Ah, I see the option now, which appears to be on by default. The test VM I just set up (a clean install from ubuntu-gnome-16.04-desktop-amd64.iso) doesn't copy or paste from host to guest or vice versa. I would be happy to log an issue in Github, is there any debug info I should provide?
I reached out to get their unreleased fix for this, after combing through the knowledgebase[1] and it works! Overall it performs a little better than Virtualbox in general for me, so far.
Could very well have been a factor. I gave up on it quickly. Repeatedly crashing renders it an unnecessary annoyance. VirtualBox works well enough, is stable and reliable, and Veertu doesn't distinguish itself enough to merit the pain in switching.
It's about time, Veertu has been using a lot of LGPL code without attribution or any visible attempts to comply with LGPL license requirements for the many components used.
Hopefully you guys did a true clean room implementation of the GPL components of QEMU.
