      conf: Add/Allow parsing the encryption in the disk source · 37537a7c
      由 John Ferlan 提交于 
      Since the virStorageEncryptionPtr encryption; is a member of
 _virStorageSource it really should be allowed to be a subelement
of the disk <source> for various disk formats:

   Source{File|Dir|Block|Volume}
   SourceProtocol{RBD|ISCSI|NBD|Gluster|Simple|HTTP}

NB: Simple includes sheepdog, ftp, ftps, tftp

That way we can set up to allow the <encryption> element to be
formatted within the disk source, but we still need to be wary
from whence the element was read - see keep track and when it
comes to format the data, ensure it's written in the correct place.

Modify the qemuxml2argvtest to add a parse failure when there is an
<encryption> as a child of <disk> *and* an <encryption> as a child
of <source>.

The virschematest will read the new test files and validate from a
RNG viewpoint things are fine.

      conf: Add/Allow parsing the auth in the disk source · 8002d3cb
      由 John Ferlan 提交于 
      Since the virStorageAuthDefPtr auth; is a member of _virStorageSource
it really should be allowed to be a subelement of the disk <source>
for the RBD and iSCSI prototcols. That way we can set up to allow
the <auth> element to be formatted within the disk source.

Since we've allowed the <auth> to be a child of <disk>, we'll need
to keep track of how it was read so that when writing out we'll know
whether to format as child of <disk> or <source>. For the argv2xml
parsing, let's format under <source> as a preference. Do not allow
<auth> to be both a child of <disk> and <source>.

Modify the qemuxml2argvtest to add a parse failure when there is an
<auth> as a child of <disk> *and* an <auth> as a child of <source>.

Add tests to validate that if the <auth> was found in <source>, then
the resulting xml2xml and xml2arg works just fine.  The two new .args
file are exact copies of the non "-source" version of the file.

The virschematest will read the new test files and validate from a
RNG viewpoint things are fine

Update the virstoragefile, virstoragetest, and args2xml file to show
the "preference" to place <auth> as a child of <source>.

      qemu: Support multiqueue virtio-blk · abca72fa
      由 Lin Ma 提交于 
      qemu 2.7.0 introduces multiqueue virtio-blk(commit 2f27059).
This patch introduces a new attribute "queues". An example of
the XML:

<disk type='file' device='disk'>
  <driver name='qemu' type='qcow2' queues='4'/>

The corresponding QEMU command line:

-device virtio-blk-pci,scsi=off,num-queues=4,id=virtio-disk0

      util: Add TLS attributes to virStorageSource · f1705485
      由 Ashish Mittal 提交于 
      Add an optional virTristateBool haveTLS to virStorageSource to
manage whether a storage source will be using TLS.

Sample XML for a VxHS disk:

<disk type='network' device='disk'>
  <driver name='qemu' type='raw' cache='none'/>
  <source protocol='vxhs' name='eb90327c-8302-4725-9e1b-4e85ed4dc251' tls='yes'>
    <host name='192.168.0.1' port='9999'/>
  </source>
  <target dev='vda' bus='virtio'/>
</disk>

Additionally add a tlsFromConfig boolean to control whether the TLS
setting was due to domain configuration or qemu.conf global setting
in order to decide whether to Format the haveTLS setting for either
a live or saved domain configuration file.

Update the qemuxml2xmltest in order to add a test to show the proper
parsing.

Also update the docs to describe the tls attribute.

      docs: Remove unnecessary <auth> example for iscsi disk type='volume' · 4775ca27
      由 John Ferlan 提交于 
      Alter the example to remove the <auth> from:

  <disk type='volume' device='disk'>
    <driver name='qemu' type='raw'/>
    <source pool='iscsi-pool' volume='unit:0:0:1' mode='host'/>
    <auth username='myuser'>
      <secret type='iscsi' usage='libvirtiscsi'/>
    </auth>
    <target dev='vdb' bus='virtio'/>
  </disk>

and

  <disk type='volume' device='disk'>
    <driver name='qemu' type='raw'/>
    <source pool='iscsi-pool' volume='unit:0:0:2' mode='direct'/>
    <auth username='myuser'>
      <secret type='iscsi' usage='libvirtiscsi'/>
    </auth>
    <target dev='vdc' bus='virtio'/>
  </disk>

The reality is, it's not even used. For a <source pool> the authdef
from the storage source pool will supercede whatever is in the <disk>
definition during virStorageTranslateDiskSourcePool processing. In fact,
if the pool doesn't have/need authentication, then the authdef would
be removed anyway as the storage pool would be handling things.

The "proof" for this is in the adjustment to the test to add an
<auth> for a disk. The resulting .args file won't add what normally
would be added "myname:encodedpassword@" prior to the hostname in
the IQN (e.g. iscsi://myname:encodedpassword@iscsi.example.org:3260/...

      qemu: Enable NUMA node tag in pci-root for PPC64 · e5a05799
      由 Shivaprasad G Bhat 提交于 
      This patch addresses the same aspects on PPC the bug 1103314 addressed
on x86.

PCI expander bus creates multiple primary PCI busses, where each of these
busses can be assigned a specific NUMA affinity, which, on x86 is
advertised through ACPI on a per-bus basis.

For SPAPR, a PHB's NUMA affinities are assigned on a per-PHB basis, and
there is no mechanism for advertising NUMA affinities to a guest on a
per-bus basis. So, even if qemu-ppc manages to get some sort of multi-bus
topology working using PXB, there is no way to expose the affinities
of these busses to the guest. It can only be exposed on a per-PHB/per-domain
basis.

So patch enables NUMA node tag in pci-root controller on PPC.

The way to set the NUMA node is through the numa_node option of
spapr-pci-host-bridge device. However for the implicit PHB, the only way
to set the numa_node is from the -global option. The -global option applies
to all the PHBs unless explicitly specified with the option on the
respective PHB of CLI. The default PHB has the emulated devices only, so
the patch prevents setting the NUMA node for the default PHB.
