d7a4a9b2ff formatdomain.html.in: Document implementation limitation of QoS
The outbound/@peak is ignored (since QoS was introduced). This is due to
kernel limitation of know allowing ingress filters to have peak just
average rate. However, we should document this limitation to not confuse
users.

Interestingly, we had <code>floor<code> ... </code>outbound</code> which
results in much larger block of text to be written in code style that

c00b2f0dd1 conf: Introduce new XML tag "mode" for disk source
There are two ways to use a iSCSI LUN as disk source for qemu.

 * The LUN's path as it shows up on host, e.g.
   /dev/disk/by-path/ip-$ip:3260-iscsi-$iqn-fc18:iscsi.iscsi0-lun-1

 * The libiscsi URI from the storage pool source element host attribute, e.g.
   iscsi://demo.org:6000/iqn.1992-01.com.example/1

For a "volume" type disk, if the specified "pool" is of iscsi
type, we should support to use the LUN in either of above 2 ways.
That's why to introduce a new XML tag "mode" for the disk source
(libvirt should support iscsi pool with libiscsi, but it's another
new feature, which should be done later).

The "mode" can be either of "host" or "direct". Use "host" to indicate
use of the LUN with the path as it shows up on host. Use "direct" to
indicate to use it with the source pool host URI (future patches may support
to use network type libvirt storage too, e.g. Ceph)

Makefiles are another easy file to enforce line limits.

Mostly straightforward; interesting tricks worth noting:

eb0d79c64b storage_pool: Rework chap XML to mimic ceph
The existing 'chap' XML logic was never used - just defined.  Rather than
try to insert a square peg into a round hole, blow it up and rewrite the
logic to follow the 'ceph' format.

Remove the former "chap.login" and "chap.passwd" fields and replace
with "chap.username" and "chap.secret" in _virStoragePoolAuthChap.
Adjust the virStoragePoolDefParseAuthChap() to process.

Change the rng file to describe the new layout

Update the formatstorage.html to describe the usage of the secret element
to mention that the secret type "iscsi" and "ceph" can be used
to storage pool too.

Update the formatsecret.html to include a reference to the storage pool

Update tests to handle the changes from 'login' and 'passwd' to 'username'
and '<secret>' format

1e503ee534 build: honor autogen.sh --no-git
Based on a report by Chandrashekar Shastri, at
https://bugzilla.redhat.com/show_bug.cgi?id=979360

On systems where git cannot access the outside world, a developer
can instead arrange to get a copy of gnulib at the right commit
via side channels (such as NFS share drives), set GNULIB_SRCDIR,
then use ./autogen.sh --no-git.  In this setup, we will now
avoid direct use of git.  Of course, this means no automatic
gnulib updates when libvirt.git updates its submodule, but it
is expected that any developer in such a situation is already
prepared to deal with the fallout.

* .gnulib: Update to latest, for bootstrap.
* bootstrap: Synchronize from gnulib.
* autogen.sh (no_git): Avoid git when requested.
* cfg.mk (_update_required): Skip automatic rerun of bootstrap if
we can't use git.
* docs/compiling.html.in: Document this setup.
* docs/hacking.html.in: Mention this.
* HACKING: Regenerate.

this new element is used for setting proc files

49e6a16f82 Document security reporting & handling process
Historically security issues in libvirt have been primarily
triaged & fixed by the Red Hat libvirt members & Red Hat
security team, who then usually notify other vendors via
appropriate channels. There have been a number of times
when vendors have not been properly notified ahead of
announcement. It has also disadvantaged community members
who have to backport fixes to releases for which there are
no current libvirt stable branches.

To address this, we want to make the libvirt security process
entirely community focused / driven. To this end I have setup
a new email address "libvirt-security@redhat.com" for end
users to report bugs which have (possible) security implications.

This email addr is backed by an invitation only, private
archive, mailing list. The intent is for the list membership
to comprise a subset of the libvirt core team, along with any
vendor security team engineers who wish to participate in a
responsible disclosure process for libvirt. Members of the
list will be responsible for analysing the problem to determine
if a security issue exists and then issue fixes for all current
official stable branches & git master.

I am proposing the following libvirt core team people as
members of the security team / list (all cc'd):

   Daniel Berrange (Red Hat)
   Eric Blake (Red Hat)
   Jiri Denemar (Red Hat)
   Daniel Veillard (Red Hat)
   Jim Fehlig (SUSE)
   Doug Goldstein (Gentoo)
   Guido Günther (Debian)

We don't have anyone from Ubuntu on the libvirt core team.
Serge Hallyn is the most frequent submitter of patches from
Ubuntu in recent history, so I'd like to invite him to join.
Alternatively, Serge, feel free to suggest someone else to
represent Ubuntu's interests.

