### Why is VT-x/AMD-V important?
Xen doesn't use VT-x/AMD-V for PV guest virtualization.
(It uses ring0/3 separation instead.)
However, without VT-x/AMD-V, you won't be able to use fully virtualized VMs (e.g., Windows-based qubes).
By default, Qubes uses Xen's PVH and HVM virtualization modes, which require VT-x/AMD-V.
This means that, without VT-x/AMD-V, no VMs will start in a default Qubes installation.
In addition, if your system lacks VT-x/AMD-V, then it also lacks VT-d/ADM-Vi/AMD IOMMU.
(See next question.)
