The semantics of the backup operation don't strictly require that all
disks being backed up are part of the same incremental part (when a disk
was checkpointed/backed up separately or in a different VM), or even
they may not have a previous checkpoint at all (e.g. when the disk
was freshly hotplugged to the vm).
In such cases we can still create a common checkpoint for all of them
and backup differences according to configuration.
This patch adds a per-disk configuration of the checkpoint to do the
incremental backup from via the 'incremental' attribute and allows
perform full backups via the 'backupmode' attribute.
Note that no changes to the qemu driver are necessary to take advantage
of this as we already obey the per-disk 'incremental' field.

QEMU 4.1.0 introduced a new device type called TPM Proxy, currently
implemented by PPC64 guests via a new virtual device called
'spapr-tpm-proxy' (see QEMU 0fb6bd073230 for more info).
The TPM Proxy device interacts with a TPM Resource Manager, a host
device capable of multiplexing the host TPM with multiple processes.
This allows multiple guests to access some TPM features at the
same time. Note that this mode of operation does not provide
full TPM features to be available for the guest - for that case
the guest still needs to assign a vTPM device (tpm-spapr for
PPC64 guests). Although redundant, there is currently no technical
limitation for a guest to assign both a vTPM and a TPM Proxy at the
same time.
This patch adds documentation and schema for a new TPM model
type called 'spapr-tpm-proxy' that creates this new TPM Proxy
device. This model is valid only for the 'passthrough' backend.
An example of a TPM Proxy device connected to a TPM Resource Manager
'/dev/tpmrm0' will look like this:
<tpm model='spapr-tpm-proxy'>
<backend type='passthrough'>
<device path='/dev/tpmrm0'/>
</backend>

On Linux, changing the nodeset on 'numatune' does not imply that
the guest memory will be migrated on the spot to the new nodeset.
The memory migration is tied on guest usage of the memory pages,
and an idle guest will take longer to have its memory migrated
to the new nodeset.
This is a behavior explained in detail in the Linux kernel
documentation in Documentation/admin-guide/cgroup-v1/cpusets.rst.
The user doesn't need this level of detail though - just needs
his/her expectations under check. Running 'numastat' and hoping
for instant memory migration from the previous nodeset to the new
one is not viable.
There's also parts of the memory that are locked by QEMU in the
same place, e.g. when VFIO devices are present. Let's also
mention it as another factor that impacts the results the
user might expect from NUMA memory migration with numatune.

In formatdomain, using 'libxl' and 'xen' is redundant since they now
both refer to the same driver. 'xen' predates 'libxl' and unambiguously
identifies the Xen hypervisor, so drop the use of 'libxl'.
In aclpolkit, the connection URI was erroneously identified as 'libxl'
and the name 'xenlight'. Change the URI to 'xen' and driver name to 'Xen'.

This patch adds the implementation of the IBS pSeries feature,
using the QEMU_CAPS_MACHINE_PSERIES_CAP_IBS capability added
in the previous patch.
IBS can have the following values: "broken", "workaround",
"fixed-ibs", "fixed-ccd" and "fixed-na".
This is the XML format for the cap:
<features>
<ibs value='fixed-ibs'/>

using the QEMU_CAPS_MACHINE_PSERIES_CAP_SBBC capability added
in the previous patch.
Like the previously added CFPC feature, SBBC can have the values
"broken", "workaround" or "fixed". Extra code is required to handle
it since it's not a regular tristate capability.

If an user is trying to configure a dhcp neetwork settings, it is not
possible to change the leasetime of a range or a host entry. This is
available using dnsmasq extra options, but they are associated with
dhcp-range or dhcp-hosts fields. This patch implements a leasetime for
range and hosts tags. They can be defined under that settings:
<dhcp>
<range ...>
<lease/>
</range>
<host ...>

'passthrough' is Xen-Specific guest configuration option new to Xen 4.13
that enables IOMMU mappings for a guest and hence whether it supports PCI
passthrough. The default is disabled. See the xl.cfg(5) man page and
xen.git commit babde47a3fe for more details.
The default state of disabled prevents hotlugging PCI devices. However,
if the guest configuration contains a PCI passthrough device at time of
creation, libxl will automatically enable 'passthrough' and subsequent
hotplugging of PCI devices will also be possible. It is not possible to
unconditionally enable 'passthrough' since it would introduce a migration
incompatibility due to guest ABI change. Instead, introduce another Xen
hypervisor feature that can be used to enable guest PCI passthrough
<features>
<xen>
<passthrough state='on'/>
</xen>
</features>
To allow finer control over how IOMMU maps to guest P2M table, the
passthrough element also supports a 'mode' attribute with values
restricted to snyc_pt and share_pt, similar to xl.cfg(5) 'passthrough'
setting .

e820_host is a Xen-specific option, only available for PV domains, that
provides the domain a virtual e820 memory map based on the host one. It
is enabled with a new Xen hypervisor feature, e.g.
<features>
<xen>
<e820_host state='on'/>
</xen>
</features>
e820_host is required when using PCI passthrough and is generally
considered safe for any PV kernel. e820_host is silently ignored if set
in HVM domain configuration. See xl.cfg(5) man page in the Xen
documentation for more details.
