Re: [HTCondor-users] VirtualBox: Guest user vs. Condor account!?!

The procedure to follow should be:

1. create a new virtual machine environment
2. attach the virtual disk (from the Condor file transfer) to the new virtual machine
3. start the virtual machine.

VBoxHeadless.exe cannot do steps 1 and 2, but that must be done with VBoxManage.exe.
This is also suggested on the VirtualBox website:


Hence: first use VBoxManage.exe to set everything up for the new VM,
and then use VBoxHeadless.exe to start the VM
(the options with VBoxHeadless.exe are limited to already created VMs).

This seems likely. vboxmanage.exe tries to open a window which won't
work if there is no desktop. Try using vboxheadless.exe to start the VM.
