87c972552c util: fix handling of unspecified port in URI
When no server name is provided in the URI, modern versions of libxml2
will set the port to '-1'. This is a change from behaviour with earlier
versions which set it to 0.

Libvirt expects the port to be 0 in these cases and as a result we get a
bug when connecting to URIs which lack a server name:

$ virsh  -c test+ssh:///default list
error: failed to connect to the hypervisor
error: Cannot recv data: Bad port '-1': Connection reset by peer

This libxml2 change was attempting to fix another bug identified by
libvirt where it didn't roundtrip URIs correctly in:

  beb7281055

Essentially libxml2 was not expecting apps to look at the URI port
field when the server name is not provided. This was a reasonable
assumption, but none the less libvirt did look at it :-)

The fix is to ensure we explicitly set port to 0 when server name
is not present, avoiding undefined behaviour for the port field in
libxml2.

66a85cb136 libvirt: add daemon itself as shutdown reason
This patch introduces a new shutdown reason "daemon" in order
to indicate that the daemon needed to force shutdown the domain
as the best course of action to take at the moment.

This action would occur during reconnection when processing

25dde37373 conf: Move VFIO AP validation from post parse to QEMU validation code
VFIO AP has a limitation on a single device per domain, however, when
commit 11708641 added the support for vfio-ap, check for this limitation
was performed as part of the post parse code. Generally, checks like that
should be performed within the driver's validation callback to eliminate
any slight chance of failing in post parse, which could potentially
result in the domain XML config vanishing.

f1e8d2f09a conf: Add new module node_device_util
There's a lot of stuff going on in src/conf/nodedev_conf which is
sometimes not directly related to config and we're not really consistent
with putting only parser/formatter related stuff here, e.g. like we do
for domains. So, let's start simply by adding a new module
node_device_util containing some of the helpers. Unfortunately, even
though these helpers tend to open a secondary driver connection and would
be much therefore better suited as a nodedev driver module, we can't do
that without pulling headers from the driver into conf/ and that's wrong
because we want conf/ to stay driver-agnostic.

68b2596f83 snapshot: Don't hose list on deletion failure
If qemuDomainSnapshotDiscard() fails for any reason (rare,
but possible with an ill-timed ENOMEM or if
qemuDomainSnapshotForEachQcow2() has problems talking to the
qemu guest monitor), then an attempt to retry the snapshot
deletion API will crash because we didn't undo the effects
of virDomainSnapshotDropParent() temporarily rearranging the
internal list structures, and the second attempt to drop
parents will dereference NULL.  Fix it by instead noting that
there are only two callers to qemuDomainSnapshotDiscard(),
and only one of the two callers wants the parent to be updated;
thus we can move the call to virDomainSnapshotDropParent()
into a code path that only gets executed on success.

e47949357b qemu: Don't ignore resume events
Since commit v4.7.0-302-ge6d77a75c4 processing RESUME event is mandatory
for updating domain state. But the event handler explicitly ignored this
event in some cases. Thus the state would be wrong after a fake reboot
or when a domain was rebooted after it crashed.

BTW, the code to ignore RESUME event after SHUTDOWN didn't make sense
even before making RESUME event mandatory. Most likely it was there as a
result of careless copy&paste from qemuProcessHandleStop.

The corresponding debug message was clarified since the original state
does not have to be "paused" only and while we have a "resumed" event,
the state is called "running".

8f0f8425d7 qemu: Narrow the shutdown reconnection failure reason window
The current qemuProcessReconnect logic paints a broad brush
determining that the shutdown reason must be crashed if it was
determined that the domain was started with -no-shutdown; however,
there's many other ways to get to the error label, so let's narrow
our reasoning window for using VIR_DOMAIN_SHUTOFF_CRASHED to the
period where we essentially know we've tried to create to the
monitor and before we were successful in opening the connection.

Failures that occur outside that window would thus be considered
as VIR_DOMAIN_SHUTOFF_UNKNOWN, at least for now.

296e05b54b qemu: Restore lost shutdown reason
When qemuProcessReconnectHelper was introduced (commit d38897a5d)
reconnection failure used VIR_DOMAIN_SHUTOFF_FAILED; however, that
was changed in commit bda2f17d to either VIR_DOMAIN_SHUTOFF_CRASHED
or VIR_DOMAIN_SHUTOFF_UNKNOWN.

When QEMU_CAPS_NO_SHUTDOWN checking was removed in commit fe35b1ad6
the conditional state was just left at VIR_DOMAIN_SHUTOFF_CRASHED.

So introduce qemuDomainIsUsingNoShutdown which will manage the
condition when the domain was started with -no-shutdown so that
when/if reconnection failure occurs we can restore the decision
point used to determine whether CRASHED or UNKNOWN is provided.

da4b0fd9d3 libxl: add support for soft reset

static void xen_hvm_crash_shutdown(struct pt_regs *regs)
{
        native_machine_crash_shutdown(regs);
        xen_reboot(SHUTDOWN_soft_reset);
}

but currently the libxl driver does not handle the soft reset
shutdown event. As a result, the guest domain never proceeds
past xen_reboot(), making it impossible for HVM domains to save
a crash dump using kexec.

This patch adds support for handling the soft reset event by
calling libxl_domain_soft_reset() and re-enabling domain death
events, which is similar to the xl tool handling of soft reset
shutdown event.

In order to provide some context, let's modify the existing

the failure. This should provide the context for writing the
polkit rules that would allow access via the driver.

67125e0d33 nwfilter: Instantiate active filter bindings during driver init
Commit 57f5621f modified nwfilterInstantiateFilter to detect when
a filter binding was already present before attempting to add the
new binding and instantiate it. Additionally, the change to
nwfilterStateInitialize to call virNWFilterBindingObjListLoadAllConfigs
(from commit c21679fa3f) to load active domain filter bindings, but
not instantiate them eventually leads to a problem for the QEMU
driver reconnection logic after a daemon restart where the filter
bindings would no longer be instantiated.

Subsequent commit f14c37ce4c replaced the nwfilterInstantiateFilter
with virDomainConfNWFilterInstantiate which uses @ignoreExists to
detect presence of the filter and still did not restore the filter
instantiation call when making the new nwfilter bindings logic active.

Thus in order to instantiate any active domain filter, we will call
virNWFilterBuildAll with 'false' to indicate the need to go through
all the active bindings calling virNWFilterInstantiateFilter to
instantiate the filter bindings.

29183778af nodedev: Document the udevEventHandleThread
Commit cdbe1332 neglected to document the API. So let's add some
details about the algorithm and why it was used to help future
readers understand the issues encountered.

NB: Management of the processing udev device notification is a
delicate balance between the udev process, the scheduler, and when
exactly the data from/for the socket is received. The balance is
particularly important for environments when multiple devices are
added into the system more or less simultaneously such as is done
for mdev or SRIOV. In these cases old libudev blocking on the udev
recv() occurs more frequently. It's expected that future devices
will follow similar algorithms. Even though the algorithm does
present some challenges for older OS's (such as Centos 6), trying
to rewrite the algorithm to fit both models would be more complex
and involve pulling the monitor object out of the private data
lockable object and would need to be guarded by a separate lock.
Devising such an algorithm to work around issues with older OS's
at the expense of more modern OS algorithms in newer event processing
code may result in unexpected issues, so the choice is to encourage
use of newer OS's with newer udev event processing code.

5a128712bc rpc: fix handling of SSH auth failure code
The result of libssh2_userauth_password is being assigned to 'ret' in
one branch and 'rc' in the other branch. Checks are all done against the
'ret' variable, so one branch never does the correct check.

disallows to define domains with more than one such hostdev device.
