HW-assisted virtualization from Ring 3

Post by randoll »

Does HW-virtualization support virtual machines spawning from ring 3 programs without ring 0 support code? I looked into manuals and it looks like all AMD-V and Intel VT-x instructions are ring 0 only.

You need kernel support and help to do recursive hardware-accelerated visualization. On Linux, this is implemented through technologies such as KVM.
