Add a new machine xenpv 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 xenpv QEMU to connect to swtpm: -chardev socket,id=chrtpm,path=/tmp/myvtpm2/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ 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 & /* Comment about machine name. Will be removed in next version*/ Please reply with the machine name you agree. Below are two possible names: 1. xenpv 2. xenpvh
Please us xenpvh, as on Arm the guests are more like PVH guests. This will be needed on x86 to support e.g. virtio for PVH guests, and xenpv is already taken on x86 for PV guests. Juergen
