The code supported unit='E' for "exabyte", but the RNG did not;
conversely, the RNG supported "z" and "y" but the code did not
(I'm jealous if you have that much storage, particularly since
it won't fit in 64-bit off_t).  Also, the code supported
<allocation unit='...'>, but not the RNG.

In an effort to make 'unit' more worthwhile in future patches,
it's easier to share it between files.

In making this factorization, note that absFilePath is more
permissive than 'path', so storage pools and storage volumes
will now validate with a wider set of file names than before.
I don't think this should be a problem in practice.

This is the new interface type that sets up an SR-IOV PCI network
device to be assigned to the guest with PCI passthrough after
initializing some network device-specific things from the config
(e.g. MAC address, virtualport profile parameters). Here is an example
of the syntax:

  <interface type='hostdev' managed='yes'>
    <source>
      <address type='pci' domain='0' bus='0' slot='4' function='3'/>
    </source>
    <mac address='00:11:22:33:44:55'/>
    <address type='pci' domain='0' bus='0' slot='7' function='0'/>
  </interface>

This would assign the PCI card from bus 0 slot 4 function 3 on the
host, to bus 0 slot 7 function 0 on the guest, but would first set the
MAC address of the card to 00:11:22:33:44:55.

NB: The parser and formatter don't care if the PCI card being
specified is a standard single function network adapter, or a virtual
function (VF) of an SR-IOV capable network adapter, but the upcoming
code that implements the back end of this config will work *only* with
SR-IOV VFs. This is because modifying the mac address of a standard
network adapter prior to assigning it to a guest is pointless - part
of the device reset that occurs during that process will reset the MAC
address to the value programmed into the card's firmware.

Although it's not supported by any of libvirt's hypervisor drivers,
usb network hostdevs are also supported in the parser and formatter
for completeness and consistency. <source> syntax is identical to that
for plain <hostdev> devices, except that the <address> element should
have "type='usb'" added if bus/device are specified:

  <interface type='hostdev'>
    <source>
      <address type='usb' bus='0' device='4'/>
    </source>
    <mac address='00:11:22:33:44:55'/>
  </interface>

If the vendor/product form of usb specification is used, type='usb'
is implied:

  <interface type='hostdev'>
    <source>
      <vendor id='0x0012'/>
      <product id='0x24dd'/>
    </source>
    <mac address='00:11:22:33:44:55'/>
  </interface>

Again, the upcoming patch to fill in the backend of this functionality
will log an error and fail with "Unsupported Config" if you actually
try to assign a USB network adapter to a guest using <interface
type='hostdev'> - just use a standard <hostdev> entry in that case
(and also for single-port PCI adapters).

Language bindings may well want to use the libvirt-api.xml and
libvirt-qemu-api.xml files to either auto-generate themselves,
or sanity check the manually written bindings for completeness.
Currently these XML files are not installed as standard, merely
ending up as a %doc file in the RPM.

This changes them to be installed into $prefix/share/libvirt/apis/
The *-refs.xml files are not installed, since those are only

Someone mentioned to me that they interpreted this section of the KVM

creating a qemu commandline and converting it to XML with
domxml-from-native.  I don't think that's the intent of
domxml-from-native, so I added that clarification.

Commit b170eb99 introduced a bug: domains that had an explicit
<seclabel type='none'/> when started would not be reparsed if
libvirtd restarted.  It turns out that our testsuite was not
exercising this because it never tried anything but inactive
parsing.  Additionally, the live XML for such a domain failed
to re-validate.  Applying just the tests/ portion of this patch

Curently security labels can be of type 'dynamic' or 'static'.
If no security label is given, then 'dynamic' is assumed. The
current code takes advantage of this default, and avoids even
saving <seclabel> elements with type='dynamic' to disk. This
means if you temporarily change security driver, the guests
can all still start.

With the introduction of sVirt to LXC though, there needs to be
a new default of 'none' to allow unconfined LXC containers.

This patch introduces two new security label types

 - default:  the host configuration decides whether to run the
             guest with type 'none' or 'dynamic' at guest start
 - none:     the guest will run unconfined by security policy

The 'none' label type will obviously be undesirable for some
deployments, so a new qemu.conf option allows a host admin to
mandate confined guests. It is also possible to turn off default
confinement

Qemu is adding the ability to do a partial rebase.  That is, given:

base <- intermediate <- current

virDomainBlockPull will produce:

current

but qemu now has the ability to leave base in the chain, to produce:

base <- current

Note that current qemu can only do a forward merge, and only with
the current image as the destination, which is fully described by
this API without flags.  But in the future, it may be possible to
enhance this API for additional scenarios by using flags:

Merging the current image back into a previous image (that is,
undoing a live snapshot), could be done by passing base as the
destination and flags with a bit requesting a backward merge.

