Add a new machine xenpvh which creates a IOREQ server to register/connect with
Xen Hypervisor.
Optional: When CONFIG_TPM is enabled, it also creates a tpm-tis-device, adds a
TPM emulator and connects to swtpm running on host machine via chardev socket
and support TPM functionalities for a guest domain.
Extra command line for aarch64 xenpvh QEMU to connect to swtpm:
-chardev socket,id=chrtpm,path=/tmp/myvtpm2/swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm \
-machine tpm-base-addr=0x0c000000 \
swtpm implements a TPM software emulator(TPM 1.2 & TPM 2) built on libtpms and
provides access to TPM functionality over socket, chardev and CUSE interface.
Github repo:https://github.com/stefanberger/swtpm
Example for starting swtpm on host machine:
mkdir /tmp/vtpm2
swtpm socket --tpmstate dir=/tmp/vtpm2 \
--ctrl type=unixio,path=/tmp/vtpm2/swtpm-sock &
