Since virNetServerAddClient checks for the limits in order to temporarily
suspend the services, thus not accepting any more clients, there is no reason
why virNetServerCheckLimits, which is only responsible for re-enabling
previously disabled services according to the limits, could not do both. To be
able to do that however, it needs to be moved up in the file since it's static
(and because it's just a helper and there's only one caller it should remain
 static).

Introduce libxl hook and use it for start, prepare, started,
stop, stopped, migrate events.

In case of error, libxlReconnectDomain may call
virDomainObjListRemoveLocked. However it has no local reference on
the domain object, leading to segfault. Get a reference to the domain
object at the start of the function and release it at the end to avoid
problems.

This commit also factorizes code between the error and normal ends.

The migrate hook will affect the migrated guest definition. Allow
these domains be marked as tainted in the libxl driver.

To sync with virDomainControllerModelUSB, we add two models
in qemuControllerModelUSB 'qusb1' and 'qusb2', but those
models are not supported in qemu driver. So add check in
device post parse to report errors if 'qusb1' and 'qusb2'
are specified.

According to libxl implementation, it supports pvusb
controller of version 1.1 and version 2.0, and it
supports two types of backend, 'pvusb' (dom0 backend)
and 'qusb' (qemu backend). But currently pvusb backend
is not checked in yet.

To match libxl support, extend usb controller schema
to support two more models: qusb1 (qusb, version 1.1)
and 'qusb2' (qusb version 2.0).

Construct the query string by using virBufferTrim rather than having to
remember to add a space and simplify cleanup path.

Use a temporary pointer rather than always recalculating the index in a
very verbose way.

Add a structure to store the data and use a single array of the
structures rather than having 3 separate arrays with shared indexes.

Let's cleanly differentiate what wiping a volume does for ploop and

When wiping a volume we just rewrite all the data of the volume, not
only the content.  Since format gets overridden, we need to recreate the
volume.  However we can't do that for every possible format out there.
Since it was only coded for the ploop volume type, let's document what
might be the consequences instead of forbidding it for every other
format out there.

  This patch reflects cases when <interface> element and its <source>
subelement for network type are formated based on actual type resolved
from referenced network instead of original one. networkAllocateActualDevice
and virDomainActualNetDefContentsFormat are taken as reference.

Ever since virDomainCreateWithFlags() was introduced by de3aadaa
[drivers: add virDomainCreateWithFlags if virDomainCreate exists], the
domain ID retrieved with virDomainGetID() was incorrect for several
drivers after virDomainCreateWithFlags() was called. The API consumer
had to look up the domain anew to retrieve the correct ID.

For the ESX driver, this was fixed in 6139b274 [esx: Update ID after
starting a domain]. For the openvz driver, it was fixed in fd81a097
[openvzDomainCreateWithFlags: set domain id to the correct value]. The
test driver, the OpenNebula driver (removed in the meantime) and the
vbox driver were already updating the domain ID correctly in
domainCreate().

Copy over the ID in qemuDomainCreateWithFlags() to fix this for the qemu
driver, too.

Whats wrong you ask? The @model attribute. This should result in
an error thrown into users faces during virDomainDefine phase.
Except it doesn't. The XML validation catches this error, but if
users chose to ignore that, they will end up with invalid XML.
Well, they won't be able to start the machine - that's when error
is produced currently. But it would be nice if we could catch the

The original name 'admin_uri_default' was introduced to our code by commit
dbecb87f. However, at that time we already had a separate config file for
admin library but the commit mentioned above didn't properly adjust the
config's option name. The result is that when we're loading the config, we
check a non-existent config option (there's not much to do with the URIs
anyway, since we only allow local connection). Additionally, virt-admin's man
page documents, that the default URI can be altered by setting
admin_uri_default option. So the fix proposed by this patch leaves the
libvirt-admin.conf as is and adjusts the naming in the code as well as in the
virt-admin's man page.
