af1b89d1d4 docs: Correct invalid hyperlinks
Since libvirt.h was split into multiple files and similarly
docs/libvirt-libvirt.html, docs/hvsupport.html have bad hyperlinks.  The
same happens for all the html.in files that used <code class='docref'>
tag, because page.xsl has no idea where to point the link that's found.

742d49fa17 qemu-command: introduce new vgamem attribute for QXL video device
Add attribute to set vgamem_mb parameter of QXL device for QEMU. This
value sets the size of VGA framebuffer for QXL device. Default value in
QEMU is 8MB so reuse it also in libvirt to not break things.

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.

401702d92e docs: Document NVRAM behavior on transient domains
Since 1.2.8 it's possible to use OVMF on domains. Moreover, it's
possible to have libvirt create NVRAM file per domain. Later,
when domain is undefined, the file is removed too. However,
things are a bit complicated when domain's transient. There's no
undefine to transient domains. There are two options: 1) leave
the file behind and let mgmt app remove it. 2) remove it
automatically as domain dies.
But, in some scenarios mgmt app may want to preserve the file,
copy it somewhere safe, and then copy it back when the domain is
starting again. And this wouldn't be possible with case 2). So,
even though case 1) leaves some files behind (possibly undeleted
for a long time), the files themselves are small (128K each). And
data loss is worse than full disk, isn't it?

17722c169c bhyve: Support /domain/bootloader configuration for non-FreeBSD guests.
We still default to bhyveloader(1) if no explicit bootloader
configuration is supplied in the domain.

If the /domain/bootloader looks like grub-bhyve and the user doesn't
supply /domain/bootloader_args, we make an intelligent guess and try
chainloading the first partition on the disk (or a CD if one exists,
under the assumption that for a VM a CD is likely an install source).

Caveat: Assumes the HDD boots from the msdos1 partition. I think this is
a pretty reasonable assumption for a VM. (DrvBhyve with Bhyveload
already assumes that the first disk should be booted.)

I've tested both HDD and CD boot and they seem to work.

07450cd429 conf: add trustGuestRxFilters attribute to network and domain interface
This new attribute will control whether or not libvirt will pay
attention to guest notifications about changes to network device mac
addresses and receive filters. The default for this is 'no' (for
security reasons). If it is set to 'yes' *and* the specified device
model and connection support it (currently only macvtap+virtio) then
libvirt will watch for NIC_RX_FILTER_CHANGED events, and when it
receives one, it will issue a query-rx-filter command, retrieve the
result, and modify the host-side macvtap interface's mac address and
unicast/multicast filters accordingly.

The functionality behind this attribute will be in a later patch. This
patch merely adds the attribute to the top-level of a domain's
<interface> as well as to <network> and <portgroup>, and adds
documentation and schema/xml2xml tests. Rather than adding even more
test files, I've just added the net attribute in various applicable
places of existing test files.

shared memory devices.  This will currently be only accessible in QEMU
using it's ivshmem device, but is designed as generic as possible to
allow future expansion for other hypervisors.

In the devices section in the domain XML users may specify:

- For shmem device using a server:

 <shmem name='shmem0'>
   <server path='/tmp/socket-ivshmem0'/>
   <size unit='M'>32</size>
   <msi vectors='32' ioeventfd='on'/>
 </shmem>

- For ivshmem device not using an ivshmem server:

 <shmem name='shmem1'>
   <size unit='M'>32</size>
 </shmem>

Most of the configuration is made optional so it also allows
specifications like:

 <shmem name='shmem1/>
 <shmem name='shmem2'>
   <server/>
 </shmem>

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.

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

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.

f1ac62f7ba doc: add domain to address of hostdev pci
libvirt supports pci domain already, so update the documentation.
Otherwise users who lookup the documentation for how to use hostdev may
miss the domain and encounter error when pass-through a pci device in a
domain other than 0.

2a48303800 doc: domain: Clarify that disk type 'lun' works with iSCSI too
Disk type 'lun' enables SCSI command passthrough for a disk. We stated
that it works only with "block" disks. Qemu supports it also when using
the iSCSI protocol.

3ba0469ce6 lxc network configuration allows setting target container NIC name
LXC network devices can now be assigned a custom NIC device name on the
container side. For example, this is configured with:

    <interface type='network'>
      <source network='default'/>
      <guest dev="eth1"/>
    </interface>

In this example the network card will appear as eth1 in the guest.
