When starting a guest with TPM of type='emulator' an external process is started with it (swtpm) to emulate TPM. This external process is passed path to a log file via --logfile. The path to the log file is generated in qemuTPMEmulatorPrepareHost() which works, until the daemon is restarted. The problem is that the path is not stored in private data or anywhere inside live XML and thus later, when qemuExtTPMStop() is called (when shutting off the guest) the stored logpath is NULL and thus its seclabel is not cleaned up (see virSecuritySELinuxRestoreTPMLabels()). Fortunately, qemuExtDevicesStop() (which calls qemuExtTPMStop() eventually) does call qemuExtDevicesInitPaths() where the log path can be generated again. Basically, tpm->data.emulator.storagepath is generated in qemuExtTPMInitPaths() and its seclabels are restored properly, and this commit move logfile onto the same level. This means, that the log path doesn't have to be generated in qemuExtDevicesStart() because it was already done in qemuExtDevicesPrepareHost(). This change also renders @vmname argument of qemuTPMEmulatorPrepareHost() unused and thus is removed.

libvirt library code README
===========================
The directory provides the bulk of the libvirt codebase. Everything
except for the libvirtd daemon and client tools. The build uses a
large number of libtool convenience libraries - one for each child
directory, and then links them together for the final libvirt.so,
although some bits get linked directly to libvirtd daemon instead.
The files directly in this directory are supporting the public API
entry points & data structures.
There are two core shared modules to be aware of:
* util/ - a collection of shared APIs that can be used by any
code. This directory is always in the include path
for all things built
* conf/ - APIs for parsing / manipulating all the official XML
files used by the public API. This directory is only
in the include path for driver implementation modules
* vmx/ - VMware VMX config handling (used by esx/ and vmware/)
Then there are the hypervisor implementations:
* bhyve - bhyve - The BSD Hypervisor
* esx/ - VMware ESX and GSX support using vSphere API over SOAP
* hyperv/ - Microsoft Hyper-V support using WinRM
* lxc/ - Linux Native Containers
* openvz/ - OpenVZ containers using cli tools
* qemu/ - QEMU / KVM using qemu CLI/monitor
* remote/ - Generic libvirt native RPC client
* test/ - A "mock" driver for testing
* vbox/ - Virtual Box using native API
* vmware/ - VMware Workstation and Player using the vmrun tool
* xen/ - Xen using hypercalls, XenD SEXPR & XenStore
Finally some secondary drivers that are shared for several HVs.
Currently these are used by LXC, OpenVZ, QEMU and Xen drivers.
The ESX, Hyper-V, Remote, Test & VirtualBox drivers all
implement the secondary drivers directly
* cpu/ - CPU feature management
* interface/ - Host network interface management
* network/ - Virtual NAT networking
* nwfilter/ - Network traffic filtering rules
* node_device/ - Host device enumeration
* secret/ - Secret management
* security/ - Mandatory access control drivers
* storage/ - Storage management drivers
Since both the hypervisor and secondary drivers can be built as
dlopen()able modules, it is *FORBIDDEN* to have build dependencies
between these directories. Drivers are only allowed to depend on
the public API, and the internal APIs in the util/ and conf/
directories
