[Users] Intel VT-x and openVZ/virtuozzo 7 CPU virtu technology

[Jehan Procaccia]

I am trying to install virtuozzo OS (3515) on a dell R610 model, it 
warns at the very begining of the install process with
"environement not fully supported virtualization technology"
Although I did enable Virtualization in the bios !
is my CPU really uncompatible with virtuozzo 7 ?
If I want to run only Containers (CT) and no KVM on that host , will it 
work anyway ?
by the way CT a based on which technology (openvz 6 legacy "cgroups" or 
LXC, or something else ... ) ?

here is my CPU/hardware:
