To prepare for introducing a single global driver, rename the
virDriver struct to virHypervisorDriver and the registration
API to virRegisterHypervisorDriver()
These tools have been rewritten upstream, so you don't need to link to
the old tools, link to the new ones and mention they are part of
libguestfs.
Also remove the link to "Poor man's P2V". There's no real reason to
use that technique any longer since the rewritten tools are simple,
fast and highly capable.
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.
This patch adds parsing/formatting code as well as documentation for
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>

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'.

Add options for tuning segment offloading:
<driver>
<host csum='off' gso='off' tso4='off' tso6='off'
ecn='off' ufo='off'/>
<guest csum='off' tso4='off' tso6='off' ecn='off' ufo='off'/>
</driver>
which control the respective host_ and guest_ properties
of the virtio-net device.
For the tap backend the default is specified and the same should be
done for the vhost attribute.

- docs/formatstorage.html.in: document 'zfs' pool type, add it
to a list of pool types that could use source physical devices
- docs/storage.html.in: update a ZFS pool example XML with
source physical devices, mention that starting from 1.2.9 a
pool could be created from this devices by libvirt and in earlier
versions user still has to create a pool manually
- docs/drvbhyve.html.in: add an example with ZFS pools
- Provide an implementation for buildPool and deletePool operations
for the ZFS storage backend.
- Add VIR_STORAGE_POOL_SOURCE_DEVICE flag to ZFS pool poolOptions
as now we can specify devices to build pool from
- storagepool.rng: add an optional 'sourceinfodev' to 'sourcezfs' and
add an optional 'target' to 'poolzfs' entity
- Add a couple of tests to storagepoolxml2xmltest
Check to see if the UEFI binary mentioned in qemu.conf actually
exists, and if so expose it in domcapabilities like

</loader>
We introduce some generic domcaps infrastructure for handling
a dynamic list of string values, it may be of use for future bits.

As of 542899168c we learned libvirt to use UEFI for domains.
However, management applications may firstly query if libvirt
supports it. And this is where virConnectGetDomainCapabilities()

I noticed this with the recent iothread pinning code, but the
problem existed longer than that. The XML validation required
users to supply <cputune> children in a strict order, even though
there was no conceptual reason why they can't occur in any order.

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.
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.

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.

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.

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.
