VBoxManage does not see VMs

[spectroman]

Using the latest Linux 4.2.4 r81684, I was trying to use:

root@apophis:~# VBoxManage bandwidthctl "dc8af638-248c-4b2b-806a-40558e017114" set Limit --limit 1G
VBoxManage: error: Could not find a registered machine with UUID {dc8af638-248c-4b2b-806a-40558e017114}
VBoxManage: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBox, interface IVirtualBox, callee nsISupports
VBoxManage: error: Context: "FindMachine(Bstr(a->argv[0]).raw(), machine.asOutParam())" at line 309 of file VBoxManageBandwidthControl.cpp

While I can see:

root@apophis:~# ps aux | grep -i virtualbox
1000     11116  0.2  0.0   9512  4176 ?        S    09:35   0:18 /opt/VirtualBox/VBoxXPCOMIPCD
1000     11121  0.2  0.0  24304 12268 ?        Sl   09:35   0:18 /opt/VirtualBox/VBoxSVC --auto-shutdown
1000     12571  0.7  0.4 123788 59336 ?        Sl   10:39   0:30 /opt/VirtualBox/VirtualBox

If I use the name "XO3b" I get the same result.

Then I realized that "VBoxManage list vms" or anything that would consult or use a VMname name or UUID does not work.

As I already searched in the forums and here, I could only find a similar problem with no apparent solution.

So I can only see this as a bug. Let me know if I am wrong.
