VBoxManage raises Error getting stdout handle: VERR_NOT_IMPLEMENTED when piping

[tmassarini]

When running the following command I get the following error:

Command: VBoxManage guestcontrol vm_name run --exe /bin/ls --timeout 10000 --verbose --wait-stdout -- | grep -i 'home'

Error: VBoxManage: warning: Error getting stdout handle: VERR_NOT_IMPLEMENTED

When not piping everything seems to work fine. I can also redirect output to a file.

Same here. Can reproduce on VirtualBox 5.0.0 and 5.0.2 on OS X 10.10.5.

Same applies to standard error.

Workaround (for some cases) is to send stdout to a file and stderr to another file.

The issue should be fixed with VirtualBox 5.0.4. Does this work for you now?

[declassified]

No, not fixed with VirtualBox 5.0.4 on OS X 10.10.4. For me, it only happens when I run VBoxManage from a Python or Haskell program. When I run it from the terminal, it works fine.

declassified, are you sure that you are using the 5.0.4 Guest Additions?
