Hi

My VirtualBox image crashes with when allocated more than 4GB base memory. Please help, details below:

• 1. Successfully deployed a VirtualBox image with no errors and the following settings:
  - base memory(3.584GB)
  - Enable PAE/NX = Y
  - hwvirtex = off (to resolve startup error "VT-x is not available. (VERR_VMX_NO_VMX)" when base memory is increased above 4GB)
  - network = NAT
  2. Increased the base memory to 12GB, and started image. However when trying to run any process the VirtualBox image crashes with error "Not in text mode"
  - Log file attached
  3. Environment details:
  - host: Windows Server 2008 R2 (64-bit)
  - guest: Oracle Linux 5 (32-bit)
  - virtualbox: 4.2.1 r80956

Thanks in advance,
Andrzej

[mod edit] For future reference, you wouldn't have needed to edit and split your log file attachment(s) if you uploaded it as a zip. I did it for you this time.

To run a 64bit guest, you need VT-x (if not available you get the "no VTx-x" error), however VT-x can only be used if nothing else is using it - otherwise you get the "VMX locked" error. I'm not sure if assigning more than 4GB to a guest requires VT-x support... but I wouldn't be surprised.

ps. "Not in text mode" is not an error message, it's just a statement of fact. The error recording feature tried to grab the blue/blackscreen information you sometimes get from the text mode shell (of some OS's) on a crash, but it couldn't because there was no shell.
