vm-type X86_TDX_VM not supported by KVM (Ubuntu 22.04)

[Eggwane]

Hi,

I followed all the instructions of the build/ubuntu-22.04/ README.md and got everything well built but then I'm getting this error while running the command ./start-qemu.sh -i td-guest-ubuntu-22.04.qcow2 -b grub .

qemu-system-x86_64: -accel kvm: vm-type X86_TDX_VM not supported by KVM

I tried to change the path of the qemu binary in order to use the one I built : QEMU_EXEC="~/projects/tdx-tools/build/ubuntu-22.04/intel-mvp-tdx-qemu-kvm/mvp-tdx-qemu-v7.2.0/b/qemu/qemu-system-x86_64" but the error remains.

Am I not using the good KVM stack somehow? The lsmod command shows that the kvm and kvm_intel modules are loaded though.

Thanks in advance for your help.

Ok my bad, I thought it was a repo for simulation but apparently there's no way to get any hardware nor simulation like we could with SGX as mentioned in #86 and #249.
