Text paste to guest without the Guest Additions

Postby isgdre » 16. Jul 2015, 21:03

Is there any way we can get Host Text Copy to Guest Paste without the Guest Additions installed?

This doesn't seem like a huge problem so I'm kind of wondering why virtualbox doesn't do it when other VMs do.

I assume you meant other Virtualization Programs/Hypervisors and not "VMs" VM = Virtual Machine.

There isn't a way, no, and I doubt there will be with the current structure of VirtualBox, so don't hold your breath.

Essentially, Virtualbox without Guest Additions gives you the equivalent of two or more real PCs side-by-side, using a KVM switch, possibly networked together if you set them up that way. How would you be able to cut on one PC and have the clipboard data from that one PC be available on another PC? Figure that out and you'd have your solution on how to do that in Virtualbox without Guest Additions. Clue: you're going to need some kind of installed program in each PC - they don't have such capability out of the box, as you know.

A quick Google on "share clipboard between computers" got me this blog: https://gigaom.com/2008/05/28/7-ways-to ... clipboard/ with seven add-on programs that do what you'd like - again, they're installs, not built-in.

So instead of installing the VirtualBox Guest Additions, you install what amounts to third party additions (which are not optimized for VirtualBox).

This makes me doubt the statement that other VM software can do this out of the box. Apart from kludgy keyboard hacks I don't see what mechanism could be used by any VM platform to copy data into a VM that isn't running some form of data receive app.

No, I don't want to have to install an additional program. I can't say I've looked at the code for other MVs but given how they react I would think that they added a bit to the keyboard driver and simulate the appropriate key press information via the PS/2 port.

Virtualbox already does this somewhat as it's is fully able to pass/block keyboard information into a mv without the Guest Additions. So we are talking about that code sometimes taking the input from a "paste buffer" instead of the host computer's keyboard.

This feature is fine to disable once Guest Additions are recognized.

Work has already started in that front. See also the discussion in Input -> Keyboard -> "Paste as text (send characters)". Not a lot has been done due to other priorities, but they know about that option.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
