ec63000a62 xenconfig: support vif bandwidth in xm and xl parser and formatter
Both xm and xl config have long supported specifying vif rate
limiting, e.g.

vif = [ 'mac=00:16:3E:74:3d:76,bridge=br0,rate=10MB/s' ]

Add support for mapping rate to and from <bandwidth> in the xenconfig
parser and formatter. rate is mapped to the required 'average' attribute
of the <outbound> element, e.g.

  <interface type='bridge'>
    ...
    <bandwidth>
      <outbound average='10240'/>
    </bandwidth>
  </interface>

Also add a unit test to check the conversion logic.

1dd34bbb4b xenconfig: support vif bandwidth in sexpr parser and formatter
The xen sexpr config format has long supported specifying vif rate
limiting, e.g.

  (device
    (vif
      (mac '00:16:3e:1b:b1:47')
      (rate '10240KB/s')
      ...
    )
  )

Add support for mapping rate to and from <bandwidth> in the xenconfig
sexpr parser and formatter. rate is mapped to the required 'average'
attribute of the <outbound> element, e.g.

  <interface type='bridge'>
    ...
    <bandwidth>
      <outbound average='10240'/>
    </bandwidth>
  </interface>

Also add unit tests to check the conversion logic.

This patch benefits both the old xen driver and the libxl driver.
Both drivers gain support for vif bandwidth when converting to/from
domXML and xen-sxpr. In addition, the old xen driver will now be
able to handle vif 'rate' setting when communicating with xend.

f87668b70e qemu: Fix NBD migration with default listenAddress
My commit 674afcb09e moved computing the
default listen address from qemuMigrationPrepareAny to
qemuMigrationPrepareIncoming. However, I didn't notice listenAddress was
later passed to qemuMigrationStartNBDServer. Thus, it would be called
with the original value of listenAddress (NULL).

Let's add the updated listen address to qemuProcessIncomingDef and use
it when starting NBD servers.

7140807917 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.

6343018fac 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.

f46d137e33 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.

  error : volStorageBackendRBDRefreshVolInfo:289 :
    failed to open the RBD image 'vol-893': Connection timed out

Ignore the error and continue to refresh the rest of the pool's

Just recently, qemu forbade specifying format for sourceless

If there's no file to open, why specify its format. Anyway, I
