right.  

alternatively, you might consider setting:

COUNT_HYPERTHREAD_CPUS = FALSE

that way, the multi-threading in the bios won't be counted towards
Condor VMs and you'll get 2 condor VMs on each dual-cpu machine.
then, as matt suggests, you could do fancy stuff with the policy
expressions for the 2 VMs to suit your needs while there are
interactive users, but still get twice the throughput when the machine
is totally idle...

ugh...  unfortunately, i just discovered that this setting only works
on Linux. :(  at the very least, it should be documented as such.
furthermore, i just created an internal bug report so our windows and
porting experts can try to get this working on other platforms.

for anyone on the list (or scanning the archives) who has the same
question but is using linux, this is good info on how to solve it.
