Hi. If I move a slider to 2 CPUs in VM settings, it can't start with "verr_vmx_msr_locked_or_disabled"

The host is a desktop PC, not a laptop

Everest telss the following:

Code: Select all

MB: Intel Frostburg DG33FB
CPU:	Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz
Nested Paging	unsupported
Virtual Machine Extensions (Vanderpool)	supported
Virtual Mode Extension	supported
I don't have any virtualisation settings in BIOS

After I press OK and close the guest window, a separate process VirtualBox.exe stays running, and buttons on main window are grayed out. So I have to kill VirtualBox.exe via task manager

VBox has detected the VT-x enabled CPU but if your bios does not support hardware virtualization you can not set the processor count above 1
See if there is an update to your bios.

Your CPU and BIOS need to support hardware virtualisation (Intel VT-x or AMD-V) to be able to run 64bit guests or guests with more than one virtual CPU in VirtualBox.
