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

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.

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.

qemuProcessStart created two references to virQEMUDriverConfigPtr before
calling fork():
cfg = virQEMUDriverGetConfig(driver);
...
hookData.cfg = virObjectRef(cfg);
However, the child only unreferenced hookData.cfg and the parent only
removed the cfg reference. That said, we don't need to increment the
reference counter when assigning cfg to hookData. Both the child and the
parent will correctly remove the reference on cfg (the child will do
that through hookData).

Since commit 297c99a5 an invalid source definition XML of a character
device that is used as backend for RNG devices, smartcards and redirdevs
causes crash of the daemon when parsing such a definition.
The device types mentioned above are not a part of a regular character
device but are backends for other types. Thus when parsing such device
NULL is passed as the argument @chr_def. Later when checking the
validity of the definition @chr_def was dereferenced when parsing a UNIX
socket backend with missing path of the socket and crashed the daemon.
Sample offending configuration:
<devices>
...
<rng model='virtio'>
<backend model='egd' type='unix'>
<source mode='bind' service='1024'/>
</backend>
</rng>
</devices>

When passing in custom driver XML, allow a block like
<domain xmlns:test='http://libvirt.org/schemas/domain/test/1.0'>
...
<test:runstate>5</test:runstate>
</domain>
This is only read at initial driver start time, and sets the initial
run state of the object. This is handy for UI testing.
It's only wired up for domains, since that's the only conf/
infrastructure that supports namespaces at the moment.
