Since upgrade to Ubuntu 16.04, VMs won't start

[flip]

Hi
I have been happily using VirtualBox to access my Windows7 and Windows XP VMs with Ubuntu 12.04 for many years. I finally bit the bullet and upgraded to 14.04 a couple of days ago and did some tests of all my apps (I think I recall) vbox worked OK. I then upgraded again to 16.04 yesterday and encountered the following problem when Starting either VM…
I get two (not one) Start VM dialogs
On one, progress was 0%
Other (Starting virtual machine 2/2) Progress goes to 20%
but both freeze.
Virtual Box Manager also freezes, so I either need to log out, or kill the vbox processes from a terminal.

Repeatable every time.

I am using VirtualBox Graphical User Interface Version 5.0.40_Ubuntu r115130

Linux mach-name 4.4.0-83-generic #106-Ubuntu SMP Mon Jun 26 17:54:43 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Looking on-line It seems to have something to do with Secure boot, so I created a signature, but to do this mokutil failed because ‘EFI variables are not supported on this system’. I suspect this is to do with LVM. Now the fix to this is to customise the kernel.

But in any case because I would be doing multiple layers of fixes, none of which I am confident will work, I am wondering is there anything else more straight-forward I can try to re-instate access to my Virtual Machines?

Attached is the vbox log.

Any help or advice would be greatly appreciated !

Regards,
Phil

Two problems.

• 1) you are running the ubuntu fork ( OSE ) that we do not support here.
  2) you have two extpacks installed, one is the distro fork that supports VNC and the second that is from VirtualBox that supports all of the features available. Problem is the VirtualBox extpack does not match the running version of VirtualBox.

Code: Select all
