I just converted one of my hosts to Mint 18 and am running VM tasks on a Linux host for the first time. I found it easy to install VBox 5.1.10 and the extension pack, and have successfully completed several (LHC Theory) tasks with no apparent problem.

It's not a big deal (I don't think) but running VM jobs are not being displayed in the VBox manager as they are in my Win10 hosts. I've also noticed that when a VM job is selected on the "Tasks" tab of the BOINC manager (7.6.31), the "Show Graphics" button is grayed out and the "Show VM Console" is not listed on the lefthand side under "Commands".

I don't recall having to do anything under Windows for the VBox install and am wondering if there's another step or if there's a problem somewhere.

Thanks for any advice.

Cheers

...running VM jobs are not being displayed in the VBox manager as they are in my Win10 hosts.

From a similar thread in a project forum, another user noted:

BOINC in Linux uses separate account, so you need to run VboxManager under "boinc" username.
It's kinda like 
$ sudo su -s /bin/sh -c VirtualBox boinc

That does indeed fix the issue with the VBox manager; however, it doesn't seem to help with the missing graphics and VM console features in the BOINC manager.
