1be67cd31b storage: Fix logical pool fmt type
According to our documentation logical pool supports formats 'auto' and
'lvm2'. However, in storage_conf.c we previously defined storage pool
formats: unknown, lvm2. Due to backward compatibility reasons
we must continue refer to pool format type 'unknown' instead of 'auto'.

Check to see if the UEFI binary mentioned in qemu.conf actually

7e8feed4a7 cputune: allow interleaved xml
I noticed this with the recent iothread pinning code, but the

there was no conceptual reason why they can't occur in any order.

938fb12fad domain_conf: Add iothreadpin to cputune
https://bugzilla.redhat.com/show_bug.cgi?id=1101574

Add an option 'iothreadpin' to the <cpuset> to allow for setting the
CPU affinity for each IOThread.

The iothreadspin will mimic the vcpupin with respect to being able to
assign each iothread to a specific CPU, although iothreads ids start
at 1 while vcpu ids start at 0. This matches the iothread naming scheme.

3aa0524104 network: check for invalid forward delay time
When spanning tree protocol is allowed in bridge settings, forward delay
value is set as well (default is 0 if omitted). Until now, there was no
check for delay value validity. Delay makes sense only as a positive
numerical value.

Note: However, even if you provide positive  numerical value, brctl
utility only uses values from range <2,30>, so the number provided can
be modified (kernel most likely) to fall within this range.

dcf7d0423c formatdomain: Update <loader/> example to match the rest
At the beginning when I was inventing <loader/> attributes and
<nvram/> I've introduced this @readonly attribute to the loader
element. It accepted values 'on' and 'off'. However, later, during the
review process, that has changed to 'yes' and 'no', but the example
XML snippet wasn't updated, so while the description is correct, the
example isn't.

742b08e30f qemu: Automatically create NVRAM store
When using split UEFI image, it may come handy if libvirt manages per
domain _VARS file automatically. While the _CODE file is RO and can be
shared among multiple domains, you certainly don't want to do that on
the _VARS file. This latter one needs to be per domain. So at the
domain startup process, if it's determined that domain needs _VARS
file it's copied from this master _VARS file. The location of the
master file is configurable in qemu.conf.

Temporary, on per domain basis the location of master NVRAM file can
be overridden by this @template attribute I'm inventing to the
<nvram/> element. All it does is holding path to the master NVRAM file
from which local copy is created. If that's the case, the map in
qemu.conf is not consulted.

68bf13dbef conf: Extend <loader/> and introduce <nvram/>
Up to now, users can configure BIOS via the <loader/> element. With
the upcoming implementation of UEFI this is not enough as BIOS and
UEFI are conceptually different. For instance, while BIOS is ROM, UEFI
is programmable flash (although all writes to code section are
denied). Therefore we need new attribute @type which will
differentiate the two. Then, new attribute @readonly is introduced to
reflect the fact that some images are RO.

Moreover, the OVMF (which is going to be used mostly), works in two
modes:
1) Code and UEFI variable store is mixed in one file.
2) Code and UEFI variable store is separated in two files

The latter has advantage of updating the UEFI code without losing the
configuration. However, in order to represent the latter case we need
yet another XML element: <nvram/>. Currently, it has no additional
attributes, it's just a bare element containing path to the variable
store file.

hypervisor to load.  Domain XML syntax is as follows:

0257d06ba4 storage: ZFS support
Implement ZFS storage backend driver. Currently supported
only on FreeBSD because of ZFS limitations on Linux.

Features supported:

 - pool-start, pool-stop
 - pool-info
 - vol-list
 - vol-create / vol-delete

Pool definition looks like that:

 <pool type='zfs'>
  <name>myzfspool</name>
  <source>
    <name>actualpoolname</name>
  </source>
 </pool>

The 'actualpoolname' value is a name of the pool on the system,
such as shown by 'zpool list' command. Target makes no sense
here because volumes path is always /dev/zvol/$poolname/$volname.

User has to create a pool on his own, this driver doesn't
support pool creation currently.

A volume could be used with Qemu by adding an entry like this:

    <disk type='volume' device='disk'>
      <driver name='qemu' type='raw'/>
      <source pool='myzfspool' volume='vol5'/>
      <target dev='hdc' bus='ide'/>

54ac483e68 hostdev: Add iSCSI hostdev XML
Introduce a new structure to handle an iSCSI host device based on the
existing virDomainHostdevSubsysSCSI by adding a "protocol='iscsi'" to
the <source/> element. The existing scsi_host subsystem RNG was modified
to read an optional "protocol='adapter'", although it won't be written
out nor is it documented as an option (by choice).

The new hostdev structure mimics the existing <disk/> element for an
iSCSI device (network) device. New XML is:

  <hostdev mode='subsystem' type='scsi' managed='yes'>
    <source protocol='iscsi' name='iqn.1992-01.com.example'>
      <host name='example.org' port='3260'/>

      </auth>
    </source>
    <address type='drive' controller='0' bus='0' target='2' unit='5'/>
  </hostdev>

The controller element will mimic the existing scsi_host code insomuch
as when 'lsi' and 'virtio-scsi' are used.

232a31bea3 blockcommit: track job type in xml
A future patch is going to wire up qemu active block commit jobs;
but as they have similar events and are canceled/pivoted in the
same way as block copy jobs, it is easiest to track all bookkeeping
for the commit job by reusing the <mirror> element.  This patch
adds domain XML to track which job was responsible for creating a
mirroring situation, and adds a job='copy' attribute to all
existing uses of <mirror>.  Along the way, it also massages the
qemu monitor backend to read the new field in order to generate
the correct type of libvirt job (even though it requires a
future patch to actually cause a qemu event that can be reported
as an active commit).  It also prepares to update persistent XML
to match changes made to live XML when a copy completes.

9a212d6708 blockcopy: add more XML for state tracking
Doing a blockcopy operation across a libvirtd restart is not very
robust at the moment.  In particular, we are clearing the <mirror>
element prior to telling qemu to finish the job.  Also, thanks to the
ability to request async completion, the user can easily regain
control prior to qemu actually finishing the effort, and they should
be able to poll the domain XML to see if the job is still going.

A future patch will fix things to actually wait until qemu is done
before modifying the XML to reflect the job completion.  But since
qemu issues identical BLOCK_JOB_COMPLETE events regardless of whether
the job was cancelled (kept the original disk) or completed (pivoted
to the new disk), we have to track which of the two operations were
used to end the job.  Furthermore, we'd like to avoid attempts to
end a job where we are already waiting on an earlier request to qemu
to end the job.  Likewise, if we miss the qemu event (perhaps because
it arrived during a libvirtd restart), we still need enough state
recorded to be able to determine how to modify the domain XML once
we reconnect to qemu and manually learn whether the job still exists.

Although this patch doesn't actually fix the problem, it is a
preliminary step that makes it possible to track whether a job
has already begun steps towards completion.
