Libxml2 has awful error reporting behaviour when reading files. When
we fail to load a file from the test driver we see:
$ virsh -c test:///wibble.xml
I/O warning : failed to load external entity "/wibble.xml"
error: failed to connect to the hypervisor
error: XML error: failed to parse xml document '/wibble.xml'
where the I/O warning line is something printed by libxml2 itself,
which also lacks any useful detail.
Switching to our own file reading code we can massively improve
things:
$ ./build/tools/virsh -c test:///wibble.xml
error: failed to connect to the hypervisor
error: Failed to open file '/wibble.xml': No such file or directory
Using 10 MB as an upper limit on XML file size ought to be sufficient
for any XML files libvirt is reading.

The libxml2 error handling gets the filename from a libxml2 struct, but
it is better to not assume libxml2 knows the filename being parsed, as

The virNetDaemon code now only concerns itself with preventing auto
shutdown of the local daemon. Logind is now handled by the new
virInhibitor object, for QEMU, LXC and LibXL. This fixes two notable
bugs
* Running virtual networks would prevent system shutdown
* Loaded ephemeral secrets would prevent system shutdown

This initial conversion of the drivers switches them over to use
the virInhibitor APIs in local daemon only mode. Communication to
logind is still handled by the virNetDaemon class logic.
This mostly just replaces upto 3 fields in the driver state
with a single new virInhibitor object, but otherwise should not
change functionality besides replacing atomics with mutex protected
APIs.
The exception is the LXC driver which has been trying to inhibit
shutdown shutdown but silently failing to, since nothing ever
remembered to set the 'inhibitCallback' pointer in the driver
state struct.

The system inhibitor locks are currently handled by code in the
virNetDaemon class. The driver code invokes a callback provided
by the daemon when it wants to start or end inhibition.
When the first inhibition is started, the daemon will call out
to logind to apply it system wide.
This has many flaws
* A single message is registered with logind regardless of
what driver holds the inhibition
* An inhibition of daemon shutdown can't be acquired
without also inhibiting system shutdown
* Config of the inhibitions cannot be tailored by the
driver
The new virInhibitor object addresses these:
* The object directly manages an inhibition with logind
privately to the driver, enabling custom messages to
be set.
* It is possible to acquire an inhibition locally to the
daemon without forwarding it to logind.

The exit-on-error=false argument of migrate-incoming tells the QEMU
process to keep running when incoming migration fails, which helps us in
two ways:
1. When migration enters Finish phase to cleanup the process, the domain
might not even exist on the destination (because it has already been
cleaned up by EOF monitor callback) and we would get rather unhelpful
"operation failed: domain is no longer running" error message.
2. We can get the error that caused incoming migration to fail directly
from QEMU via query-migrate QMP command.

The function is only used during incoming migration in the beginning of
Finish phase to detect if QEMU already died but EOF handler haven't had
a chance to do its job yet. It calls query-status QMP command, but
ignores the result. By calling query-migrate instead we can achieve the
same functionality if QEMU is dead and even get meaningful error from
"error-desc" in case the incoming migration failed and QEMU is still
running.

In my previous commit v10.10.0-48-g2d222ecf6e I've made us enable
I/O APIC when there is an IOMMU with EIM. This works well. What
does not work is case when there's just an IOMMU without EIM but
with 256+ vCPUS. Problem is that post parsing happens in two
stages: general domain post parse (where
qemuDomainDefEnableDefaultFeatures() is called) and then per
device post parse (where qemuDomainIOMMUDefPostParse() is
called). Now, in aforementioned case it is the device post parse
phase where EIM is enabled but the code that would enable
VIR_DOMAIN_FEATURE_IOAPIC has already run.
To resolve this, make the domain post parse callback "foresee"
the future enabling of EIM so that it can turn on I/O APIC
beforehand.

Add a new a attribute, deprecated_features='on|off' to the <cpu>

CPU model on or off. When this attribute is paired with 'on',
deprecated features will not be filtered. When paired with 'off', any
CPU features that are flagged as deprecated will be listed under the
CPU model with the 'disable' policy.
Example:
<cpu mode='host-model' check='partial' deprecated_features='off'/>
The absence of this attribute is equivalent to the 'on' option.
The deprecated features that will populate the domain XML are the same
features that result in the virsh domcapabilities command with the
--disable-deprecated-features argument present.
It is recommended to define a domain XML with this attribute set to
'off' to ensure migration to machines that may outright drop these
features in the future.

For the full history behind this patch, look at the following:
https://issues.redhat.com/browse/RHEL-7036
commit v10.7.0-101-ga37bd2a15b
commit v10.8.0-rc2-8-gbcd5ae4e73
Summary: original problem was unexpected failure of update-device when
the user hadn't changed anything other than online status of the guest
NIC (which should always be allowed).
The first commit "fixed" this by avoiding the allocation of a new
ActualNetDef (i.e. creating a new networkport) for *all* network
device updates (because that was inappropriately changing which
ethernet physdev should be used for a macvtap connection, which by
design can't be handled in an update-device).
But this commit caused a regression for update-device of bridge-based
network devices (because some the updates of certain attributes *do*
require the ActualNetDef be re-allocated), so...
The 2nd commit narrowed the list of network types that get the "don't
allocate new ActualNetDef" treatment (so that only interfaces
connected to a network that uses a pool of ethernet VFs *being used in
passthrough mode* qualify).
But then it was pointed out that this re-broke simple updates of
devices that used a direct/macvtap network in "bridge" mode (because
it's possible to list multiple physdevs to use for bridge mode, in
which case the network driver attempts to "load balance" (and so a new
allocation might have a different ethernet physdev which, again, can't
be supported in a device-update).
So this (single line of code) patch *widens* the list of network types
that don't allocate a new ActualNetDef to also include the other
direct (macvtap) modes, e.g. bridge, private, etc.
