[Users] Good enough for KVM but not for OpenVZ 7?

I have a Dell PowerEdge R710 rack mount server. It is a few years old and it has an Intel Xeon E5530 @ 2.40GHz. KVM likes it just fine and it passes a virt-host-validate with flying colors but OpenVZ 7's vmxcap says:
Unrestricted guest no
Looking that up I find:
"VMX Unrestricted Guest is an Intel microprocessor feature that is also called IA-32e mode. Running a VM in this mode requires minimal involvement from software. You can think of it as running a VM bare-metal with its own EPT. This feature is available only on Westmere processors and later."
I ended up installing CentOS 7 on it and KVM works fine.
What's the deal? Why this extra restriction? :(
