cdd362e0e7 storage: escape ipv6 for ceph mon hosts to librados
Hosts for rbd are ceph monitor daemons. These have fixed IP addresses,
so they are often referenced by IP rather than hostname for
convenience, or to avoid relying on DNS. Using IPv4 addresses as the
host name works already, but IPv6 addresses require rbd-specific
escaping because the colon is used as an option separator in the
string passed to librados.

Escape these colons, and enclose the IPv6 address in square brackets
so it is distinguished from the port, which is currently mandatory.

6394cf9768 network: convert hook script to take a network port XML
When (un)plugging an interface into a network, the 'plugged'
and 'unplugged' operations are invoked in the hook script.

The data provided to the script contains the network XML, the
domain XML and the domain interface XML. When we strictly split the
drivers up this will no longer be possible and thus breakage is
unavoidable. The hook scripts are not considered to be covered by the
API guarantee so this is OK.

To avoid existing scripts taking the wrong action, the existing
operations are changed to 'port-created' and 'port-deleted'
instead. These will receive the network XML and the network port
XML.

18006c696d gitdm: Add gitdm configuration
This configuration can be used by gitdm to generate reports about
libvirt development.

The goal I was working with was being able to generate a report
for every single libvirt release and having zero "email address
as company" entries; picking different commit ranges might result
in some contributions not being accounted for.

I had to make some judgement calls when the situation was not
entirely clear-cut: when in doubt, and not finding any obvious
signs of the opposite being true, I mostly ended up dumping
people in the "unaffiliated contributions" bin. If I got it
wrong, and companies want to get recognition for their sponsored
contributions to libvirt, they can send patches.

a007fcab3b snapshot: Don't expose testsuite-only state in snapshot XML
None of the existing drivers actually use the 0-valued 'nostate'
snapshot state; rather, it was a fluke of implementation. In fact,
some drivers, like qemu, actively reject 'nostate' as invalid during a
snapshot redefine. Normally, a driver computes the state post-parse
from the current domain, and thus virDomainSnapshotGetXMLDesc() will
never expose the state. However, since the testsuite lacks any
associated domain to copy state from, and lacks post-parse processing
that normal drivers have, the testsuite output had several spots with
the state, coupled with a regex filter to ignore the oddity.

It is better to follow the lead of other XML defaults, by not
outputting anything during format if post-parse defaults have not been
applied, and rejecting the default value during parsing. The testsuite
needs a bit of an update, by adding another flag for when to simulate
a post-parse action of setting a snapshot state, but none of the
drivers are impacted other than rejecting XML that was previously
already suspicious in nature.

Similarly, don't expose creation time 0 (for now, only possible if a
user redefined a snapshot to claim creation at the Epoch, but also
happens once setting the creation time is deferred to a post-parse
handler).

This is also a step towards cleaning up snapshot_conf.c to separate
its existing post-parse work (namely, setting the creationTime and
default snapshot name) from the pure parsing work, so that we can get
rid of the testsuite hack of regex filtering of the XML and instead
have more accurate testing of our parser/formatter code.

5b9819eedc domain capabilities: Expose firmware auto selection feature
If a management application wants to use firmware auto selection
feature it can't currently know if the libvirtd it's talking to
support is or not. Moreover, it doesn't know which values that
are accepted for the @firmware attribute of <os/> when parsing
will allow successful start of the domain later, i.e. if the mgmt
application wants to use 'bios' whether there exists a FW
descriptor in the system that describes bios.

This commit then adds 'firmware' enum to <os/> element in
<domainCapabilities/> XML like this:

  <enum name='firmware'>
    <value>bios</value>
    <value>efi</value>
  </enum>

We can see both 'bios' and 'efi' listed which means that there
are descriptors for both found in the system (matched with the
machine type and architecture reported in the domain capabilities
earlier and not shown here).

4e797f1af9 conf: Parse and format 'backingStore' for disk <mirror>
When the block copy operation is started with a reused external file in
incremental mode libvirt will need to open and insert the backing chain
for that file into qemu (in -blockdev mode). This means that we'll need
to track the backing chain and metadata such as node names for the full
chain of <mirror>.

This patch invokes the full backing chain formatter and parser for
<mirror> so that the chain can be kept with <mirror>.

a6a25d5cb6 snapshot: More clarification about REDEFINE
Based on recent list questions about the proposed addition of
virDomainCheckpointCreateXML(REDEFINE), it is worth adding some
clarification to the existing snapshot redefine documentation that is
serving as the basis for checkpoints.

Normal snapshot creation requires very few elements from the user XML
(libvirt can pick sane defaults for items that are omitted, and many
fields, including <domain>, are documented as readonly output fields
ignored on input, produced by drivers that track it). But during
REDEFINE, the API wants the complete XML produced by an earlier
virDomainSnapshotGetXMLDesc; as the domain definition has likely
changed since the snapshot was first created, libvirt is unable to
recreate a <domain> sub-element that matches the original output
representing the domain state at the time the snapshot was first
created. In fact, reverting without a <domain> sub-element is risky
enough that we had to add a FORCE flag for virDomainSnapshotRevert().
In short, we only support omitting domain for qemu because of
backwards-compatibility to snapshots created before 0.9.5 started
capturing <domain>; even though there are other drivers like vbox that
do not output <domain> because they have other reliable ways to
revert.

