Host: Ubuntu 16.04 LTS / VirtualBox 5.1.2 r108956
Guest: Ubuntu 16.04 LTS or Windows 7 Professional

Dear Community,

after upgrade to latest version my guests aren't starting any more (see screenshot). I'm not sure what to do.
Can someone help me please??

Thanks a lot,

Was the host upgraded from a previous version of Ubuntu or a clean install?
Was VirtualBox an upgrade from a previous version that did work?
Was the original VirtualBox the Ubuntu fork and if so did you purge that install before installing 5.1.*?

Hi Perryg,

thanks for your answer. I've started "dpkg -l" and removed everything regarding virtualbox, and installed v5.21 again.

Now my Ubuntu-Guest works, but the Windows-Guest get's the error from screenshot ... (xml also attached ...)

Thank you

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

Thanks for help

Did you originally have the Extension Pack installed?

[kangaroo72]

yep - it's installed (5.2.1) 5.0.18 before

[Perryg]

Code: Select all

00:00:00.187779 Installed Extension Packs:
00:00:00.187788   None installed!

You sure about that?

[kangaroo72]

huh?? That's bad ...

can I fix this??

[Perryg]

Sure. Download the matching Extension Pack and install it.

[kangaroo72]

I thought I did this?? It's shown in virtualbox manager (the extpack). Do I have to install it on console??

[Perryg]

Run the following in the host terminal and post the results

Code: Select all

VBoxManage list extpacks

[kangaroo72]

Code: Select all

tescher@SV-SYDNEY:/$ VBoxManage list extpacks

actual log ...

[Perryg]

This log looks a lot better and shows the ExtPack and the availability for EHCI so far so good. Now do you still get the same error message when you start the guest? It does not show in the log file.
