qemu_tpm: Generate log file path among with storage path
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().

virhostdev.c: remove missing PCI devs from hostdev manager
virHostdevReAttachPCIDevices() is called when we want to re-attach
a list of hostdevs back to the host, either on the shutdown path or
via a 'virsh detach-device' call. This function always count on the
existence of the device in the host to work, but this can lead to
problems. For example, a SR-IOV device can be removed via an admin
"echo 0 > /sys/bus/pci/devices/<addr>/sriov_numvfs", making the kernel
fire up and eventfd_signal() to the process, asking for the process to
release the device. The result might vary depending on the device driver
and OS/arch, but two possible outcomes are:
1) the hypervisor driver will detach the device from the VM, issuing a
delete event to Libvirt. This can be observed in QEMU;
2) the 'echo 0 > ...' will hang waiting for the device to be unplugged.
This means that the VM process failed/refused to release the hostdev back
to the host, and the hostdev will be detached during VM shutdown.
Today we don't behave well for both cases. We'll fail to remove the PCI device
reference from mgr->activePCIHostdevs and mgr->inactivePCIHostdevs because
we rely on the existence of the PCI device conf file in the sysfs. Attempting
to re-utilize the same device (assuming it is now present back in the host)
can result in an error like this:
$ ./run tools/virsh start vm1-sriov --console
error: Failed to start domain vm1-sriov
error: Requested operation is not valid: PCI device 0000:01:00.2 is in use by driver QEMU, domain vm1-sriov
For (1), a VM destroy/start cycle is needed to re-use the VF in the guest.
For (2), the effect is more nefarious, requiring a Libvirtd daemon restart
to use the VF again in any guest.
We can make it a bit better by checking, during virHostdevReAttachPCIDevices(),
if there is any missing PCI device that will be left behind in activePCIHostdevs
and inactivePCIHostdevs lists. Remove any missing device found from both lists,
unconditionally, matching the current state of the host. This change affects
the code path in (1) (processDeviceDeletedEvent into qemuDomainRemoveDevice, all
the way back to qemuHostdevReAttachPCIDevices) and also in (b) (qemuProcessStop
into qemuHostdevReAttachDomainDevices).
NB: Although this patch enables the possibility of 'outside Libvirt' SR-IOV
hotunplug of PCI devices, if the hypervisor and the PCI driver copes with it,
our goal is to mitigate what it is still considered a user oopsie. For all
supported purposes, the admin must remove the SR-IOV VFs from all running domains
before removing the VFs from the host.

virhostdev.c: virHostdevGetPCIHostDevice() now reports missing device
Gitlab issue #72 [1] reports that removing SR-IOVs VFs before
removing the devices from the running domains can have strange
consequences. QEMU might be able to hotunplug the device inside the
guest, but Libvirt will not be aware of that, and then the guest is
now inconsistent with the domain definition.
There's also the possibility of the VFs removal not succeeding
while the domain is running but then, as soon as the domain
is shutdown, all the VFs are removed. Libvirt can't handle
the removal of the PCI devices while trying to reattach the
hostdevs, and the Libvirt daemon can be left in an inconsistent
state (see [2]).
This patch starts to address the issue related in Gitlab #72, most
notably the issue described in [2]. When shutting down a domain
with SR-IOV hostdevs that got missing, virHostdevReAttachPCIDevices()
is failing the whole process and failing to reattach all the
PCI devices, including the ones that aren't related to the VFs that
went missing. Let's make it more resilient with host changes by
changing virHostdevGetPCIHostDevice() to return an exclusive error
code '-2' for this case. virHostdevGetPCIHostDeviceList() can then
tell when virHostdevGetPCIHostDevice() failed to find the PCI
device of a hostdev and continue to make the list of PCI devices.
virHostdevReAttachPCIDevices() will now be able to proceed reattaching
all other valid PCI devices, at least. The 'ghost hostdevs' will be
handled later on.
We're going to add logic to handle the case where a previously
existing PCI device does not longer exist in the host.
The logic was copied from virPCIDeviceNew(), which verifies if a
PCI device exists in the host, returning NULL and throwing an
error if it doesn't. The NULL is used for other errors as well
(product/vendor id read errors, dev id overflow), meaning that we
can't re-use virPCIDeviceNew() for the purpose of detecting
if the device exists.
