This patch adds support for an external swtpm TPM emulator. The XML for
this type of TPM looks as follows:
<tpm model='tpm-tis'>
<backend type='emulator'/>
</tpm>
The XML will currently only start a TPM 1.2.
Upon first start, libvirt will run `swtpm_setup`, which will simulate the
manufacturing of a TPM and create certificates for it and write them into
NVRAM locations of the emulated TPM.
After that libvirt starts the swtpm TPM emulator using the `swtpm` executable.
Once the VM terminates, libvirt uses the swtpm_ioctl executable to gracefully
shut down the `swtpm` in case it is still running (QEMU did not send shutdown)
or clean up the socket file.
The above mentioned executables must be found in the PATH.
The executables can either be run as root or started as root and switch to
the tss user. The requirement for the tss user comes through 'tcsd', which
is used for the simulation of the manufacturing. Which user is used can be
configured through qemu.conf. By default 'tss' is used.
The swtpm writes out state into files. The state is kept in /var/lib/libvirt/swtpm:
[root@localhost libvirt]# ls -lZ | grep swtpm
drwx--x--x. 7 root root unconfined_u:object_r:virt_var_lib_t:s0 4096 Apr 5 16:22 swtpm
The directory /var/lib/libvirt/swtpm maintains per-TPM state directories.
(Using the uuid of the VM for that since the name can change per VM renaming but
we need a stable directory name.)

certificates for the device.
Further, the external TPM needs storage on the host that we need to set
up before it can be run. We can clean up the host once the domain is
undefined.
This patch also implements a small layer for external device support that
calls into the TPM device layer if a domain has an attached TPM. This is

This patch adds support for an external swtpm TPM emulator. The XML for
this type of TPM looks as follows:
<tpm model='tpm-tis'>
<backend type='emulator'/>
</tpm>
The XML will currently only define a TPM 1.2.
Extend the documentation.
Add a test case testing the XML parser and formatter.
