We IPL our VM natively in an LPAR instead of using the DR vendor's VM "floor system". Depending on one's full volume backup/restore product, you have a number of choices. If you're a z/OS shop too, you have that entire infrastructure to work with. I've used HiDRO, Dynam-B and Syback, both IPL'ed from tape or restored to the vendor's floor system to rebuild my VM system. Currently we have a high availability remote copy strategy (EMC SRDF/A, IBM has a similar but different product), so that our data is already there and we just IPL our 530RES pointed at a DR system config and merged "DR" directory that contains the system images (CMS, Linux and TPF) that we're interested in recovering.

After much research and discussion it was determined 'virtualization' beyond the 2nd level is not going to preform well. I believe thats what Rob is explaining. This year we ran our linux guest on their VM system. Ran GREAT! I believe there was a presentation at SHARE in Aug on this very topic.
