326e5941cd qemu: Generate channel target paths on hotplug as well
Since commit 7140807917, qemu agent
channel cannot be plugged in because we won't generate its path
automatically.  Let's not only fix that, but also add tests for it so
next time it's checked for.

f371704708 qemuhotplugtest: Test live data
Until now, the only hot thing in this test was the name.  That's because
we set the id to '-1' before every test.  With this change, we test the
hotplug on live domains as the name suggests and as it should be.

919d0b368e Revert "qemu_hotplug: fix checking graphics ports"
This reverts commit 1ccc7fbff3.

We cannot check ports if autoport is set because we set ports to 0 while
parsing device XML.

1ccc7fbff3 qemu_hotplug: fix checking graphics ports
We cannot change ports for running domain and we should error out if
autoport is enabled.

119cd06ef7 domain_conf: always set primary video device as primary
We always place primary video device at first place, to make it easier
to create a qemu command or format an xml, but we should also set the
primary boolean for primary video device to 'true'.

36785c7e77 device: cleanup input device code
The current code was a little bit odd.  At first we've removed all
possible implicit input devices from domain definition to add them later
back if there was any graphics device defined while parsing XML
description.  That's not all, while formating domain definition to XML
description we at first ignore any input devices with bus different to
USB and VIRTIO and few lines later we add implicit input devices to XML.

This seems to me as a lot of code for nothing.  This patch may look
to be more complicated than original approach, but this is a preferred
way to modify/add driver specific stuff only in those drivers and not
deal with them in common parsing/formating functions.

The update is to add those implicit input devices into config XML to
follow the real HW configuration visible by guest OS.

There was also inconsistence between our behavior and QEMU's in the way,
that in QEMU there is no way how to disable those implicit input devices
for x86 architecture and they are available always, even without graphics
device.  This applies also to XEN hypervisor.  VZ driver already does its
part by putting correct implicit devices into live XML.

81ba2298b2 video: cleanup usage of vram attribute and update documentation
The vram attribute was introduced to set the video memory but it is
usable only for few hypervisors excluding QEMU/KVM and the old XEN
driver. Only in case of QEMU the vram was used for QXL.

This patch updates the documentation to reflect current code in libvirt
and also changes the cases when we will set the default vram attribute.
It also fixes existing strange default value for VGA devices 9MB to 16MB
because the video ram should be rounded to power of two.

The change of default value could affect migrations but I found out that
QEMU always round the video ram to power of two internally so it's safe
to change the default value to the next closest power of two and also
silently correct every domain XML definition. And it's also safe because
we don't pass the value to QEMU.

36cc189a46 tests: Add test cases for previous commit
This commit is rather big. Firstly, the in memory config
representation is adjusted like if security_driver was set to "none".
The rest is then just adaptation to the new code that will generate
different seclabels.

While running qemuhotplugtest, it was found that valgrind pointed out
the following memory leak:

...and 10 more.

Problem is, since 20745748 we do both, parse <alias/> elements from
XML files and call qemuAssignDeviceAliases(). While generating runtime
info for domain at runtime is just fine in the test, we can parse just
inactive XML and remove all <alias/>-es from the XML files.

65487c0fc5 conf: re-situate <bandwidth> element in <interface>
This moves the call to virNetDevBandwidthFormat() in
virDomainNetDefFormat() to be called right after the call to
virNetDevVPortProfileFormat(), so that a single chunk of that function
can be placed inside an if that conditionally calls
virDomainActualNetDefContentsFormat() instead (next patch). The
re-ordering necessitates modifying a couple of test data files.

bc18373391 conf: Add keyboard input device type
There is no keyboard support currently in libvirt.

For some platforms (PPC64 QEMU) this makes graphics unusable,
since the keyboard is not implicit and it can't be added via libvirt.

9e45b3dfe3 qemuhotplugtest: Introduce test for chardev hotplug
The test is currently testing just device update function. However,
chardev hotplug is implemented just for device attach and detach. This
fact means, the test needs to be rewritten (the majority of the code is
still shared). Moreover, we are now able to pass VM among multiple test
runs. So for instance, while we add a device in the first run, we can
remove it in the second run.

As my punishment for the break in 7f15ebc7 (fixed in 752596b5dd) I'm
introducing this test to make sure it won't happen again. Currently,
only test for <graphics/> is supported.