And based on the confusion caused when omitting <domain> from snapshot
XML, the initial design for checkpoints in later patches will make
<domain> a mandatory element during its REDEFINE.

[Side note: the fact that <domain> can appear in <domainsnapshot> is a
reason we cannot add a new API for a bulk listing or redefine of all
snapshots of a single domain in one XML call (for example, a 1M
<domain> XML * 16 snapshots explodes into 16M in a bulk form, which
gets difficult to send over RPC). Perhaps we could add a flag to
request that the <domain> sub-element be omitted on output, but such
output is no longer suitable for sane REDEFINE input.]

09eb1ae0ec conf: Add a new 'xenbus' controller type
xenbus is virtual controller (akin to virtio controllers) for Xen
paravirtual devices. Although all Xen VMs have a xenbus, it has
never been modeled in libvirt, or in Xen native VM config format
for that matter.

Recently there have been requests to support Xen's max_grant_frames
setting in libvirt. max_grant_frames is best modeled as an attribute
of xenbus. It describes the maximum IO buffer space (or DMA space)
available in xenbus for use by connected paravirtual devices. This
patch introduces a new xenbus controller type that includes a
maxGrantFrames attribute.

d947fa8a08 conf: Introduce firmware attribute to <os/>
The idea is that using this attribute users enable libvirt to
automagically select firmware image for their domain. For
instance:

  <os firmware='efi'>
    <type arch='x86_64' machine='pc-q35-4.0'>hvm</type>
    <loader secure='no'/>
  </os>

  <os firmware='bios'>
    <type arch='x86_64' machine='pc-q35-4.0'>hvm</type>
  </os>

(The automagic of selecting firmware image will be described in
later commits.)

Accepted values are 'bios' and 'efi' to let libvirt select
corresponding type of firmware.

I know it is a good sign to introduce xml2xml test case when
changing XML config parser but that will have to come later.
Firmware auto selection is not enabled for any driver just yet so
any xml2xml test would fail right away.

d152c727c6 snapshots: Avoid term 'checkpoint' for full system snapshot
Upcoming patches plan to introduce virDomainCheckpointPtr as a new
object for use in incremental backups, along with documentation on
how incremental backups differ from snapshots.  But first, we need
to rename any existing mention of a 'system checkpoint' to instead
be a 'full system snapshot', so that we aren't overloading
the term checkpoint.

b71de701b8 conf: introduce 'msrs' feature
Introduce the 'msrs' feature element that controls Model Specific
Registers related behaviour. At this moment it allows only
single tunable attribute "unknown":

 <msrs unknown='ignore|fault'/>

Which tells hypervisor to ignore accesses to unimplemented
Model Specific Registers. The only user of that for now is going
to be the bhyve driver.

30a6f91686 network: allow configuring firewalld zone for virtual network bridge device
Since we're setting the zone anyway, it will be useful to allow
setting a different (custom) zone for each network. This will be done
by adding a "zone" attribute to the "bridge" element, e.g.:

   ...
   <bridge name='virbr0' zone='myzone'/>
   ...

If a zone is specified in the config and it can't be honored, this
will be an error.

ae05211a36 network: set firewalld zone of bridges to "libvirt" zone when appropriate
This patch restores broken guest network connectivity after a host
firewalld is switched to using an nftables backend. It does this by
adding libvirt networks' bridge interfaces to the new "libvirt" zone
in firewalld.

After this patch, the bridge interface of any network created by
libvirt (when firewalld is active) will be added to the firewalld
zone called "libvirt" if it exists (regardless of the firewalld
backend setting). This behavior does *not* depend on whether or not
libvirt has installed the libvirt zone file (set with
"--with[out]-firewalld-zone" during the configure phase of the package
build).

If the libvirt zone doesn't exist (either because the package was
configured to not install it, or possibly it was installed, but
firewalld doesn't support rule priorities, resulting in a parse
error), the bridge will remain in firewalld's default zone, which
could be innocuous (in the case that the firewalld backend is
iptables, guest networking will still function properly with the
bridge in the default zone), or it could be disastrous (if the
firewalld backend is nftables, we can be assured that guest networking
will fail). In order to be unobtrusive in the former case, and
informative in the latter, when the libvirt zone doesn't exist we
then check the firewalld version to see if it's new enough to support
the nftables backend, and then if the backend is actually set to
nftables, before logging an error (and failing the net-start
operation, since the network couldn't possibly work anyway).

When the libvirt zone is used, network behavior is *slightly*
different from behavior of previous libvirt. In the past, libvirt
network behavior would be affected by the configuration of firewalld's
default zone (usually "public"), but now it is affected only by the
"libvirt" zone), and thus almost surely warrants a release note for
any distro upgrading to libvirt 5.1 or above. Although it's
unfortunate that we have to deal with a mandatory behavior change, the
architecture of multiple hooks makes it impossible to *not* change
behavior in some way, and the new behavior is arguably better (since
it will now be possible to manage access to the host from virtual
machines vs from public interfaces separately).
