The xenapi driver has not seen any development since its initial
contribution 9 years ago. There have been no bug reports, no patches,
and no queries about the driver on the developer or user mailing lists.
Remove the driver from the libvirt sources.

QEMU version 2.12.1 introduced a performance feature under commit
be7773268d98 ("target-i386: add KVM_HINTS_DEDICATED performance hint")
This patch adds a new KVM feature 'hint-dedicated' to set this performance
hint for KVM guests. The feature is off by default.
To enable this hint and have libvirt add "-cpu host,kvm-hint-dedicated=on"
to the QEMU command line, the following XML code needs to be added to the
guest's domain description in conjunction with CPU mode='host-passthrough'.
<features>
<kvm>
<hint-dedicated state='on'/>

Historically URIs handled by the remote driver will always connect to
the libvirtd UNIX socket. There will now be one daemon per driver, and
each of these has its own UNIX sockets to connect to.
It will still be possible to run the traditional monolithic libvirtd
though, which will have the original UNIX socket path.
In addition there is a virproxyd daemon that doesn't run any drivers,
but provides proxying for clients accessing libvirt over IP sockets, or
tunnelling to the legacy libvirtd UNIX socket path.
Finally when running inside a daemon, the remote driver must not reject
connections unconditionally. For example, the QEMU driver needs to be
able to connect to the network driver. The remote driver must thus be
willing to handle connections even when inside the daemon, provided no
local driver is registered.
This refactoring enables the remote driver to be able to connect to the
per-driver daemons. The URI parameter "mode" accepts the values "auto",
"direct" and "legacy" to control which daemons are connected to.
The client side libvirt.conf config file also supports a "remote_mode"
setting which is used if the URI parameter is not set.
If neither the config file or URI parameter set a mode, then "auto"
is used, whereby the client looks to see which sockets actually exist
right now.
The remote driver will only ever spawn the per-driver daemons, or
the legacy libvirtd. It won't ever try to spawn virtproxyd, as
that is only there for IP based connectivity, or for access from
legacy remote clients.
If connecting to a remote host over any kind of ssh tunnel, for now we
must assume only the legacy socket exists. A future patch will introduce
a netcat replacement that is tailored for libvirt to make remote
tunnelling easier.
The configure arg '--with-remote-default-mode=legacy|direct' allows
packagers to set a default at build time. If not given, it will default
to legacy mode.
Eventually the default will switch to direct mode. Distros can choose
to do the switch earlier if desired. The main blocker is testing and
suitable SELinux/AppArmor policies.

There is no restriction on maximum value of PCI domain. In fact,
Linux kernel uses plain atomic inc when assigning PCI domains:
drivers/pci/pci.c:static int pci_get_new_domain_nr(void)
drivers/pci/pci.c-{
drivers/pci/pci.c- return atomic_inc_return(&__domain_nr);
drivers/pci/pci.c-}
Of course, this function is called only if kernel was compiled
without PCI domain support or ACPI did not provide PCI domain.
However, QEMU still has the same restriction as us: in
set_pci_host_devaddr() QEMU checks if domain isn't greater than
0xffff. But one can argue that that's a QEMU limitation. We still
want to be able to cope with other hypervisors that don't have
this limitation (possibly).

Earlier patches mentioned that the initial implementation will prevent

However, the actual restriction is done in this separate patch to make
it easier to lift that restriction via a revert, when we are finally

Introduce a bunch of new public APIs related to backup checkpoints.
Checkpoints are modeled heavily after virDomainSnapshotPtr (both
represent a point in time of the guest), although a snapshot exists
with the intent of rolling back to that state, while a checkpoint
exists to make it possible to create an incremental backup at a later
time. We may have a future hypervisor that can completely manage
checkpoints without libvirt metadata, but the first two planned
hypervisors (qemu and test) both always use libvirt for tracking
metadata relations between checkpoints, so for now, I've deferred
the counterpart of virDomainSnapshotHasMetadata for a separate
API addition at a later date if there is ever a need for it.
Note that until we allow snapshots and checkpoints to exist
simultaneously on the same domain (although the actual prevention of
this will be in a separate patch for the sake of an easier revert down
the road), that it is not possible to branch out to create more than
one checkpoint child to a given parent, although it may become
possible later when we revert to a snapshot that coincides with a
checkpoint. This also means that for now, the decision of which
checkpoint becomes the parent of a newly created one is the only
checkpoint with no child (so while there are APIs for dealing with a
current snapshot, we do not need those for checkpoints). We may end
up exposing a notion of a current checkpoint later, but it's easier to
add stuff when proven needed than to blindly support it now and wish
we hadn't exposed it.
The following map shows the API relations to snapshots, with new APIs
on the right:
Operate on a domain object to create/redefine a child:
virDomainSnapshotCreateXML virDomainCheckpointCreateXML
Operate on a child object for lifetime management:
virDomainSnapshotDelete virDomainCheckpointDelete
virDomainSnapshotFree virDomainCheckpointFree
virDomainSnapshotRef virDomainCheckpointRef
Operate on a child object to learn more about it:
virDomainSnapshotGetXMLDesc virDomainCheckpointGetXMLDesc
virDomainSnapshotGetConnect virDomainCheckpointGetConnect
virDomainSnapshotGetDomain virDomainCheckpointGetDomain
virDomainSnapshotGetName virDomainCheckpiontGetName
virDomainSnapshotGetParent virDomainCheckpiontGetParent
virDomainSnapshotHasMetadata (deferred for later)
virDomainSnapshotIsCurrent (no counterpart, see note above)
Operate on a domain object to list all children:
virDomainSnapshotNum (no counterparts, these are the old
virDomainSnapshotListNames racy interfaces)
virDomainSnapshotListAllSnapshots virDomainListAllCheckpoints
Operate on a child object to list descendents:
virDomainSnapshotNumChildren (no counterparts, these are the old
virDomainSnapshotListChildrenNames racy interfaces)
virDomainSnapshotListAllChildren virDomainCheckpointListAllChildren
Operate on a domain to locate a particular child:
virDomainSnapshotLookupByName virDomainCheckpointLookupByName
virDomainSnapshotCurrent (no counterpart, see note above)
virDomainHasCurrentSnapshot (no counterpart, old racy interface)
Operate on a snapshot to roll back to earlier state:
virDomainSnapshotRevert (no counterpart, instead checkpoints
are used in incremental backups via
XML to virDomainBackupBegin)

Prepare for new checkpoint APIs by describing the XML that will
represent a checkpoint. The checkpoint XML is modeled heavily after
virDomainSnapshotPtr. See the docs for more details.
Add testsuite coverage for some minimal uses of the XML (bare minimum,
the sample from html, and a full dumpxml, and some counter-examples
that should fail schema validation). Although use of the REDEFINE flag
will require the <domain> subelement to be present, it is easier for
most of the tests to provide counterpart output produced with the
NO_DOMAIN flag (particularly since synthesizing a valid <domain>
during testing is not trivial).
