The TPM Proxy connects to a TPM Resource Manager + present in the host, enabling the guest to run in secure virtual + machine mode with the help of an Ultravisor. Adding a TPM Proxy to + a pSeries guest brings no security benefits unless the guest is + running on a PPC64 host that has Ultravisor and TPM Resource Manager + support. Only one TPM Proxy is allowed per guest. A guest using + a TPM Proxy device can instantiate another TPM device at the same + time. This device is supported only for pSeries guests via the new + 'spapr-tpm-proxy' model of the TPM 'passthrough' backend. + * **Improvements** * **Bug fixes**
