How reproducible:
100%

Steps to reproduce
1. Boot a TDX guest.
/usr/libexec/qemu-kvm \
-name tdxvm,process=tdxvm,debug-threads=on \
-accel kvm \
-smp 2 -m 4G \
-object '{"qom-type":"tdx-guest","id":"tdx","quote-generation-socket":{"type":"unix", "path": "/run/tdx-qgs/qgs.socket" }}' \
-monitor telnet:127.0.0.1:45454,nowait,server \
-bios /usr/share/edk2/ovmf/OVMF.inteltdx.fd \
-cpu host \
-nodefaults -nographic \
-vga none \
-machine q35,kernel_irqchip=split,confidential-guest-support=tdx,hpet=off \
-drive file=/home/kvm_autotest_root/images/rhel970-64-virtio-ovmf.qcow2,if=none,id=virtio-disk0 \
-device virtio-blk-pci,drive=virtio-disk0 \
device virtio-net-pci,netdev=nic0 -netdev user,id=nic0,hostfwd=tcp::10022:22 \
-serial stdio \

2. Check guest dmesg:
