A system at work said I did have the vmx flag (actually there is a

strange BIOS setting that would only take effect after a power cycle. So
not only do you need the chip support, you need a BIOS that allows you to
enable it (and the cpuinfo test won't check for that). I have heard
horror stories of BIOS version which refuse to offer the ability to enable
the feature (but never personally seen one), so merely checking vmx may
not be enough.
In fact the the kvm-intel module actually prints in the system
log something like "Virtualization support unavailable, disabled
by BIOS".
I don't know if the same applies to the AMD equivalent.