Merging any other part of the image chain, whether forwards (the
backing image contents are pulled into the newer file) or backwards
(the deltas recorded in the newer file are merged back into the
backing file), could also be done by passing a new flag that says
that base should be treated as an XML snippet rather than an
absolute path name, where the XML could then supply the additional
instructions of which part of the image chain is being merged into
any other part.

The original doc entry for rawio didn't mention the values it could
have, the default, or the fact that setting it to "yes" for one disk
effectively set it to "yes" for all disks in the domain.

 This patch adds a new attribute "rawio" to the "disk" element
 of domain XML. Valid values of "rawio" attribute are "yes"
 and "no".
 rawio='yes' indicates the disk is desirous of CAP_SYS_RAWIO.

 If you specify the following XML:

 <disk type='block' device='lun' rawio='yes'>
  ...
 </disk>

 the domain will be granted CAP_SYS_RAWIO.
 (of course, the domain have to be executed with root privilege)

NOTE:
   - "rawio" attribute is only valid when device='lun'
   - At the moment, any other disks you won't use rawio can use rawio.

This patch addresses: https://bugzilla.redhat.com/show_bug.cgi?id=781562

Along with the "rombar" option that controls whether or not a boot rom
is made visible to the guest, qemu also has a "romfile" option that
allows specifying a binary file to present as the ROM BIOS of any
emulated or passthrough PCI device. This patch adds support for
specifying romfile to both passthrough PCI devices, and emulated
network devices that attach to the guest's PCI bus (just about
everything other than ne2k_isa).

One example of the usefulness of this option is described in the
bugzilla report: 82576 sriov network adapters don't provide a ROM BIOS
for the cards virtual functions (VF), but an image of such a ROM is
available, and with this ROM visible to the guest, it can PXE boot.

In libvirt's xml, the new option is configured like this:

   <hostdev>
     ...
     <rom file='/etc/fake/boot.bin'/>
     ...
   </hostdev

(similarly for <interface>).

When support for the rombar option was added, it was only added for
PCI passthrough devices, configured with <hostdev>. The same option is
available for any network device that is attached to the guest's PCI
bus. This patch allows setting rombar for any PCI network device type.

After adding cases to test this to qemuxml2argv-hostdev-pci-rombar.*,
I decided to rename those files (to qemuxml2argv-pci-rom.*) to more
accurately reflect the additional tests, and also noticed that up to
now we've only been performing a domainschematest for that case, so I
added the "pci-rom" test to both qemuxml2argv and qemuxml2xml (and in
the process found some bugs whose fixes I squashed into previous
commits of this series).

The domain schema enforced restrictions on the domain name string that
the code doesn't. This patch relaxes the check, leaving the restrictions
on the driver or hypervisor. The only invalid character is a newline.

It's better to group all the metadata together.  This is a
cosmetic output change; since the RNG allows interleave, it
doesn't matter where the user stuck it on input, and an XPath
query will find the same information when parsing the output.

Applications can now insert custom nodes and hierarchies into domain
configuration XML. Although currently not enforced, applications are
required to use their own namespaces on every custom node they insert,
with only one top-level element per namespace.

There is now a standard QEMU guest agent that can be installed
and given a virtio serial channel

    <channel type='unix'>
      <source mode='bind' path='/var/lib/libvirt/qemu/f16x86_64.agent'/>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
    </channel>

The protocol that runs over the guest agent is JSON based and
very similar to the JSON monitor. We can't use exactly the same
code because there are some odd differences in the way messages
and errors are structured. The qemu_agent.c file is based on
a combination and simplification of qemu_monitor.c and
qemu_monitor_json.c

This introduces new attribute wrpolicy with only supported
value as immediate. This will be an optional
attribute with no defaults. This helps specify whether
to skip the host page cache.

When wrpolicy is specified, meaning when wrpolicy=immediate
a writeback is explicitly initiated for the dirty pages in
the host page cache as part of the guest file write operation.

Usage:
<filesystem type='mount' accessmode='passthrough'>
  <driver type='path' wrpolicy='immediate'/>
  <source dir='/export/to/guest'/>
  <target dir='mount_tag'/>
</filesystem>

Currently this only works with type='mount' for the QEMU/KVM driver.
