5.7.2.2 Supported paths for fallback migration of Integrity VM guests
Fallback migration of Integrity VM guests from the current VSP to a destination is supported only
if there is a supported path for online forward migration from the VSP where the guest was originally
booted on to the intended destination of fallback migration.
For more information about supported paths for online forward migration of Integrity VM guests,
see Section 5.7.2.1 (page 40).
5.7.2.3 Processor compatibility for online migration of Integrity VM guests
Online forward and fallback migration of Integrity VM guests are supported only if processors on
both source and destination VSPs are within supported Intel® Itanium® processor family groups
as given in Table 6 (page 41).
