I would not expect so, as it is only virtualization? Is more about whether or not the OS supports thise with drivers?
Also to show what virtualization adds to the mix, size of virtual tapes was not actually linked or restricted to physical tape sizes, as backups would be written until they reached the end of (virtual) tape.
However we kept the size artificially smaller than the physical counterpart as when there was only a tiny bit of not-yet-expired data on it, all data on it, would not be able to become released yet on the DD end. Also had a daily relabel running of expired tapes, to help with getting expired data to be release don DD end, as only once a tape was relabeled, data on it actually got marked as expired on the DD...