If any other vendors/distros have security people who are
responsible for dealing with libvirt security issues, and
want to join to get early disclosure of issues, they can
suggest people. Existing security team members will vet /
approve such requests to ensure they are genuine.

Anyone on the team / list will be **required** to honour any
embargo period agreed between members for non-public issues
that are reported. The aim will be to have a maximum 2 week
embargo period in the common case, extendable to 1 month if
there is sufficient justification made. If anyone feels they
are unable to follow such an embargo process for whatever
reason, please decline membership of the security list/team.

The patch which follows puts up some docs on the website
about all of this....

Document how to report security bugs and the process that
will be used for addressing them.

This patch exposes the support in libvirt.

QEMU supported "discard" for "-drive" since v1.5.0-rc0:

% git tag --contains a9384aff53
contains
v1.5.0-rc0
v1.5.0-rc1

So this only detects the capability bit using virQEMUCapsProbeQMPCommandLine.

QEMU introduced command line "-mem-merge=on|off" (defaults to on) to
enable/disable the memory merge (KSM) at guest startup. This exposes
it by new XML:

ccff335f83 Support for static routes on a virtual bridge
network: static route support for <network>

This patch adds the <route> subelement of <network> to define a static
route.  the address and prefix (or netmask) attribute identify the
destination network, and the gateway attribute specifies the next hop
address (which must be directly reachable from the containing
<network>) which is to receive the packets destined for
"address/(prefix|netmask)".

These attributes are translated into an "ip route add" command that is
executed when the network is started. The command used is of the
following form:

  ip route add <address>/<prefix> via <gateway> \
               dev <virbr-bridge> proto static metric <metric>

Tests are done to validate that the input data are correct.  For
example, for a static route ip definition, the address must be a
network address and not a host address.  Additional checks are added
to ensure that the specified gateway is directly reachable via this
network (i.e. that the gateway IP address is in the same subnet as one
of the IP's defined for the network).

prefix='0' is supported for both family='ipv4' address='0.0.0.0'
netmask='0.0.0.0' or prefix='0', and for family='ipv6' address='::',
prefix=0', although care should be taken to not override a desired
system default route.

Anytime an attempt is made to define a static route which *exactly*
duplicates an existing static route (for example, address=::,
prefix=0, metric=1), the following error message will be sent to
syslog:

    RTNETLINK answers: File exists

This can be overridden by decreasing the metric value for the route
that should be preferred, or increasing the metric for the route that
shouldn't be preferred (and is thus in place only in anticipation that
the preferred route may be removed in the future).  Caution should be
used when manipulating route metrics, especially for a default route.

Note: The use of the command-line interface should be replaced by
direct use of libnl so that error conditions can be handled better.  But,
that is being left as an exercise for another day.

ada14b86cc Add support for storage format in FS <driver>
Extend the <driver> element in filesystem devices to
allow a storage format to be set. The new attribute
uses 'format' to reflect the storage format. This is
different from the <driver> element in disk devices
which use 'type' to reflect the storage format. This
is because the 'type' attribute on filesystem devices
is already used for the driver backend, for which the
disk devices use the 'name' attribute. Arggggh.

Anyway for disks we have

   <driver name="qemu" type="raw"/>

And for filesystems this change means we now have

   <driver type="loop" format="raw"/>

5c811dcec5 conf: Generic XMLs for scsi hostdev
An example of the scsi hostdev XML:

    <hostdev mode='subsystem' type='scsi'>
      <source>
        <adapter name='scsi_host0'/>
        <address bus='0' target='0' unit='0'/>
      </source>
      <address type='drive' controller='0' bus='0' target='4' unit='8'/>
    </hostdev>

Controller is implicitly added for scsi hostdev, though the scsi
controller's model defaults to "lsilogic", which might be not what
the user wants (same problem exists for virtio-scsi disk). It's
the existing problem, will be addressed later.

The device address must be specified manually. Later patch will let
libvirt generate it automatically.

This only introduces the generic XMLs for scsi hostdev, later patches
will add other elements, e.g. <readonly>, <shareable>.

6b74a9f5d9 string: make VIR_STRDUP easier to use
While reviewing proposed VIR_STRDUP conversions, I've already noticed
several places that do:

if (str && VIR_STRDUP(dest, str) < 0)

which can be simplified by allowing str to be NULL (something that
strdup() doesn't allow).  Meanwhile, code that wants to ensure a
non-NULL dest regardless of the source can check for <= 0.

