Public bug reported: I have Ubuntu Precise Pangolin 32 bit, on a cpu that supports 64 bit, too.
If I run a 64 bit version of Ubuntu inside VirtualBox OSE 4.1.12, the host system hangs; no key combination works, the only way to gain control is to press the reset button. A workaround is to disable nmi watchdog, as described here: https://www.virtualbox.org/ticket/10528#comment:6 In file /etc/default/grub, put the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nmi_watchdog=0 nowatchdog" This will allow VirtualBox to work correctly. Since the bug has already been reported and fixed in newer version of VirtualBox (https://www.virtualbox.org/changeset/41645/vbox ), maybe a simple upgrade could fix it in Ubuntu Precise Pangolin. ** Affects: virtualbox (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1078790 Title: Virtualbox OSE crashes in Precise Pangolin if I try to run a 64 bit guest OS in a 32 bit host To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1078790/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
