I noticed that /var/lib/libvirt/dnsmasq/*.conf used the wrong word;
it was intended to match the wording in src/util/xml.c.

* src/network/bridge_driver.c (networkDnsmasqConfContents): Fix typo.
* tests/networkxml2confdata/*.conf: Update accordingly.

* Autotools changes:
  - Don't assume Qemu is Linux-only
  - Check Linux headers only on Linux
  - Disable firewalld on FreeBSD
* Initctl:
  Initctl seem to present only on Linux, so stub it on other platforms
* Raw I/O: Linux-only as well
* Headers cleanup

It's no longer used and also causes build fail on FreeBSD.

make check fails in check-symsorting if configure is not run in
the source directory. Prefixing symfile names with $(srcdir)
fixes this.

This patch adds a new domain lookup helper qemuDomObjFromDomainDriver
that lookups the domain and leaves the driver locked. The driver is
returned as the second argument of that function. If the lookup fails
the driver is unlocked to help avoid cleanup codepaths.

This patch also improves docs for the helpers.

I didn't notice the extra "does" in the previous patch. Remove it.

This patch gets rid of the undeterministic error reporting code done on
return values of get(pw|gr)nam_r. With this patch, if the group record
is not returned by the corresponding function this error is not
considered fatal even if errno != 0. The error is logged in such case.

Move the code for matching hostdev instances out of virDomainHostdevFind

Most of this deals with moving the libvirt-guests.sh script which

When using vnc gaphics over a unix socket, virt-aa-helper needs to provide
access for the qemu domain to access the sockfile.
Signed-off-by: NSerge Hallyn <serge.hallyn@ubuntu.com>

When a qemu domain is backed by huge pages, apparmor needs to grant the domain
rw access to files under the hugetlbfs mount point.  Add a hook, called in
qemu_process.c, which ends up adding the read-write access through
virt-aa-helper.  Qemu will be creating a randomly named file under the
mountpoint and unlinking it as soon as it has mmap()d it, therefore we
cannot predict the full pathname, but for the same reason it is generally
safe to provide access to $path/**.

I noticed that on Fedora 18, xlstproc decides to regenerate
HACKING with additional whitespace.  I haven't figured out why
that is happening (although fixing it would probably be a task
for xlstproc), but in the process of investigating, I noticed
that 'make HACKING' was completely silent, for no good reason.

Save and managedsave both use migration to file. This patch reuses
qemuMigrationIsAllowed to check if the migration could happen before
trying.

Qemu doesn't support migration on guests with host devices. This patch
adds a check to ensure migration is safe before actually doing so.

This patch exports qemuMigrationIsAllowed and adds a new parameter to it
to denote if it's a remote migration or a local migration. Local
migrations are used in snapshots and saving of the machine state and
have fewer restrictions. This patch also adjusts callers of the function
and tweaks some error messages to be more universal.

Currently there is no way to detect it via QMP and requesting "-sandbox
off" works correctly even if it was compiled out, so this will work
unless someone both requests the sandbox in qemu.conf and builds QEMU
without the support for it.

Interfaces keeps a class_id, which is an ID from which bridge
part of QoS settings is derived. We need to store class_id
in domain status file, so we can later pass it to
virNetDevBandwidthUnplug.

Currently, we are only keeping a inactive XML configuration
in status dir. This is no longer enough as we need to keep
this class_id attribute so we don't overwrite old entries
when the daemon restarts. However, since there has already
been release which has just <network/> as root element,
and we want to keep things compatible, detect that loaded
status file is older one, and don't scream about it.

Network should be notified if we plug in or unplug an
interface, so it can perform some action, e.g. set/unset
network part of QoS. However, we are doing this in very
early stage, so iface->ifname isn't filled in yet. So
whenever we want to report an error, we must use a different
identifier, e.g. the MAC address.

This will be used whenever a NIC with guaranteed throughput is to
be plugged into a bridge. It will adjust the average throughput of
non guaranteed NICs (classid 1:2) to meet new requirements.

These set bridge part of QoS when bringing domain's interface up.
Long story short, if there's a 'floor' set, a new QoS class is created.
ClassID MUST be unique within the bridge and should be kept for
unplug phase.

These classes can borrow unused bandwidth. Basically,
only egress qdsics can have classes, therefore we can
do this kind of traffic shaping only on host's outgoing,
that is domain's incoming traffic.

This is however supported only on domain interfaces with
type='network'. Moreover, target network needs to have at least
inbound QoS set. This is required by hierarchical traffic shaping.

From now on, the required attribute for <inbound/> is either 'average'
(old) or 'floor' (new). This new attribute can be used just for
interfaces type of network (<interface type='network'/>) currently.

Stochastic Fairness Queuing (SFQ) is queuing discipline
(qdisc) which doesn't really shape any traffic but 'just'
re-arrange packets in sending buffer so no stream starve.
The goal is to ensure fairness. There is basically only one
configuration parameter (perturb) which is set to advised
value of 10.

Network adapters of type 'routed' is a special case. Other adapters
have 'network' parameter in prlctl's output instead.

Routed network adapters should be connected to 'routed' network
from libvirt's view.

Historically if traffic from the adapter is routed to LAN without
NAT, it isn't connected to any virtual networks, but has a 'type'
instead. Sinse libvirt has special virtual network type for such case,
let's add pseudo network 'routed' to fit libvirt's API well.

Allow changing network interfaces in domain configuration.

ifname is used as iterface identifier: if there is interface
with some ifname in old config and there are no interfaces with
such name in the new config - issue prlctl command to delete

some ifname exists only in new config - issue prlctl command
to create it.
