We've recently installed ESXi 4.1 on a couple of new R700s, and are also interested in
running OMSA on them, as we have the OMSA/Nagios tandem working extremely well on
several non-virtualhost machines.  Googling seems to bring up a number of posts on the
process of installing OMSA on ESXi, not the least of which is one from the Dell
TechCenter: (well,
OK, that's for ESX, but ...).  Another is:  Of course, your search
will find still more.

We've not tried any of these yet, so we can't vouch for their veracity.  Other posters
have suggested some interesting alternatives, though.
