Hello, When I try to run the TDX guest image, It failed with the following message:
'virtio-9p-pci' is not a valid device model name

test machine:

• CPU：INTEL(R) XEON(R) GOLD 6530
• GPU：NVIDIA GeForce RTX 4090D
• OS: centos 7.x
• qemu 8.2.50

I update the qemu, but it still failed. The new error is qemu-system-x86_64: -object tdx-guest,id=tdx: Parameter 'qom-type' does not accept value 'tdx-guest'

Please follow the configuration guide at https://github.com/canonical/tdx to set up your host system and install the compatible QEMU version.

OK，I will try, thanks.

@kvinwang But the os is centos7, does it matter?

I don't believe CentOS is supported. The host system configuration remains complex even with Ubuntu 24.x. You're likely to encounter difficulties despite following the Canonical/TDX guide.

OK, thanks. This comment shows how to install TDX on centos.
