Josh,

Thanks for the quick fix. I have installed the patch.

I submitted a new block reservation and this time it allocated all 16 machines, 
didn't get any errors.

Thanks,
Mike

Mike,

See if the attached patch fixes the problem.  This is an issue I caught in our
production install but didn't get the fix pushed in to the code repository.

If you put the file in /tmp and then cd to the .ht-inc directory of your
install, you can use the following command to apply the patch:

patch < /tmp/vmhostcheck_fix.patch

You don't need to restart anything after applying the patch.  utils.php is the
only file it will modify.  It's always a good idea to make a backup copy of a
file before applying a patch.
