The new TypedParam helper APIs allow to simplify this function
significantly.
This patch integrates the fix in 75e5bec97b
by correctly ordering the setting functions instead of reordering the
parameters.
The bridge device was showing the vnet devices created for the domains
as connected to the bridge. libvirt should only show host devices when
trying to get the interface definition rather than the domain devices as
well.

The uid_t|gid_t values are explicitly casted to "unsigned long", but the
printf() still used "%d", which is for signed values.
Change the format to "%u".

This patch adds a new capability bit QEMU_CAPS_OBJECT_RNG_EGD and code
to support the egd backend for the VirtIO RNG device.
The device is added by 3 qemu command line options:
-chardev socket,id=charrng0,host=1.2.3.4,port=1234 (communication
backend)
-object rng-egd,chardev=charrng0,id=rng0 (RNG protocol client)
-device virtio-rng-pci,rng=rng0,bus=pci.0,addr=0x4 (the RNG device)
This patch implements support for the virtio-rng-pci device and the
rng-random backend in qemu.
Two capabilities bits are added to track support for those:
QEMU_CAPS_DEVICE_VIRTIO_RNG - for the device support and
QEMU_CAPS_OBJECT_RNG_RANDOM - for the backend support.
qemu is invoked with these additional parameters if the device is
enabled:
-object rng-random,id=rng0,filename=/test/phile (to add the backend)
-device virtio-rng-pci,rng=rng0,bus=pci.0,addr=0x4 (to add the device)
This patch adds basic configuration support for the RNG device
supporting the virtio model with the "random" and "egd" backend types as
described in the schema in the previous patch.
This patch documents XML elements used for (basic) support of virtual
RNG devices.
In the devices section in the domain XML users may specify:
For the default 'random' backend:
<devices>
<rng model='virtio'>
<backend model='random'>/dev/urandom</backend>
</rng>
</devices>
For the slightly more advanced EGD backend:
<devices>
<rng model='virtio'>
<backend model='egd' type='udp'>
<!-- this is a definition of a character device -->
<source mode='bind' service='1234'/>
<source mode='connect' host='1.2.3.4' service='1234'/>
<!-- or other valid character device configuration -->
</backend>
</rng>
</devices>
For the planned random daemon/pool:
<devices>
<rng model='virtio'>
<backend model='pool' pool='poolname'>class</backend>
</rng>
</devices>
to enable the RNG device for guests.
This patch adds a fake switch statement to force the compiler to warn
after a new device type was added. This should remind the contributor to
add the new device also to this iterator function.
Originally, only a host name was used to associate a
DHCPv6 request with a specific IPv6 address. Further testing
demonstrates that this is an unreliable method and, instead,
a client-id or DUID needs to be used. According to DHCPv6
standards, this id can be a duid-LLT, duid-LL, or duid-UUID
even though dnsmasq will accept almost any text string.
Although validity checking of a specified string makes sure it is
hexadecimal notation with bytes separated by colons, there is no
rigorous check to make sure it meets the standard.
Documentation and schemas have been updated.

For really old qemu-img binaries which do not support specifying
the format of the backing file, display a DEBUG message instead of
INFO that this can't be done.
It makes no sense to prohibit reuse of the wrapper in other LGPL
projects, since most of libvirt is designed to be LGPL. Of
course, when using the wrapper to wrap a GPL program, the combined
result is still effectively GPL, but that shouldn't force us to
license the wrapper as GPL in isolation.
* run.in: Relicense to LGPLv2+.
This function does the source part of NBD magic. It
invokes drive-mirror on each non shared and RW disk with
a source and wait till the mirroring process completes.
When it does we can proceed with migration.
Currently, an active waiting is done: every 500ms libvirt
asks qemu if block-job is finished or not. However, once
the job finishes, qemu doesn't report its progress so we
can only assume if the job finished successfully or not.
The better solution would be to listen to the event which
is sent as soon as the job finishes. The event does
contain the result of job.
We need to start NBD server and feed it with all non-<shared/>,
RW and source-full disks. Moreover, with new virPortAllocator we
must ensure the borrowed port for NBD server will be returned if
either migration completes or qemu process is torn down.
This will be used with new migration scheme.
This patch creates basically just monitor stub
functions. Wiring them into something useful
is done in later patches.

This patch creates basically just monitor stub

This migration cookie is meant for two purposes. The first is to be sent
in begin phase from source to destination to let it know we support new
implementation of VIR_MIGRATE_NON_SHARED_{DISK,INC} so destination can
start NBD server. Then, the second purpose is, destination can let us
know, on which port the NBD server is running.
This patch adds support for a new <option>-Tag in the <dhcp> block of
network configs, based on a subset of the fifth proposal by Laine
Stump in the mailing list discussion at
https://www.redhat.com/archives/libvir-list/2012-November/msg01054.html.
Any such defined option will result in a dhcp-option=<number>,"<value>"
statement in the generated dnsmasq configuration file.
Currently, DHCP options can be specified by number only and there is
no whitelisting or blacklisting of option numbers, which should
probably be added.

Nothing in run required bash, except for the shebang. On systems
where /bin/bash doesn't exist (I hit it on FreeBSD), using /bin/sh
instead fixes a 'make check' failure:
gmake[3]: Entering directory `/usr/home/dummy/libvirt/python'
GEN check-local
/usr/local/bin/bash: ../run: /bin/bash: bad interpreter: No such file or directory
* run.in: Use /bin/sh, not bash.
The bfree and blocks fields are supposed to be in units of frsize. We were
calculating capacity correctly using those units, but the available
calculation was using bsize instead. Most file systems report these as the
same value specifically because many programs are buggy, but that is no
reason to rely on that behavior, or to behave inconsistently.
This bug has been present since e266ded (2008) and aa296e6c, when the code
was originally introduced (the latter via cut and paste).

On FreeBSD, I got a 'make check' failure:
GEN check-symsorting
Symbol block at ./libvirt_atomic.syms:4: viratomic.h not found
* src/Makefile.am (SYM_FILES): New define.
(check-symsorting): Check on all symfiles, even when not used.
* src/libvirt_atomic.syms: Fix offender.
As a side effect, this also fixes reporting disk migration process.
It was added to memory migration progress, which was wrong. Disk
progress has dedicated fields in virDomainJobInfo structure.
remoteDeserializeTypedParameters can now be called with either
preallocated params array (size of which is announced by nparams) or it
can allocate params array according to the number of parameters received
from the server.
