Recording video by using VBoxManage doesn't work for several reasons: 1. The options shown in the help screen (VBoxManage --help) don't exist and aren't accepted by VBoxManage (eg. ""--recording filename""). 2. By playing with spelling variants of the options I figured out, that eg. ""--recordingfile"" is accepted by VBoxManage. 3. In my tests I used the options like in the following example: VBoxManage modifyvm ""myVM"" --recording on --recordingfile=""/tmp/test.webm"" --recordingvideores=""1024x756"" --recordingvideorate=1024 --recordingvideofps=25 After modifying a (turned off) VM with these options the following happens: a. The VM will crash on next start attempt. This can only be fixed by turning off recording (VBoxManage modifyvm ""myVM"" --recording off). b. The CPU will jump to 100% for a few seconds. c. All VMs aren't available via the VBox GUI. Something like ""No information available"" is shown where the VM settings are shown usually. Maybe there are combinations of options that enable recording, but I couldn't find any. Thank you for your previous work on VirtualBox :-) Hauke",defect,closed,other,VirtualBox 6.0.4,fixed,VBoxManage recording capture,,other,other
