[dave3112]

Hey,
i want to record my virtual machine, but VirtualBox don't create a output.
I installed the guest addition CD and the VirtualBox Extension Pack for version 5.2.18.

I try to record while running the vm and from beginn. I create a file with touch test.webm and start recording again.
I changed the path to a other hdd...

VirtualBox dont popup any errors.

I don't have a other idea.

Host System: Ubuntu 64 Bit - 18.10
Guest System: Ubuntu 64 Bit - 18.04

Do you have a idea?

Thanks for helping

version 5.2.18

That's old, please upgrade. Preferably to 6.0.10.

I create a file with touch test.webm

Why? VirtualBox will create it for you, you don't have to "touch" anything, literally and figuratively.
