Is HT particularly worthwhile for virtualization loads? we have
several older servers which have ht and I found that when running
windows terminal services it actually slowed the machine down, and
under certain circumstances it seemed to cause the system to become
extremely slow and had to be rebooted, we disabled ht and the problem
went away.

Many documents on the web recommend disabling ht for specific
workloads, and most benchmarks show that when it is benificial the
performance gain is quite small.

Or is your plan to make use of ht in a way that gets the most benefit
with no impact under edge cases?

"New" HT, as reintroduced in i7, is supposed to be "much better".
