It apparently IS possible to dedicate a device to more than one guest (tricksy, it is). While doing some IOCP research, I came across this in the description of the CNTLUNIT statement for IOCP: "When you are running VM with guest operating systems, you can use multiple CNTLUNIT statements for a single physical control unit in certain environments to effectively dedicate the same physical devices to more than one guest. This technique involves potential path-grouping considerations that create operational complications. Ensure you have determined possible consequences and that you use caution if employing this technique." Caveat emptor.
