the guest will complain of its VHD is on such a disk. This is expected behavior.
