Kernel panic when starting 2nd VM in VBox with VT-X enabled

Reported by: lid Owned by:
Priority: major Component: VMM/HWACCM
Version: VirtualBox 2.1.0 Keywords: panic, crash
Cc: Guest type: Linux
Host type: Mac OS X

Description (last modified by frank) (diff)

A kernel panic reproducibly occurs on a Mac OS X 10.5.5 host under the following conditions:

  1. A VM is already running in VMware Fusion 2.0.1.
  2. A VM is VT-X enabled is started in VBox 2.1.0.

The panic occurs before the VirtualBox splash screen shows in the VM window, I think. The panic does not occur when VT-X is disabled in VBox.
