#9168 closed defect (fixed)

OSX host system lockup when starting Win7 guest with Ubuntu guest already running

Reported by: tony19 Owned by:
Component: other Version: VirtualBox 4.0.8
Keywords: Cc:
Guest type: Windows Host type: Mac OS X

Description (last modified by Frank Mehnert)

Mac OSX (10.6.7) freezes when I try to start my Windows 7 guest while my Ubuntu guest is running. The system freezes when "Starting Windows" appears. The only resolution is to press and hold power button to shutdown and restart.

Please reopen if still relevant with VBox 4.1.22.

I think it had to do with lack of RAM. I had only 4G of RAM, 2G was in use by one of the VMs on top of that used by the host. My Windows VM required 2G. After I upgraded my system to 16GB of RAM, the problem went away.
