Before the fix:

[rhel.virtual_devices.tpm_device.negative_test.emulator.encryption_test.none_pw]
Expect should succeed, but got: 

error: Failed to define domain from /var/tmp/xml_utils_temp_5a8z71gm.xml
error: unsupported configuration: The QEMU executable /usr/libexec/qemu-kvm does not support TPM model tpm-crb
