I am trying to get TPM 2.0 pass through to work with Xen and libvirt, but I can't get it to work.
According to the following sites both Xen and libirt have TPM 2.0 support.
https://wiki.xen.org/wiki/Virtual_Trusted_Platform_Module_(vTPM)
https://libvirt.org/formatdomain.html#elementsTpm
However, when I add a TPM device to a VM (by virt-manager), the VM guest XML does contain the TPM configuration, but the VM guest (linux) does not show any TPM device.

Also, when looking in /var/log/libvirt/libxl/vmguest.log there is no mention of tpm in the (converted libvirt XML to libxl) vm structure.
Is this because libvirt only supports TPM with QEMU?
If so, are there any development plans for TPM support with XEN?
Is there a workaround for the time being?