Also, make it part of the VIR_STRDUP contract that macro arguments
are evaluated exactly once.

c4f63ef080 conf: formatter/parser/RNG/docs for hostdev <driver name='kvm|vfio'/>
A domain's <interface> or <hostdev>, as well as a <network>'s
<forward>, can now have an optional <driver name='kvm|vfio'/>
element. As of this patch, there is no functionality behind this new
knob - this patch adds support to the domain and network
formatter/parser, and to the RNG and documentation.

When the backend is added, legacy KVM PCI device assignment will
continue to be used when no driver name is specified (or if <driver
name='kvm'/> is specified), but if driver name is 'vfio', the new UEFI
Secure Boot compatible VFIO device assignment will be used.

Note that the parser doesn't automatically insert the current default
value of this setting. This is done on purpose because the two
possibilities are functionally equivalent from the guest's point of
view, and we want to be able to automatically start using vfio as the
default (even for existing domains) at some time in the future. This
is similar to what was done with the "vhost" driver option in
<interface>.

types of controllers allowed which models, and also allowed the
num_queues attribute (since that hasn't been released yet, should we

allowed only for type='scsi', and <master> only for type='usb'.

This patch makes a separate <group> for type='scsi' and type='usb',
with each group allowing only the appropriate model values, and
allowing num_queue and <master> only when appropriate.

<interleave> also hadn't been specified, forcing a specific order of

Attribute 'type' can be either 'scsi_host' or 'fc_host', and defaults
to 'scsi_host' if attribute 'name' is specified. I.e. It's optional
for 'scsi_host' adapter, for back-compat reason. However, mandatory
for 'fc_host' adapter and any new future adapter types. Attribute
'parent' is to specify the parent for the fc_host adapter.

1a308ee015 qemu: add support for libiscsi
libiscsi provides a userspace iSCSI initiator.

The main advantage over the kernel initiator is that it is very
easy to provide different initiator names for VMs on the same host.
Thus libiscsi supports usage of persistent reservations in the VM,
which otherwise would only be possible with NPIV.

libiscsi uses "iscsi" as the scheme, not "iscsi+tcp".  We can change
this in the tests (while remaining backwards-compatible manner, because
QEMU uses TCP as the default transport for both Gluster and NBD).

28933c5574 Correct invalid RNG schemas
The 'trang' utility, which is able to transform '.rng' files into
'.rnc' files, reported some errors in our schemas that weren't caught
by the tools we use in the build.  I haven't added a test for this,
but the validity can be checked by the following command:

trang -I rng -O rnc domain.rng domain.rnc

There were unescaped minuses in regular expressions and we were
constraining int (which is by default in the range of [-2^31;2^31-1]
to maximum of 2^32.  But what we wanted was exactly an unsignedInt.

32bd699f55 virtio-rng: Add rate limiting options for virtio-RNG
Qemu's implementation of virtio RNG supports rate limiting of the
entropy used. This patch exposes the option to tune this functionality.

This patch is based on qemu commit 904d6f588063fb5ad2b61998acdf1e73fb4

The rate limiting is exported in the XML as:
<devices>
  ...
  <rng model='virtio'>
    <rate bytes='123' period='1234'/>
    <backend model='random'/>
  </rng>

41ce2c9e94 S390: Documentation for CCW address type
The native bus for s390 I/O is called CCW (channel command word).
As QEMU has added basic support for the CCW bus, i.e. the
ability to assign CCW devnos (bus addresses) to devices.
Domains with the new machine type s390-ccw-virtio can use the
CCW bus. Currently QEMU will only allow to define virtio
devices on the CCW bus.
Here we add the new machine type and the new device address to the
schema definition and add a new paragraph to the domain XML
documentation.

4932ef4502 rng: restrict passthrough names to known-good files
There is some controversy[1] on the qemu list on whether qemu should
have ever allowed arbitrary file name passthrough, or whether it
should be restricted to JUST /dev/random and /dev/hwrng.  It is
always easier to add support for additional filenames than it is
to remove support for something once released, so this patch
restricts libvirt 1.0.3 (where the virtio-random backend was first
supported) to just the two uncontroversial names, letting us defer
to a later date any decision on whether supporting arbitrary files
makes sense. Additionally, since qemu 1.4 does NOT support
/dev/fdset/nnn fd passthrough for the backend, limiting to just
two known names means that we don't get tempted to try fd
passthrough where it won't work.
