virt-xml-validate fails when run on a domain XML file of type 'vbox'.
For failing test case, see https://bugzilla.redhat.com/show_bug.cgi?id=757097
This patch updates the XML schema to accept all valid hypervisor
types, as well as dropping hypervisor types that are not in use
by the current code base.

To make lxcSetContainerResources smaller, pull the mem tune
and device ACL setup code out into separate methods
* src/lxc/lxc_controller.c: Introduce lxcSetContainerMemTune
and lxcSetContainerDeviceACL
While LXC does not have the concept of VCPUS, so we can't do
per-VCPU pCPU placement, we can support the VM level CPU
placement. Todo this simply set the CPU affinity of the LXC
controller at startup. All child processes will inherit this
affinity.
* src/lxc/lxc_controller.c: Set process affinity
This partly reverts my previous patch f88de3eb. We need to
get file status after open, as given path could have been symlink,
so fstat() will operate on different file than lstat().
When aligning you need to clear the bits in the mask and leave the
others aside. Likely this code has never run, and will never run.

One of my latest patches 2e37bf42d2
copy serial console definition. On domain shutdown we save this
info into state XML. However, later on the daemon start we simply
drop this info and since we are not re-reading qemu log,
vm->def->consoles[0] does not get populated with copy. Therefore
we need to avoid dropping console definition if it is just alias
for serial console.
If a connection to destination host is lost during peer-to-peer
migration (because keepalive protocol timed out), we won't be able to
finish the migration and it doesn't make sense to wait for qemu to
transmit all data. This patch automatically cancels such migration
without waiting for virDomainAbortJob to be called.
This API can be used to check if the socket associated with
virConnectPtr is still open or it was closed (probably because keepalive
protocol timed out). If there the connection is local (i.e., no socket
is associated with the connection, it is trivially always alive.
virConnectSetKeepAlive public API can be used by a client connecting to
remote server to start using keepalive protocol. The API is handled
directly by remote driver and not transmitted over the wire to the
server.
The keepalive program has two procedures: PING, and PONG.
Both are used only in asynchronous messages and the sender doesn't wait
for any reply. However, the party which receives PING messages is
supposed to react by sending PONG message the other party, but no
explicit binding between PING and PONG messages is made. For backward
compatibility neither server nor client are allowed to send keepalive
messages before checking that remote party supports them.
When virNetClientIOEventLoop is called for a non-blocking call and not
even a single byte can be sent from this call without blocking, we
properly reported that to the caller which properly frees the call. But
we never removed the call from a call queue.
If something fails while initializing qemu job object in
qemuDomainObjPrivateAlloc(), memory to the private pointer is freed, but
after that, the pointer is still dereferenced, which may result in a
segfault.
* qemuDomainObjPrivateAlloc() - Don't dereference NULL pointer.
Generally, functions which return malloc'd strings should be typed
as 'char *', not 'const char *', to make it obvious that the caller
is responsible to free things. free(const char *) fails to compile,
and although we have a cast embedded in VIR_FREE to work around poor
code that frees const char *, it's better to not rely on that hack.
* src/qemu/qemu_driver.c (qemuDiskPathToAlias): Change return type.
(qemuDomainBlockJobImpl): Update caller.
Given that we can now handle the target's disk shorthand, in addition
to an absolute path to the file or block device used on the host,
the term 'disk' fits a bit better as the parameter name than 'path'.
* include/libvirt/libvirt.h.in: Update some parameter names.
* src/libvirt.c (virDomainBlockStats, virDomainBlockStatsFlags)
(virDomainBlockPeek, virDomainGetBlockInfo, virDomainBlockJobAbort)
(virDomainGetBlockJobInfo, virDomainBlockJobSetSpeed)
(virDomainBlockPull): Likewise.
Commit 89b6284f made it possible to pass either a source name or
the target device to most API demanding a disk designation, but
forgot to update the documentation. It also failed to update
virDomainBlockStats to take both forms. This patch fixes both the
documentation and the remaining function.
Xen continues to use just device shorthand (that is, I did not
implement path lookup there, since xen does not track a domain_conf
to quickly tie a path back to the device shorthand).
* src/libvirt.c (virDomainBlockStats, virDomainBlockStatsFlags)
(virDomainGetBlockInfo, virDomainBlockPeek)
(virDomainBlockJobAbort, virDomainGetBlockJobInfo)
(virDomainBlockJobSetSpeed, virDomainBlockPull): Document
acceptable disk naming conventions.
* src/qemu/qemu_driver.c (qemuDomainBlockStats)
(qemuDomainBlockStatsFlags): Allow lookup by source name.
* src/test/test_driver.c (testDomainBlockStats): Likewise.
The WITH_VIRTUALPORT macro is defined to 0 when disabled, not
left undefined. So #if must be used instead of #ifdef
* src/util/virnetdevvportprofile.c: s/#ifdef/#if/
Up to now users have to give a full XML description on input when
device-detaching. If they omitted something it lead to unclear
error messages (like generated MAC wasn't found, etc.).
With this patch users can specify only those information which
specify one device sufficiently precise. Remaining information is
completed from domain.
In preparation of DHCP Snooping and the detection of multiple IP
addresses per interface:
The hash table that is used to collect the detected IP address of an
interface can so far only handle one IP address per interface. With
this patch we extend this to allow it to handle a list of IP addresses.
Above changes the returned variable type of virNWFilterGetIpAddrForIfname()
from char * to virNWFilterVarValuePtr; adapt all existing functions calling
this function.

When configuring a URI alias like this in 'libvirt.conf':
uri_aliases = [
"jj#j=qemu+ssh://root@127.0.0.1/system",
"sleet=qemu+ssh://root@sleet.cloud.example.com/system",
]
virsh -c jj#j
It will show this error message:
'no connection driver available for No connection for URI jj#j'
Actually，we expect this message below：
Malformed 'uri_aliases' config entry 'jj#j=qemu+ssh://root@127.0.0.1/system', aliases may only contain 'a-Z, 0-9, _, -'
Give this patch to fix this error.

This patch adds support for filtering of STP (spanning tree protocol) traffic
to the parser and makes us of the ebtables support for STP filtering. This code
now enables the filtering of traffic in chains with prefix 'stp'.
