Hi all, I've just bought a new computer with a "Intel(R) Core(TM) i5-9600K CPU @ 3.70GHz" cpu. I have enabled VMX and VT-d in the "BIOS", but nvmm doesn't seem to work on it. It's not reported in the kernel boot messages; on my old computer it is. $ qemu-system-x86_64 -accel nvmm qemu-system-x86_64: -accel nvmm: NVMM: Initialization failed, error=6 qemu-system-x86_64: -accel nvmm: failed to initialize nvmm: Device not configured This is what cpuctl says about the CPU; which details should I look at? bash-5.1$ cpuctl identify 0 Cannot bind to target CPU.
