If no network configuration is provided, LXC only provides the loopback
interface. To match this, we need to use the privnet feature. LXC will
also define a 'none' network type in its 1.0.0 version that fits
libvirt LXC driver's default.

Tmpfs relative size and default 50% size values aren't supported as
we have no idea of the available memory at the conversion time.

LXC rootfs can be either a directory or a block device or an image
file. The first two types have been implemented, but the image file is
still to be done since LXC auto-guesses the file format at mount time
and the LXC driver doesn't support the 'auto' format.

This function aims at converting LXC configuration into a libvirt
domain XML description to help users migrate from LXC to libvirt.

Here is an example of how the lxc configuration works:
virsh -c lxc:/// domxml-from-native lxc-tools /var/lib/lxc/migrate_test/config

It is possible that some parts couldn't be properly mapped into a
domain XML fragment, so users should carefully review the result
before creating the domain.

fstab files in lxc.mount lines will need to be merged into the
configuration file as lxc.mount.entry.

As we can't know the amount of memory of the host, we have to set a
default value for max_balloon that users will probably want to adjust.

Add a new backend for any character device.  This backend uses channel
in spice connection.  This channel is similar to spicevmc, but
all-purpose in contrast to spicevmc.

Apart from spicevmc, spiceport-backed chardev will not be formatted
into the command-line if there is no spice to use (with test for that
as well).  For this I moved the def->graphics counting to the start
of the function so its results can be used in rest of the code even in
the future.

Add a new <timer> for the HyperV reference time counter enlightenment
and the iTSC reference page for Windows guests.

This feature provides a paravirtual approach to track timer events for
the guest (similar to kvmclock) with the option to use real hardware
clock on systems with a iTSC with compensation across various hosts.

According to the documentation describing various tunables for domain
timers not all the fields are supported by all the driver types. Express
these in the RNG:

- rtc, platform: Only these support the "track" attribute.
- tsc: only one to support "frequency" and "mode" attributes
- hpet, pit: tickpolicy/catchup attribute/element
- kvmclock: no extra attributes are supported

Additionally the attributes of the <catchup> element for
tickpolicy='catchup' are optional according to the parsing code. Express
this in the XML and fix a spurious space added while formatting the
<catchup> element and add tests for it.

With my recent work on the test, both time() and localtime() are used.
While mocking the former one, we get predictable result for UTC. But
since the latter function uses timezone to get local time, the result of
localtime() is not so predictive. Therefore, we must set the TZ variable
at the beginning of the test. To be able to catch some things that work
just by a blind chance, I'm choosing a virtual timezone that (hopefully)
no libvirt developer resides in.

The qemuxml2argvtest is run on more platforms than linux. For instance
FreeBSD. On these platforms we are, however, not mocking time() which
results in current time being fetched from system and hence tests number
32 and 33 failing.

When trying to introduce a test for previous patch, I've
noticed that the command line is constructed using current
time. This won't work in our test suite (unless you guys
wants to set a specific time prior to each test run :) ).
Therefore we need to mock calls to time(2) to return the
same value every time it's called.

Adding tests for new virKMod{Config|Load|Unload}() API's.

A test for virKModIsBlacklisted() would require some setup which cannot
be assumed.

The previous patch fixed "forwardPlainNames" so that it really is
doing only what is intended, but left the default to be
"forwardPlainNames='no'". Discussion around the initial version of
that patch led to the decision that the default should instead be
"forwardPlainNames='yes'" (i.e. the original behavior before commit
f3886825). This patch makes that change to the default.

In commit f3868259 we began adding the options

  --domain-needed
  --local=/$mydomain/

to all dnsmasq commandlines with the stated reason of preventing
forwarding of DNS queries for names that weren't fully qualified
domain names ("FQDN", i.e. a name that included some "."s and a domain
name). This was later changed to

  domain-needed
  local=/$mydomain/

when we moved the options from the dnsmasq commandline to a conf file.

The original patch on the list, and discussion about it, is here:

  https://www.redhat.com/archives/libvir-list/2012-August/msg01594.html

When a domain name isn't specified (mydomain == ""), the addition of
"domain-needed local=//" will prevent forwarding of domain-less
requests to the virtualization host's DNS resolver, but if a domain
*is* specified, the addition of "local=/domain/" will prevent
forwarding of any requests for *qualified* names within that domain
that aren't resolvable by libvirt's dnsmasq itself.

An example of the problems this causes - let's say a network is
defined with:

   <domain name='example.com'/>
   <dhcp>
      ..
      <host mac='52:54:00:11:22:33' ip='1.2.3.4' name='myguest'/>
   </dhcp>

This results in "local=/example.com/" being added to the dnsmasq options.

If a guest requests "myguest" or "myguest.example.com", that will be
resolved by dnsmasq. If the guest asks for "www.example.com", dnsmasq
will not know the answer, but instead of forwarding it to the host, it
will return NOT FOUND to the guest. In most cases that isn't the
behavior an admin is looking for.

A later patch (commit 4f595ba6) attempted to remedy this by adding a
"forwardPlainNames" attribute to the <dns> element. The idea was that
if forwardPlainNames='yes' (default is 'no'), we would allow
unresolved names to be forwarded. However, that patch was botched, in
that it only removed the "domain-needed" option when
forwardPlainNames='yes', and left the "local=/mydomain/".

Really we should have been just including the option "--domain-needed
--local=//" (note the lack of domain name) regardless of the
configured domain of the network, so that requests for names without a
domain would be treated as "local to dnsmasq" and not forwarded, but
all others (including those in the network's configured domain) would
be forwarded. We also shouldn't include *either* of those options if
forwardPlainNames='yes'. This patch makes those corrections.

This patch doesn't remedy the fact that default behavior was changed
by the addition of this feature. That will be handled in a subsequent
patch.

I've received a notice over IRC that on some systems, the
virnetdevbandwidthtest is not linked with libxml:

  /usr/bin/ld: virnetdevbandwidthtest.o: undefined reference to symbol 'xmlStrEqual@@LIBXML2_2.4.30'
  /usr/lib/x86_64-linux-gnu/libxml2.so.2: error adding symbols: DSO missing from command line

Trivial way avoiding this is to add LIBXML_LIBS to
virnetdevbandwidthtest_LDADD.

And while doing this, fix one error raised by coverity. With
current code, @actual_cmd is allowed to be NULL for the whole
run of testVirNetDevBandwidthSet. However, if something else
was expected, the @actal_cmd is passed to virtTestDifference
which dereference it immediately.

This reverts commit 2996e6be
and some parts of 2636dc8c.

The former one tried to implement QoS setting on bridgeless networks.
However, as discussed upstream [1], the patch is far away from being
useful in even a single case. The whole idea of network QoS is to have
aggregated limits over several interfaces. This patch is doing
completely the opposite when merging two QoS settings (from the network
and the domain interface) into one which is then set at the domain
interface itself, not the network.

The latter one is the test for the previous one. Now none of them makes
sense.

When all source CPU XMLs contain just a single CPU model (with a
possibly varying set of additional feature elements),
virConnectBaselineCPU will try to use this CPU model in the computed
guest CPU. Thus, when used on just a single CPU (useful with
VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES), the result will not use a
different CPU model.

If the computed CPU uses the source model, set fallback mode to 'forbid'
to make sure the guest CPU will always be as close as possible to the
source CPUs.

linuxNodeInfoCPUPopulate is only used in the nodeinfo.c file

Windows doesn't allow : in filenames.

Commit 21685c95 added files with a : in

Replace : with - in the offending filenames and adapt the test case.

Libvirtd would crash if a domain contained an empty cdrom drive of
