VirtualBox Freezing

Postby bph » 14. Jun 2012, 09:45

I have an odd problem runnign VirtualBox

I had been using it successfully for several weeks running Windows7 64 bti VM on Ubuntu 11.10 Host

I then upgraded Host OS to Ubuntu 12.04 and broke VirtualBox I think due to kernel mismatch

My solution was to renistall the 12.04 (precise) .deb package from the virtualbox download site

This worked *during* the current session, i.e. while I was logged in to Ubuntu

However, closing down the machine then restarting ubuntu and then starting virtualbox was causing my machine to freeze completely

I then deleted the Windows VM uninstalled VirtualBox and reinstalled VirtualBox via the ubuntu software manager

I then reinstalled the Windows VM

Again, all worked fine *during* that session, but now, after closing down and rebooting, virtualbox freezes the machine every time

Has anyone experienced any similiar problems to this?

having done a little more digging, this bug seems to be very similar to what I am experiencing:

Ticket #10528 (new defect) <- sorry not allowed to post urls yet...

a further question would be how I can implement the fix? Does this imply I have to rebuild virtualbox from the latest svn src to fix the problem?

So far I have just been using the precompiled binaries from the download section, e.g. the precise .deb file

for now I have added:

nmi_watchdog=0 nowatchdog

to /etc/defult/grub, e.g.

Code: Select all   Expand viewCollapse view
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
# Uncomment for original line pre-virtualbox bug workaround (bph 20120614)
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nmi_watchdog=0 nowatchdog"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"




then re-ran update-grub, e.g.

Code: Select all   Expand viewCollapse view
$ sudo update-grub


touch-wood - this *seems* to have fixed the problem

I'll post the ticket URL here: https://www.virtualbox.org/ticket/10528

Yes, that certainly sounds like what you ran into, and the workaround given in the ticket should apply.

Thank you sooo much!
The bug is already fixed by the way in SVN (so maybe fixed with next release of VirtualBox).
