The CPU contains the updated microcode for CVE-2017-5715.
The *-guest.xml and *-json.xml CPU definitions use Skylake-Client CPU
model rather than Broadwell. This is similar to Xeon-E5-2650-v4 and it
is caused by our CPU model selection code when no model matches the CPU
signature (family + model). We'd need to maintain a complete list of CPU
signatures for our CPU models to fix this.

Libvirt 3.7.0 and earlier libvirt reported a migration job as completed
immediately after QEMU finished sending migration data at which point
migration was not really complete yet. Commit v3.7.0-29-g3f2d6d829e
fixed this, but caused a regression in reporting statistics for
completed jobs which started reporting the job as still running. This
happened because the completed job statistics including the job status
are copied from the running job before we finally mark it as completed.
Let's make sure QEMU_DOMAIN_JOB_STATUS_COMPLETED is always set in the
completed job info even when the job has not finished yet.

the interface name is returned (e.g. "vnet0", usually available

When returning a string that needs escaping there are two
scenarios that can happen. Firstly, user already started the

In the future, this function is going to be called from
vshReadlineParse() to provide parsed input for completer
callbacks. The idea is to allow the callbacks to provide more
specific data. For instance, for the following input:
virsh # domifaddr --domain fedora --interface <TAB><TAB>
the --interface completer callback is going to be called. Now, it
is more user friendly if the completer offers only those
interfaces found in 'fedora' domain. But in order to do that it
needs to be able to retrieve partially parsed result.

Alter the volume logic to use the hash tables instead of forward
linked lists. There are three hash tables to allow for fast lookup
by name, target.path, and key.
Modify the virStoragePoolObjAddVol to place the object in all 3
tables if possible using self locking RWLock on the volumes object.
Conversely when removing the volume, it's a removal of the object
from the various hash tables.
Implement functions to handle remote ForEach and Search Volume
type helpers. These are used by the disk backend in order to
facilitate adding a primary, extended, or logical partition.
Implement the various VolDefFindBy* helpers as simple (and fast)
hash lookups. The NumOfVolumes, GetNames, and ListExport helpers
are all implemented using standard for each hash table calls.
Prepare for hash table volume lists by creating the object infrastructure
for a Volume Object and Volume Object List
The _virStorageVolObj will contain just a pointer to the "current"
(and live) volume definition.
The _virStorageVolObjList will contain three hash tables, one for
each of the lookup options allowed for a volume.
Alter the logic such that we only add the volume to the pool once
we've filled in all the information and cause failure to go to a
common error: label. Patches to place the @vol into a few hash tables
will soon "require" that at least the keys (name, target.path, and key)
be populated with valid data.
For a disk backend, the deleteVol code will clear all the
volumes in the pool and perform a pool refresh, thus the
storageVolDeleteInternal should not use access @voldef
after deleteVol succeeds.
