958e0431a9 tests: Add test for properly removing cachetune entries
Cachetune for unavailable vCPUs should be cleared the same way vcpupin and other
things do, so let's add tests for it.

21bfd1e9b9 conf: error out for multiple source elements while parsing chardev
Currently we accept and correctly parse this chardev XML:

  ...
  <channel type='tcp'>
    <source mode='connect'/>
    <source mode='bind' host='localhost'/>
    <source service='4567'/>
    <target type='virtio' name='test'/>
  </channel>
  ...

The parsed formatted XML is:

  ...
  <channel type='tcp'>
    <source mode='connect' host='localhost' service='4567'/>
    <target type='virtio' name='test'/>
  </channel>
  ...

That behavior is super wrong and should not be allowed.  If you notice
the current parse takes the first found attribute and uses that value,
so for example from the "<source mode='bind' host='localhost'/>" only
the "host" attribute is used.  It works the same way for all possible
attributes that we are able to parse for source element.

This patch enforces providing only one source element for all character
devices, only for UDP type we allow to provide two source elements
since you can specify both modes.

e6e26a899d tests: unify qemu binary paths for all qemu related tests
Our test data used a lot of different qemu binary paths and some
of them were based on downstream systems.

Note that there is one file where I had to add "accel=kvm" because
the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm".

f19390d2d3 domain_conf: vnc: preserve autoport value if no port was specified
The issue is that if this graphics definition is provided:

  <graphics type='vnc' port='0'/>

it's parsed as:

  <graphics type='vnc' autoport='no'>
    <listen type='address'/>
  </graphics>

but if the resulting XML is parsed again the output is:

  <graphics type='vnc' port='-1' autoport='yes'>
    <listen type='address'/>
  </graphics>

and this should not happen.  The XML have to always remain the same
after it was already parsed by libvirt.

5847bc5c64 conf: Add XML for individual vCPU hotplug
Individual vCPU hotplug requires us to track the state of any vCPU. To
allow this add the following XML:

<domain>
  ...
  <vcpu current='2'>3</vcpu>
  <vcpus>
    <vcpu id='0' enabled='yes' hotpluggable='no' order='1'/>
    <vcpu id='1' enabled='yes' hotpluggable='yes' order='2'/>
    <vcpu id='1' enabled='no' hotpluggable='yes'/>
  </vcpus>
  ...

The 'enabled' attribute allows to control the state of the vcpu.
'hotpluggable' controls whether given vcpu can be hotplugged and 'order'
allows to specify the order to add the vcpus.

acc83afe33 vnc: add support for listen type 'socket'
VNC graphics already supports sockets but only via 'socket' attribute.
This patch coverts that attribute into listen type 'socket'.

For backward compatibility we need to handle listen type 'socket' and 'socket'
attribute properly to support old XMLs and new XMLs.  If both are provided they
have to match, if only one of them is provided we need to be able to parse that
configuration too.

To not break migration back to old libvirt if the socket is provided by user we
need to generate migratable XML without the listen element and use only 'socket'
attribute.

b1fc6a7b73 conf: domain: reject name containing '/'
Trying to define a domain name containing an embedded '/'
will immediately fail when trying to write the XML to disk for
our stateful drivers. This patch explicitly rejects names
containing a '/', and provides an xmlopt feature for drivers
to avoid this validation check, which is enabled in every
non-stateful driver that already has xmlopt handling wired up.

(Technically this could reject a previously accepted vmname like
 '/foo', however at least for the qemu driver that falls over
 later when starting qemu)

  We implicitly test it elsewhere but I figure it's better to be explicit,

  back compat if/when we support <listen type='socket'/> syntax
