XENPVH (``xenpvh``)
=========================================
This machine creates a IOREQ server to register/connect with Xen Hypervisor.
When TPM is enabled, this machine also creates a tpm-tis-device at a user input
tpm base address, adds a TPM emulator and connects to a swtpm application
running on host machine via chardev socket. This enables xenpvh to support TPM
functionalities for a guest domain.
More information about TPM use and installing swtpm linux application can be
found at: docs/specs/tpm.rst.
Example for starting swtpm on host machine:
.. code-block:: console
mkdir /tmp/vtpm2
swtpm socket --tpmstate dir=/tmp/vtpm2 \
--ctrl type=unixio,path=/tmp/vtpm2/swtpm-sock &
Sample QEMU xenpvh commands for running and connecting with Xen:
.. code-block:: console
qemu-system-aarch64 -xen-domid 1 \
-chardev socket,id=libxl-cmd,path=qmp-libxl-1,server=on,wait=off \
-mon chardev=libxl-cmd,mode=control \
-chardev socket,id=libxenstat-cmd,path=qmp-libxenstat-1,server=on,wait=off \
-mon chardev=libxenstat-cmd,mode=control \
-xen-attach -name guest0 -vnc none -display none -nographic \
-machine xenpvh -m 1301 \
-chardev socket,id=chrtpm,path=tmp/vtpm2/swtpm-sock \
-tpmdev emulator,id=tpm0,chardev=chrtpm -machine tpm-base-addr=0x0C000000
In above QEMU command, last two lines are for connecting xenpvh QEMU to swtpm
via chardev socket.
