"VBoxManage controlvm $name savestate" failes with "NS_ERROR_INVALID_ARG"

[Martin]

Hi,

Basic info:

Host	32-bit Debian Linux, Dell Precision M4500. Virtualbox 3.2.10
Guest	Win7 (32bit).

Problem: I try to save the state of my running guest from terminal because my X server screwed up (which might be another bug). I googled out that by calling

VBoxManage controlvm Win7 savestate

I should be able to save the state of the running VM. When I issue the command I get the following response:

mnt@localhost:~$ VBoxManage -nologo list runningvms
"Win7" {e7f536be-16f6-4a98-b3cb-cd8939917b58}
mnt@localhost:~$ VBoxManage controlvm Win7 savestate
Oracle VM VirtualBox Command Line Management Interface Version 3.2.10_OSE

ERROR: code NS_ERROR_INVALID_ARG (0x80070057) - Invalid argument value (extended info not available)
Context: "SaveState(progress.asOutParam())" at line 165 of file VBoxManageControlVM.cpp

The outcome of the command is that the Virtual Machine is shut down instead of the state is saved.

Please reopen if still relevant with VBox 3.2.12 / 4.0.2. Can't reproduce this here.
