I rebooted one of my other 64bit servers, same motherboard, and found = that the Virtualization was disabled =85 unfortunately, my remote = console for the server I'm trying this isn't working for the keyboard, = so am going to need to get a local tech to fix this, but this seems like = the cause =85 checking VBox.Log, I'm also finding: pluto# grep VT VBox.log 00:00:00.281 HWACCM: No VT-x or AMD-V CPU extension found.
