WHen rebooting my windows xp virtualbox VM, the screen goes blank with the top 1/2 of the screen having slanted lines all over it.

it only seems to happen if I reboot and minimize the window, if I keep the focus on that window it doesn't happend.

I have to go to machines -> reset to fix it.

what host os? and which version of virtualbox do you use? – mihi Aug 24 '09 at 16:43

There are usually a few solutions for the screen hanging on a reboot:

  • Give the guest a little more memory
  • Disable Nested Paging in settings
  • Disable Auto resize guest display in settings

The slanted lines are likely from the auto resizing of the display.

what is nested paging? – user3183 Aug 24 '09 at 16:51
It is specific to AMD-V and Core i7, so it may not be of interest to you depending on what processor you have. – John T Aug 24 '09 at 16:58
