This bug also affects me. I've tried installing virtual book versions 4.1.12, 4.1.18, 4.1.22, and 4.2. They have all caused a sudden system reboot wile installing or starting a VM. I've tried disabling 2d and 3d, not using usb, not using extensions or additions.
I am installing from amd64 host to x86 XP guest. I have finally got it to work. after Ubuntu Server upgrade to 12.10 from 12.04 i installed Virtualbox 4.1.18 with extentions and it crashed again. I was using the nvidaia-current driver. i changed to the open xorg driver and i have been able to install and run virtualbox VMs without it crashing. Seems to be a nvidia issue. I cant use the new desktop enviornment with the nvidia driver disabled. Has anyone found a soluiton to this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1004597 Title: Sudden hard reset (reboot) caused by VirtualBox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1004597/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
