error running a VirtualBox image: E_FAIL 0x80004005

unknown error creating VM: VERR_VMX_MSR_LOCKED_OR_DISABLED
Component: Console

Interface :
   

IConsole {515e8e8d-f932-4d8e-9f32-79a52aead882}


0x80004005 is a Windows error meaning "unspecified error"




Reducing the Virtual Machine memory to less than 4GB seems to fix the problem...

now I get FATAL: No bootable medium found! System halted.
