There is no problem running TSM in a VM, as Lindsay reported. There
are however limitations, for instance VMWare can't currently expose FC
HBA's or FC tape drives to a VM, so you can't use FC tape drives. IIRC
in xen this must be possible, because a domU can (but usually doesn't)
directly drive an HBA.

Quite a few organisations run TSM on a pSeries LPAR.

In all cases of course you must keep in mind that large TSM servers
doe a huge amount of I/O, require lots of memory and quite a bit of
CPU, making them not the best candidates for virtualization.
