When querying for kvm, we try to find 'enabled' field. Hence the error
message should report we haven't found 'enabled' and not 'running'
(which is not even in the reply). Probably a typo or copy-paste error.
The qemuDomainChangeNet() is called when 'virsh update-device' is
invoked on a NIC. Currently, we fail to update the QoS even though
we have routines for that.

So far the virNetDevBandwidthEqual() expected both ->in and ->out items
to be allocated for both @a and @b compared. This is not necessary true
for all our code. For instance, running 'update-device' twice over a NIC
with the very same XML results in SIGSEGV-ing in this function.

libvirt previously recognized NFS, GFS2, OCFS2, and AFS filesystems as
"shared", and thus eligible for exceptions to certain rules/actions
about chowning image files before handing them off to a guest. This
patch widens the definition of "shared filesystem" to include SMB and
CIFS filesystems (aka "Windows file sharing"); both of these use the
same protocol, but different drivers so there are different magic
numbers for each.
This test is there to ensure that our capabilities detection code isn't
broken somehow.
How to gather test data:
Firstly, the data is split into two separate files. The former (with
suffix .replies) contains all the qemu replies. This is very fragile as
introducing a new device can mean yet another monitor command and hence
edit of this file in the future. But there's no better way of doing
this. To get this data simply turn on debug logs and copy all the
QEMU_MONITOR_IO_PROCESS lines. But be careful to not copy incomplete
ones (yeah, we report some incomplete lines too). Long story short, at
the libvirtd startup, a dummy qemu is spawn to get all the capabilities.
The latter (with suffix .caps) contains capabilities XML. Just start a
domain and copy the corresponding part from its state XML file.
Including <qemuCaps> tag.

In a few cases we might want to not care if monitor command executed on
the mocked monitor matches the one we have reply for. Sounds crazy, but
if we just want monitor to return certain values (e.g. read from a file)
there is no need to care about command match.

Currently, when creating a new mocked monitor, the greeting can't be
chosen. This is crucial for next patches, because some info as qemu

The libvirtd server pushes data out to clients. It does not
know what protocol version the client might have, so must be
conservative and use the old payload limits. ie send no more
than 256kb of data per packet.

The problem is described by [0] but its effect on libvirt is that
starting a container with a full distro running systemd after having
stopped it simply fails.
The container cleanup now calls the machined Terminate function to make
sure that everything is in order for the next run.

The memory size in virNodeGetInfo python API binding is reported in MiB
instead of KiB (like we have in C struct). However, there already might
be applications out there relying on this inconsistence so we can't
simply fix it. Document this sad fact as known bug.
Currently the VMware version check code only supports two types of
VMware backends, Workstation and Player. But in the near future we will
have an additional one so we need to support more. Additionally, we
discover and cache the path to the vmrun binary so we should use that
path when using the corresponding binary from the VMware VIX SDK.

When running 'make dist' on a system without policykit, we currently

On some systems (linux, cygwin and gnukfreebsd) rpcgen generates files
which when compiling produces this warning:
remote/remote_protocol.c: In function 'xdr_remote_node_get_cpu_stats_ret':
remote/remote_protocol.c:530: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
Hence, on those systems we need to post-process the files by the
rpc/genprotocol.pl perl script. At the beginning of the script the OS is
detected via $^O perl variable. From my latest build on FreeBSD I see we
need to fix the code there too. On FreeBSD the variable contains
'freebsd' string:

The debug message said there was a timeout of 0 pending for -1 ms which
made me think this is where a hang was coming from but according to the
function comments this case means that there is no timeout pending so
make the debug message say that instead of saying there's a -1 ms
timeout.
While BSDs don't support process creation timestamp information via
PEERCRED for Unix sockets, we need to actually initialize the value
because it is used by the libvirt code.
When a client disconnects from libvirtd, all event callbacks
must be removed. This involves running the public API
virConnectDomainEventDeregisterAny
This code does not run in normal API dispatch context, so no
identity was set. The result was that the access control drivers
denied the attempt to deregister callbacks. The callbacks thus
continued to trigger after the client was free'd causing fairly
predictable use of free memory & a crash.
This can be triggered by any client with readonly access when
the ACL drivers are active.

It's possible to create a domain which will only use a TLS port
and will not have a non-TLS port set by using:
<graphics type='spice' autoport='yes' defaultMode='secure'/>
In such a setup, the 'graphics' node for the running domain will be:
<graphics type='spice' tlsPort='5900'
autoport='yes' listen='127.0.0.1'
defaultMode='secure'>
However, cmdDomDisplay loops over all the 'graphics' node, and it
ignores nodes which don't have a 'port' attribute. This means
'virsh domdisplay' will only return an empty string for domains
as the one above.
This commit looks for both 'port' and 'tlsPort' before deciding
to ignore a graphics node. It also makes sure 'port' is not printed
when it's not set.
This makes 'virsh domdisplay' return
'spice://127.0.0.1?tls-port=5900' for domains using only a TLS
port.
