this is a well known problem

you need VT-x enabled in the BIOS and after change this
you need a *hard* power cycle, means complete power off
and power on again - a reboot is not enough

without hardware virtualization you can not run x86_64 guests

where is this useless output from?
Xeon can be anything and nothing
"cat /proc/cpuinfo" is your friend

"Intel® Virtualization Technology (VT-x)" is the relevant thing you search
