Set up a VM which uses a differencing disk as its boot disk, and the differencing disk points to a parent disk on a network share. Ran SSA against the VM.

I can see us calling .DriveType() to check if the disk is a network disk or not, and then using elevated access to read the VM's parent disk:

But non-elevated access on the local VM disk:
