4fac5a9fd3 Use virGetLastErrorMessage to avoid Coverity message
Both instances use VIR_WARN() to print the error from a failed
virDBusGetSystemBus() call.  Rather than use the virGetLastError
and need to check for valid return err pointer, just use the
virGetLastErrorMessage.

f0187c1f27 qemu: command: unconditionally allow accel3d='no'
This matches how we handle spice gl='no' even if spice GL isn't
supported. Not too interesting in practice but I figure we should
be consistent

a391a9c5b1 qemu: domain: Don't treat unknown storage type as not having backing chain
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.

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1328003

In qemuCheckDiskConfig would now use virDomainDiskSourceIsBlockType just

82ba41108a qemu: Support <disk device='lun'> for iSCSI direct mapped volumes
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.

5e9d56f83f lxc: Fix wrong error message on disk hotplug
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.

3ec7bb354a util: Replace virDomainDiskSourceIsBlockType with a new helper
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.

fb377701f2 virCgroupValidateMachineGroup: Reflect change in CGroup struct naming
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.

bead05ea4d qemu: Introduce qemuDomainSecretIV
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.

b6238738ea rpc: use virNetMessageClearPayload in client
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

b17e610e1f virNetServerClientNewPostExecRestart: Avoid align problems

  CC       rpc/libvirt_net_rpc_server_la-virnetserverclient.lo
rpc/virnetserverclient.c: In function 'virNetServerClientNewPostExecRestart':
rpc/virnetserverclient.c:516:45: error: cast increases required alignment of target type [-Werror=cast-align]

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.
