    Ubuntu crashes on running VirtualBox

    Hi all,

    I am on Ubuntu 12.04. I just started using virtualbox at work (on win7) and now I wish to run virtualbox on my home PC (running Ubuntu). However, my computer crashes every time when I start running a guest OS using VirtualBox. Anyone knows how to fix it? Please indicate what information I need to provide in order to get this problem fixed since I'm pretty much a n00b...

    EDIT: The version of my VirtualBox on Ubuntu is 4.1.12_Ubuntur77245

    Many thanks!

    Re: Ubuntu crashes on running VirtualBox

    I'm going to start with this for you to try:

    1. open a terminal window
    2. type "sudo gedit /etc/default/grub" (without the quotes) and press enter
    3. Comment out the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" by adding a "#" character in front.
    4. Add new line below: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nmi_watchdog=0 nowatchdog"
    5. Save and exit
    6. type "sudo update-grub" (without the quotes) and press enter
    7. reboot.

    The potential workarounds can be found here.

    How did you install it? What installation document did you follow? And what are your computer specifications?

    Daslinkard,

    Thank you so much for your help and sorry for my late reply. I forgot to subscribe to this thread and so thought nobody had replied

    I tried the steps you suggested, but with no luck. I'll read the workaround your posted and post the results here later.

    Re: Ubuntu crashes on running VirtualBox

    How much RAM do you have, and how much RAM have you given the guest OS? VirtualBox requires a lot of RAM, and your computer may crash if the RAM runs out.

    4GB, and I have only assigned 1GB to my VirtualBox GuestOS, so I don't think that is the problem.

    Thanks!
