Hello there!
I faced strange bug(?) on Gentoo host after full system update.
VBOX unable to open window with existing VM. It was pretty OK before update.
Compilation from packages (Portage) going OK, without any problems.
I downloaded source and re-compiled manually (in /opt/VirtualBox folder)
The same issue was occur.
I am not pretty strong in programming, but seems there some error occur.
Please, help me - what need to do or just where to dig for root of reason?
My vbox.log is attached. Please feel free to push me in case to need provide more information.
Thank You very much!

Not VirtualBox (fork). Problems should be taken up with those responsible for the fork.

00:00:01.377735 VMSetError: The configuration constructor in main failed due to a COM error. Check the release log of the VM for further details.

I'd guess that it hasn't been installed correctly, or perhaps you updated the host kernel after the install.

If you want support here you should download and install the official release (see downloads area).
