Dear David J. Herzfeld,
Thank you for your suggestion to manipulate the VirtualBox environment variables to more sensible values.
I searched internet and found conflicting methods how to do this.
Some people say, just set it with the 'set' command, like I did below.
Others seem to recommend using instead: "My Computer->Properties->Advanced->Environment Variables".
The last one writes into the registry, which I think might not work for an unprivileged Condor user .....??
So just for testing, I used the following DOS batch script and submitted it to Condor:
REM start of DOS batch script: virtualbox.bat
echo VBOX_USER_HOME = %VBOX_USER_HOME%
echo ALLUSERSPROFILE = %ALLUSERSPROFILE%
echo USERPROFILE = %USERPROFILE%
echo HOMEDRIVE = %HOMEDRIVE%
echo HOMEPATH = %HOMEPATH%
echo USERDOMAIN = %USERDOMAIN%
echo USERNAME = %USERNAME%
echo APPDATA = %APPDATA%
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" list ostypes
REM end of DOS batch script
# Submit Description File
universe = vanilla
requirements = (target.Arch == "INTEL") && (target.OpSys == "WINNT51")
load_profile = True
executable = virtualbox.bat
when_to_transfer_output = on_exit
output = $(CLUSTER)_$(PROCESS).out
log = $(CLUSTER)_$(PROCESS).log
error = $(CLUSTER)_$(PROCESS).err
# end of Submit Description File
The output file has following 8 lines:
VBOX_USER_HOME = D:\condor\execute\dir_2560\
ALLUSERSPROFILE = C:\Documents and Settings\All Users
USERPROFILE = C:\Documents and Settings\condor-reuse-slot1
USERDOMAIN = SKKU-EJNMGFFR
USERNAME = condor-reuse-slot1
The error file has following 3 lines:
VBoxManage.exe: error: Failed to create the VirtualBox object!
VBoxManage.exe: error: Code CO_E_SERVER_EXEC_FAILURE (0x80080005) - Server execution failed (extended info not available)
VBoxManage.exe: error: Most likely, the VirtualBox COM server is not running or failed to start.
Alas, still the same error.
Note that HOMEDRIVE, HOMEPATH, and APPDATA are all empty variables for the unprivileged Condor user.....
Does that ring some bells?

It's been awhile since I used VirtualBox on Windows (and certainly
longer since I installed Condor on a Windows machine) - so take this
advice with a grain of salt.
Based on my experience with Pools of VirtualBoxes, I don't believe that
you will need to allow the Condor service to interact with the desktop.
We are able to start virtual machines in Vista/7 without a login
Note, however, that just about all VirtualBox commands require access to
the standard settings folder (on Windows this is in %HOMEDRIVE%%HOMEPATH
%), which is used to store the configuration of your created machines.
If the settings folder does not exist, then it will attempt to create
one. It may be the case that %HOMEDRIVE%%HOMEPATH% is unavailable on the
Condor account (or you are incapable of writing to that directory).
VirtualBox allows you to explicitly define the folder you wish to use
via the VBOX_USER_HOME environment variable. It may be worth adding
something like set VBOX_USER_HOME=%CD% to the start of your batch file.
