[VBox-users] Third try for answers: Why VBoxManager cannot list vms

[Harry P. <re...@ne...>]

I've attempted to get some help on this twice before recently.  I got
one replay informing me that the posting user could run VBoxManager
from cygwin shell and successfully `list vms'

Is there no one here who has an idea how to debug this?
Is the content of my posts too lame to deserve attention?

My setup must be very similar to the one reply I got about cygwin:

Lan with linux and windows7 machines,  One windows7 machine has 2 vms
installed from Vbox.  Both are running some kind of solaris guests.
That win7 box also has cygwin installed.

My usage usually would be to ssh into the windows box, which puts me
in a cygwin shell.  

   echo $SHELL
  /bin/bash

And cygwin bash is the only one installed.

And `which VboxManage' shows:
   which VboxManage
  /cygdrive/c/Program Files/Oracle/VirtualBox/VboxManage

I think I've updated twice.. and now running:

   VboxManage -v
   4.1.6r74713

These commands (below) used to get the expected responses... 

In that shell the command `VboxManage list vms' pauses a moment and
then returns me to the shell prompt... no output.

Something like `VboxManage startvm voi', returns output that seems to
indicate that VboxManage does not know anything about any vms
installed and seems to indicate there is some registering process.

Ditto for VboxManage list -l runningvms
  Again no output at all, even though two vms are currently running

Is it possible to re-register or whatever, the installed vms so that
VboxManage knows about them

  VboxManage startvm voi
  VboxManage.exe: error: Could not find a registered machine named 'voi'

  VboxManage.exe: error: Details: code VBOX_E_OBJECT_NOT_FOUND
 (0x80bb0001), component VirtualBox, interface IVirtualBox, callee
 IUnknown Context: "FindMachine(Bstr(pszVM).raw(),
 machine.asOutParam())" at line 544 of file VBoxManageMisc.cpp

The VboxManage tool is so involved its not so easy to see how to get
some better debug information or how to debug this situation.
