Dear QEMU Community, I am currently stuck with starting an Intel TDX VM on a compatible hardware (meaning that this machine has already successfully hosted an Intel td). When executing
qemu-system-x86_64 \ -enable-kvm \ -nographic \ -accel kvm \ -m 4G -smp 4 \ -name process=tdxvm,debug-threads=on \ -cpu host \ -object tdx-guest,id=tdx0 \ -machine q35,hpet=off,kernel_irqchip=split,confidential-guest-support=tdx0 \ -nographic -vga none \ -bios /usr/share/ovmf/OVMF.fd \ -kernel ./ubuntu-24.04-server-cloudimg-amd64-vmlinuz-generic \ -drive file=./ubuntu-24.04-server-cloudimg-amd64.img,if=virtio,format=qcow2,id=virtio-disk0 \ -serial stdio \ -nodefaults \ -device virtio-net-pci,netdev=nic0 -netdev user,id=nic0,hostfwd=tcp::10022-:22 \ -device virtio-blk-pci,drive=virtio-disk0 I get qemu-system-x86_64: -object tdx-guest,id=tdx0: Parameter 'qom-type' does not accept value 'tdx-guest‘ Can you please give me some hint, where I might have gone wrong and what to change? Best Regards Ricarda
