It's possible to share the same drives among multiple MVS and VM systems. We use VMTAPE, the z/OS's use ATAM. Our VM's SYSTEM CONFIG says DEVICES NOASSIGN_AT_IPL for the shared drives. If VMTAPE finds its drive choice "assigned elsewhere" (in use on z/OS or another VM) it tries another drive address until it finds one to ASSIGN and use.

You also need to ensure that MVS and VM don't concurrently use the same tape drives. I believe you'll either need to segregate the drives between your systems or invest in something like CA's MIM/VM.
