Complete freeze

[nucknem]

Hello ! I need your help.
Every time I start a virtual machine my entire computer freezes and I have to turn it of by pushing the power button. I had absolutely no problems yesterday, and at first I thought my problem was genymotion (Android emulator that uses virtualbox to work) but no, my other machines do the same thing. I have looked at the logfiles but they are completely empty, I assume it's because I have to force my computer to turn off every time, the only thing I have is the genymotion log. I'm on Linux Mint and I'm using Virtualbox 5.0.40_Ubuntu r115130.

Genymotion log (Uploaded here because the file is too big for this forum):

Did you have any USB devices attached to VM? I ran into a similar problem - Ticket #17114 in vbox bugzilla

Just my mouse, but this has never caused a problem before.

You're using the Ubuntu's fork version of VirtualBox. You can either ask in their forums for help, or completely remove/uninstall/delete/purge their version and install the official version from the Downloads section of VirtualBox (https://www.virtualbox.org/wiki/Downloads).

Same thing for Genymotion...

I do have same problem, is there any solution yet?

We're going to need to see a VM log from a complete VM run:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM.
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).

I do had same problem, but it is gone now. what i did is just uninstalled it, removed completely using "apt-get autoremove/purge VirtualBox" then downloaded from official page instead of install from ubuntu appstore and installed it now it's back on track again.....
