5f1837eaca Pass config file object through to driver open methods
The virConnectOpenInternal method opens the libvirt client
config file and uses it to resolve things like URI aliases.

There may be driver specific things that are useful to
store in the config file too, so rather than have them
re-parse the same file, pass the virConfPtr down to the
drivers.

c36b1f7b6a Change virDevicePCIAddress to virPCIDeviceAddress
We had both and the only difference was that the latter also included
information about multifunction setting.  The problem with that was that
we couldn't use functions made for only one of the structs (e.g.
parsing).  To consolidate those two structs, use the one in virpci.h,
include that in domain_conf.h and add the multifunction member in it.

185d13b1b0 conf: refactor checking for unsupported memory devices
Introduce a helper to check supported device and domain config and move
the memory hotplug checks to it.

The advantage of this approach is that by default all new features are
considered unsupported by all hypervisors unless specifically changed
rather than the previous approach where every hypervisor would need to
declare that a given feature is unsupported.

cc48d3a122 util: Add a return value to void hash iterators
Our existing virHashForEach method iterates through all items disregarding the
fact, that some of the iterators might have actually failed. Errors are usually
dispatched through an error element in opaque data which then causes the
original caller of virHashForEach to return -1. In that case, virHashForEach
could return as soon as one of the iterators fail. This patch changes the
iterator return type and adjusts all of its instances accordingly, so the
actual refactor of virHashForEach method can be dealt with later.

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.

internally for stub driver validation.

Advantages:

  * possible values are well-defined
  * typos in driver names will be detected at compile time
  * avoids having several copies of the same string around
  * no error checking required when setting / getting value

The names used mirror those in the
virDomainHostdevSubsysPCIBackendType enumeration.

427067f7ed xen: fix race in refresh of config cache
The xenXMConfigCacheRefresh method scans /etc/xen and loads
all config files it finds. It then scans its internal hash
table and purges any (previously) loaded config files whose
refresh timestamp does not match the timestamp recorded at
the start of xenXMConfigCacheRefresh(). There is unfortunately
a subtle flaw in this, because if loading the config files
takes longer than 1 second, some of the config files will
have a refresh timestamp that is 1 or more seconds different
(newer) than is checked for. So we immediately purge a bunch
of valid config files we just loaded.

To avoid this flaw, we must pass the timestamp we record at
the start of xenXMConfigCacheRefresh() into the
xenXMConfigCacheAddFile() method, instead of letting the
latter call time(NULL) again.

It is not. The defition created that is converted from the internal xend

ffc40b63b5 conf: make virNodeDevCapData an official type
For some reason a union (_virNodeDevCapData) that had only been
declared inside the toplevel struct virNodeDevCapsDef was being used
as an argument to functions all over the place. Since it was only a
union, the "type" attribute wasn't necessarily sent with it. While
this works, it just seems wrong.

This patch creates a toplevel typedef for virNodeDevCapData and
virNodeDevCapDataPtr, making it a struct that has the type attribute
as a member, along with an anonymous union of everything that used to
be in union _virNodeDevCapData. This way we only have to change the
following:

  s/union _virNodeDevCapData */virNodeDevCapDataPtr /

and

  s/caps->type/caps->data.type/

This will make me feel less guilty when adding functions that need a
pointer to one of these.

This patch adds code that parses and formats configuration for memory

A complete configuration of a memory device:
<memory model='dimm'>

    <pagesize unit='KiB'>4096</pagesize>
    <nodemask>1-3</nodemask>
  </source>
  <target>
    <size unit='KiB'>524287</size>
    <node>1</node>
  </target>
</memory>
