qemu: Don't bother user with libvirt-internal paths
If user defines a virtio channel with UNIX socket backend and doesn't
care about the path for the socket (e.g. qemu-agent channel), we still
generate it into the persistent XML. Moreover when then user renames
the domain, due to its persistent socket path saved into the per-domain
directory, it will not start. So let's forget about old generated paths
and also stop putting them into the persistent definition.
rbd: Do not append Ceph monitor port number 6789 if not provided
If no port number was provided for a storage pool libvirt defaults to
port 6789; however, librbd/librados already default to 6789 when no port
number is provided.
In the future Ceph will switch to a new port for the Ceph monitors since
port 6789 is already assigned to a different application by IANA.
Port 6789 is assigned to SMC-HTTPS and Ceph now has port 3300 assigned as
the 'Ceph monitor' port.
In this case it is the best solution to not hardcode any port number into
libvirt and let librados handle the connection.
Only if a user specifies a different port number we pass it down to librados,
otherwise we leave it blank.

rbd: Do not error out on a single image during pool refresh
It could happen that rbd_list() returns X names, but that while
refreshing the pool one of those RBD images is removed from Ceph
through a different route then libvirt.
We do not need to error out in such case, we can simply ignore the
volume and continue.
error : volStorageBackendRBDRefreshVolInfo:289 :
failed to open the RBD image 'vol-998': No such file or directory
It could also be that one or more Placement Groups (PGs) inside Ceph
are inactive due to a system failure.
If that happens it could be that some RBD images can not be refreshed
and a timeout will be raised by librados.

It could be that we error out while the RBD image has not been

Set it to NULL by default and only close if it is not NULL.

Revert "admin: Rename virAdmConnect to virAdmDaemon"
Commmit df8192aa introduced admin related rename and some minor
(caused by automated approach, aka sed) and some more severe isues along with
it. First reason to revert is the inconsistency with libvirt library.
Although we deal with the daemon directly rather than with a specific
hypervisor, we still do have a connection. That being said, contributors might
get under the impression that AdmDaemonNew would spawn/start a new daemon
(since it's admin API, why not...), or AdmDaemonClose would do the exact
opposite or they might expect DaemonIsAlive report overall status of the daemon
which definitely isn't the case.
The second reason to revert this patch is renaming virt-admin client. The
client tool does not necessarily have to reflect the names of the API's it's
using in his internals. An example would be 's/vshAdmConnect/vshAdmDaemon'
where noone can be certain of what the latter function really does. The former
is quite expressive about some connection magic it performs, but the latter does
not say anything, especially when vshAdmReconnect and vshAdmDisconnect were
left untouched.

Xen: support maxvcpus in xm and xl config
From: Ian Campbell <ian.campbell@citrix.com>
xend prior to 4.0 understands vcpus as maxvcpus and vcpu_avail
as a bit map of which cpus are online (default is all).
xend from 4.0 onwards understands maxvcpus as maxvcpus and
vcpus as the number which are online (from 0..N-1). The
upstream commit (68a94cf528e6 "xm: Add maxvcpus support")
claims that if maxvcpus is omitted then the old behaviour
(i.e. obeying vcpu_avail) is retained, but AFAICT it was not,
in this case vcpu==maxcpus==online cpus. This is good for us
because handling anything else would be fiddly.
This patch changes parsing of the virDomainDef maxvcpus and vcpus
entries to use the corresponding 'maxvcpus' and 'vcpus' settings
from xm and xl config. It also drops use of the old Xen 3.x
'vcpu_avail' setting.
The change also removes the maxvcpus limit of MAX_VIRT_VCPUS (since
maxvcpus is simply a count, not a bit mask), which is particularly
crucial on ARM where MAX_VIRT_CPUS == 1 (since all guests are
expected to support vcpu placement, and therefore only the boot
vcpu's info lives in the shared info page).
Existing tests adjusted accordingly, and new tests added for the
'maxvcpus' setting.
Commit id '3c7590e0a' added the flag to the rbd backend, but provided
no means via virsh to use the flag. This patch adds a '--delete-snapshots'
option to both the "undefine" and "vol-delete" commands.
For "undefine", the flag is combined with the "--remove-all-storage" flag
in order to add the appropriate flag for the virStorageVolDelete call;
whereas, for the "vol-delete" command, just the flag is sufficient since
it's only operating on one volume.

lxc_cgroup: Add check for NULL cgroup before AddTask call
Commit id '71ce4759' altered the cgroup processing with respect to the
call to virCgroupAddTask being moved out from lower layers into the calling
layers especially for qemu processing of emulator and vcpu threads. The
movement affected lxc insomuch as it is possible for a code path to
return a NULL cgroup *and* a 0 return status via virCgroupNewPartition
failure when virCgroupNewIgnoreError succeeded when virCgroupNewMachineManual
returns. Coverity pointed out that would cause virCgroupAddTask to core.
This patch will check for a NULL cgroup as well as the negative return
and just return the NULL cgroup to the caller (as it would have previously)

Utilize recently added VIR_STORAGE_POOL_CREATE_WITH_BUILD* flags in

virStoragePoolCreate API's.
This affects the 'virsh pool-create', 'virsh pool-create-as', and

doesn't need the flags, they could prove useful for someone trying to
do one command build --overwrite and start command processing or

Add flags handling to the virStoragePoolCreate and virStoragePoolCreateXML

pool create API's to also perform a pool build during creation rather than
requiring the additional buildPool step. This will allow transient pools
to be defined, built, and started.
The new flags are:
* VIR_STORAGE_POOL_CREATE_WITH_BUILD
Perform buildPool without any flags passed.
* VIR_STORAGE_POOL_CREATE_WITH_BUILD_OVERWRITE
Perform buildPool using VIR_STORAGE_POOL_BUILD_OVERWRITE flag.
* VIR_STORAGE_POOL_CREATE_WITH_BUILD_NO_OVERWRITE
Perform buildPool using VIR_STORAGE_POOL_BUILD_NO_OVERWRITE flag.
It is up to the backend to handle the processing of build flags. The
overwrite and no-overwrite flags are mutually exclusive.
