Guest = Kubuntu 8.04
This guest OS worked on this host last week.
I turned it on today and first got an error about VRDP, which I worked around by setting it to port 3391. (I don't think I changed Vista's Remote Desktop settings since last week, but, anyway...)
Now I'm getting the following error as soon as I start the guest OS:
Note: VTX is disabled in the Advanced Settings.VirtualBox can't operate in VMX root mode.
VBox status code: -4011 (VERR_VMX_IN_VMX_ROOT_MODE).
Result Code:
