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 (C) 2005-2010 Oracle Corporation All rights reserved.
