It seems that re-entering virtualized execution on UD interception gives the user the flexibility of running binaries with newer instructions on older hardware, if kvm is able to emulate the newer instructions. I do not fully understand the details of this scenario, is there such a scenario or is it likely that ud_interception() will change?
Yes, you are correct. This emulation capability is used in some cases, including: MOVBE, SYSCALL/SYSENTER on 32-bit guests, VMCALL and VMMCALL.
