Commit 0b36b0e9 broke polkit agent startup when attempting to fix a
coverity warning. Refactor it properly so that we don't need the 'cmd'
intermediate variable.
qemuDomainCheckDiskPresence has short-circuit code to skip the
determination of the disk backing chain for storage formats that can't
have backing volumes. The code treats VIR_STORAGE_FILE_NONE as not
having backing chain and skips the call to qemuDomainDetermineDiskChain.
This is wrong as qemuDomainDetermineDiskChain is responsible for storage
format detection and has logic to determine the default type if format
detection is disabled.
This allows to storage passed via <disk type="volume"> to circumvent the
enforcement to have correct storage format or that we shall default to
format='raw', since we don't set the default type via the post parse
callback for "volume" backed disks as the translation code could come up
with a better guess.

Extract the relevant parts of the existing checker and reuse them for
blockcopy since copying to a non-block device creates an invalid
configuration.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1209802
In qemuCheckDiskConfig would now use virDomainDiskSourceIsBlockType just
as a glorified version of virStorageSourceIsBlockLocal that reports
error messages. Replace it with the latter including the message for
clarity.
Commit c820fbff9f added support for iSCSI
disk as backing for <disk device='lun'>. We would not use it for a disk
type="volume" with direct access mode which basically maps to direct
iSCSI usage. Fix it by adding the storage source type accessor that
resolves the volume type.
Commit 36025c552 tried to improve error reporting for <disk type="lun">
but reused the code in LXC which doesn't care about the actual disk
type. The error messages would then contain a bogous hint that the
config for the 'lun' device is invalid which might not be the case.
Re-do the relevant portion of the commit with the original message.
For disks sources described by a libvirt volume we don't need to do a
complicated check since virStorageTranslateDiskSourcePool already
correctly determines the actual disk type.
Replace the checks using a new accessor that does not open-code the
whole logic.
In 7884d089d2 I've started to refactor qemu_monitor_json.c.
Thing is, it's current structure is nothing like the rest of our
code. The @ret variable is rewritten all the time, if()-s are
nested instead of using goto and so on.

Use vshCommandOptScaledInt instead of vshCommandOptULongLong so that
values with suffixes can be passed when bytes are being passed along.
Values for the iops parameters still need to be given in the absolute
form as they are not bytes but numbers.

remove only implicit keyboards like PS2 or XEN.

Fron c3bd0019c0 on instead of creating the following path for
cgroups:
/sys/fs/cgroupX/$name.libvirt-$driver
we generate rather more verbose one:
/sys/fs/cgroupX/$driver-$id-$name.libvirt-$driver
where $name is optional and included iff contains allowed chars.
See original commit for more reasoning. Now, problem with the
original commit is that we are unable to start any LXC domain
after it. Because when starting LXC container, the CGroup layout
is created by our lxc_controller process and then detected and
validated by libvirtd. The validation is done by trying to match
detected layout against all the possible patterns for cgroup
paths that we've ever had. And the commit in question forgot to
update this part of the code.

Add the data structure and infrastructure to support an initialization
vector (IV) secrets. The IV secret generation will need to have access
to the domain private master key, so let's make sure the prepare disk
and hostdev functions can accept that now.
Anywhere that needs to make a decision over which secret type to use
in order to fill in or use the IV secret has a switch added.

Rather than need to call qemuDomainSecretDestroy after any call to
qemuProcessLaunch, let's do the destroy in qemuProcessLaunch since
that's where command line is eventually generated and processed. Once
it's generated, we can clear out the secrets.

Commit id '40d8e2ba3' added the function to qemuProcessStart because
in order to set up some secrets in the future we will need the master
key. However, since the previous patch split the master key creation
into two parts (create just the key and create the file), we can now
call qemuDomainSecretPrepare from qemuProcessPrepareDomain since the
file is not necessary.

A recent review of related changes noted that we should split the creation
(or generation) of the master key into the qemuProcessPrepareDomain and leave
the writing of the master key for qemuProcessPrepareHost.
Made the adjustment and modified some comments to functions that have
changed calling parameters, but didn't change the intro doc.

From a review after push, add the "_TYPE" into the name.

This removes the opencoded payload freeing in the client, to use
the shared virNetMessageClearPayload call. Two changes:
- ClearPayload sets nfds=0, which fixes a potential crash if
an error path called virNetMessageFree/Clear on the message
after fds was free'd
- We drop the inner loop VIR_FORCE_CLOSE... this may mean fds are
kept open a little bit longer if the call is blocking but in
practice I don't think it will have any effect
I've noticed this while trying to compile libvirt on my arm box.

Problem is, @timestap is defined as time_t which is 32 bits long,
and we are typecasting it to long long which is 64bits long.
Solution is to make @timestamp type of long long. At the same
time, we can make @conn_time in _virNetServerClient struct long
long too. There is no need for it to be type of time_t.

In this function, @id is defined as unsigned long long. When
passing this variable to virJSONValueObjectGetNumberUlong(),
well address of this variable, it's typecasted to ull*. There
is no need for that. It's a same story with @nrequests_max.

Adding new *.replies files for qemucapabilitiestest or updating the

Currently all qemu driver tests are statically linked to qemu driver
library, which makes it impossible to mock any API from the library.
This patch creates a shared qemu driver library which can be used
instead of the static one.
NB we can't use libvirt_driver_qemu.so directly since it is linked with
-module and it is supposed to be dlopened.

Bhyve supports ACPI shutdown by issuing SIGTERM signal to a bhyve
process.
Add the bhyveDomainShutdown() function and virBhyveProcessShutdown()
helper function that just sends SIGTERM to VM's bhyve process. If
a guest supports ACPI shutdown then process will be terminated and
this event will be noticed by the bhyve monitor code that will handle
setting proper status and clean up VM's resources by calling
virBhyveProcessStop().
