I tend to believe there are more pre-HVM 64-bit guests than 32-bit
guests. 64-bit CPUs are mainstream for a few years and 32-bit-only
server systems are getting old. Almost everyone I know with 64-bit CPUs
prefers to run 64-bit Linux over 32-bit.
So, I think it is worth to support pre-HVM 64-bit guests.
Cheers,
Jan
