Remove the iothreadspin array from cputune and replace with a cpumask
to be stored in the iothreadids list.
Adjust the test output because our printing goes in order of the iothreadids
list now.
Since it's only ever referenced in domain_conf.c, make the function
static, but also will need to move it to somewhere before it's referenced
rather than forward referencing it.
Add 'thread_id' to the virDomainIOThreadIDDef as a means to store the
'thread_id' as returned from the live qemu monitor data.
Remove the iothreadpids list from _qemuDomainObjPrivate and replace with
the new iothreadids 'thread_id' element.
Rather than use the default numbering scheme of 1..number of iothreads
defined for the domain, use the iothreadid's list for the iothread_id
Since iothreadids list keeps track of the iothread_id's, these are
now used in place of the many places where a for loop would "know"
that the ID was "+ 1" from the array element.
The new tests ensure usage of the <iothreadid> values for an exact number
of iothreads and the usage of a smaller number of <iothreadid> values than
iothreads that exist (and usage of the default numbering scheme).
Adding a new XML element 'iothreadids' in order to allow defining
specific IOThread ID's rather than relying on the algorithm to assign
IOThread ID's starting at 1 and incrementing to iothreads count.
This will allow future patches to be able to add new IOThreads by
a specific iothread_id and of course delete any exisiting IOThread.
Each iothreadids element will have 'n' <iothread> children elements
which will have attribute "id". The "id" will allow for definition
of any "valid" (eg > 0) iothread_id value.
On input, if any <iothreadids> <iothread>'s are provided, they will
be marked so that we only print out what we read in.
On input, if no <iothreadids> are provided, the PostParse code will
self generate a list of ID's starting at 1 and going to the number
of iothreads defined for the domain (just like the current algorithm
numbering scheme). A future patch will rework the existing algorithm
to make use of the iothreadids list.
On output, only print out the <iothreadids> if they were read in.
All the libraries use same parameters when building, why not have it in
one place at the begining of the Makefile.
This will also ensure no new mock library will have a problem with
missing e.g. MINGW_EXTRA_LDFLAGS.

In a lot places we use path like this:
$(srcdir)/../src/....
when in fact it can be:
$(top_srcdir)/src/

The lookup is just for check whether a domain we are about to add does
not already exists. Well, the virDomainObjListAdd() function does that
for us already so there's no need to duplicate the check.

the element 'family' would not be freed.

If a user hot-attaches the guest agent channel libvirt would ignore it
until the restart of libvirtd or shutdown/destroy and start of the VM
itself.
This patch adds code that opens or closes the guest agent connection
according to the state of the guest agent channel according to
connect/disconnect events.
To allow opening the channel from the event handler qemuConnectAgent
needed to be exported.
When the guest agent channel gets hotplugged to a VM, libvirt would
still report that "QEMU guest agent is not configured" rather than
stating that the connection was not established yet.
Currently the code won't be able to connect to the agent after hotplug
but that will change in a later patch.
As the qemuFindAgentConfig() helper is quite helpful in this case move
it to a more usable place and export it.
Rearrange code so that the local variable is always initialized and
disposed.

Since net->model is not defined for containers we shouldn't touch it.
In case network adapter model is defined, a warning about ignoring
it is shown.

Fix for such a case:
1. Domain A and B xml contain the same SRIOV net hostdev(<interface
type='hostdev' /> with same pci address).
2. virsh start A (Successfully, and configure the SRIOV net with
custom mac)
3. virsh start B (Fail because of the hostdev used by domain A or other
reason.)
In step 3, 'virHostdevNetConfigRestore' is called for the hostdev
which is still used by domain A. It makes the mac/vlan of the SRIOV net
change.
Code Change in this fix:
1. As the pci used by other domain have been removed from
'pcidevs' in previous loop, we only restore the nic config for
the hostdev still in 'pcidevs'(used by this domain)
2. update the comments to make it more clear

- Make sure aarch64 host-passthrough works correctly
- Make sure libvirt doesn't choke on cpu model=host, which is what
virt-install/virt-manager were incorrectly specifying up until recently.
virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.

ListFindByID() still requires to step through items in the hash table
(in the worst case scenario through all of them), lock each one and
compare whether we've found what we're looking for. This is suboptimal
as locking a domain object means we need to wait for the current API
running over the object to finish.
Unfortunately, we can't drop the function completely because we have
this public API virDomainLookupByID which we can't drop.

This hash table will contain the same data as already existing one.
The only difference is that while the first table uses domain uuid as
key, the new table uses domain name. This will allow much faster (and
lockless) lookups by domain name.

Every domain that grabs a domain object to work over should
reference it to make sure it won't disappear meanwhile.

This is basically turning qemuDomObjEndAPI into a more general
function. Other drivers which gets a reference to domain objects may
benefit from this function too.

Since we haven't implemented balloon parameters tuning
