FWIW I have 64-bit guests working fine on my still-9-current (r225756) amd64 host with the latest ports vbox. I'm running it with the gui in X, not sure if that makes a difference.

I don't think so, my equivalent lines are identical to yours except that I have and SMX in Features2 which seems to be a "safe mode" extension. > Is this a case of, unbeknownst to me, it isn't enabled in the BIOS? This is (unfortunately) likely. The relevant stuff wasn't enabled in mine by default. Also, the name for the option may not be straightforward. On my Dell the option is called VMM, Virtual Machine Monitor. I had to do a bit of trial and error before I found the right knob. > This is a remote > server, so a quick reboot / check isn't the easiest to do, so would > alike to confirm before I go down that route … can someone that does > have 64bit guests working check their CPU Features and let me know if > I am missing that Feature here? :( hth, Doug -- Nothin' ever doesn't change, but nothin' changes much. -- OK Go Breadth of IT experience, and depth of knowledge in the DNS.
