Also implement functions to use swtpm_setup, which simulates the manufacturing of a TPM, which includes creation of 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 the layer we will wire up later on.

The XML for this type of TPM looks as follows: 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` executab= le. Once the VM terminates, libvirt uses the swtpm_ioctl executable to graceful= ly shut down the `swtpm` in case it is still running (QEMU did not send shutdo= wn) 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/libvir= t/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 renamin= g but we need a stable directory name.)
