Hello,
I have a new Installation of Mountain Lion with the 10.8.2 patch. No other Vitualisation tools are installed
When I try to start a Windows 8 guest I have this error:
./VBoxManage startvm windows
Waiting for VM "windows" to power on...
VBoxManage: error: VT-x is being used by another hypervisor. (VERR_VMX_IN_VMX_ROOT_MODE).
VBoxManage: error: VirtualBox can't operate in VMX root mode. Please close all other virtualization programs. (VERR_VMX_IN_VMX_ROOT_MODE)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component Console, interface IConsole
Thanks,
JB
