#36910: Virtualbox @4.2.4 +vde2+vnc won't start VMs
--------------------------+--------------------------------

     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.1.2
 Keywords:                |       Port:  virtualbox
--------------------------+--------------------------------
 After upgrading port virtualbox to @4.2.4 it cannot start any VM on my
 10.7 system with XCode 4.5.1, trying to do so shows a dialog containing
 the following error:
 {{{
 Failed to open a session for the virtual machine Arch.

 Failed to load VMMR0.r0 (VERR_GENERAL_FAILURE).

 Result Code: NS_ERROR_FAILURE (0x80004005)
 Component: Console
 Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}
 }}}

 The error happens at an early stage of the VM starting and it's not
 dependent on the guest OS.
 The launchd item and kexts have been correctly unloaded and reloaded.

 Switching back to @4.2.2 reverts the behavior to a correct start of the
 VMs.

 I'd like to get feedback from VBox's users to check if this issue is
 related to system or Xcode version.
