The Owner attribute only appears in job ads, and shows the user who  
submitted the job.

Adding extra attributes in the config file doesn't make them appear  
in the machine ad. You have to use STARTD_EXPRS to tell Condor what  
extra attributes to include. You don't need to include the extra  
attributes for RANK to work though, because you're using config file  
substitution to build the expression. As you see, the final result in  
the machine ad is this:

Rank = (10 * (Owner == "rfinch")) - LoadAvg - (3 * ((KeyboardIdle <  
1.500000 * 60 * 60) && (VirtualMachineID == 1))) + 5.000000

Another option would be to include the extra attributes in the  
machine ad and have Rank refer to them in the ad. You would set your  
config file like this:

MachineOwner = "rfinch"
SelfMachine = (10 * (Owner == MachineOwner))
# Current Virtual Machine load
VMLoad = LoadAvg
# redefine keyboard busy to be within 90 minutes
KeyboardBusy = (KeyboardIdle < 1.5 * 60 * $(MINUTE))
# Don't want to use both VMs if keyboard is busy; don't use 1st VM
MachineBusy = (3 * ($(KeyboardBusy) && (VirtualMachineID == 1)))
# Machine ranking
RANK = SelfMachine - VMLoad - MachineBusy + 5.0
# Inlcude the extra attributes in the machine ad
STARTD_EXPRS = $ 
(STARTD_EXPRS),MachineOwner,SelfMachine,VMLoad,MachineBusy

Then the machine would have these attributes:

MachineOwner = "rfinch"
SelfMachine = (10 * (Owner == MachineOwner))
VMLoad = LoadAvg
MachineBusy = (3 * ((KeyboardIdle < 1.5 * 60 * 60) &&  
(VirtualMachineID == 1)))
Rank = SelfMachine - VMLoad - MachineBusy + 5.0

So, when constructing expressions that will appear in the machine ad,  
you can have the attribute references resolved when the config file  
is read (by using the $(...) notation) or in the machine ad itself.  
In the latter case, you have to ensure that the attributes make it  
into the ad.
