c517a6a369 cputest: Print correct feature in virCPUUpdateLive test
If the actual result does not match our expectation, the tests would
not correctly show the difference if a CPU feature is disabled in the
expected result and the actual result does not mention it at all. The
test could complain about an unrelated CPU feature or it could even
crash in case the actual result contains no more features to go through.

fd885a06a0 cpu: Use virDomainCapsCPUModelsPtr in cpu driver APIs
All APIs which expect a list of CPU models supported by hypervisors were
switched from char **models and int models to just accept a pointer to
virDomainCapsCPUModels object stored in domain capabilities. This avoids
the need to transform virDomainCapsCPUModelsPtr into a NULL-terminated
list of model names and also allows the various cpu driver APIs to
access additional details (such as its usability) about each CPU model.

e9f8e1b8e6 qemu: Parse unavailable features for CPU models
query-cpu-definitions QMP command returns a list of unavailable features

6885b51e5f qemu: Add TLS support for Veritas HyperScale (VxHS)
Alter qemu command line generation in order to possibly add TLS for
a suitably configured domain.

Sample TLS args generated by libvirt -

    -object tls-creds-x509,id=objvirtio-disk0_tls0,dir=/etc/pki/qemu,\
    endpoint=client,verify-peer=yes \
    -drive file.driver=vxhs,file.tls-creds=objvirtio-disk0_tls0,\
    file.vdisk-id=eb90327c-8302-4725-9e1b-4e85ed4dc251,\
    file.server.type=tcp,file.server.host=192.168.0.1,\
    file.server.port=9999,format=raw,if=none,\
    id=drive-virtio-disk0,cache=none \
    -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,\
    id=virtio-disk0

Update the qemuxml2argvtest with a couple of examples. One for a
simple case and the other a bit more complex where multiple VxHS disks
are added where at least one uses a VxHS that doesn't require TLS
credentials and thus sets the domain disk source attribute "tls = 'no'".

Update the hotplug to be able to handle processing the tlsAlias whether
it's to add the TLS object when hotplugging a disk or to remove the TLS
object when hot unplugging a disk.  The hot plug/unplug code is largely
generic, but the addition code does make the VXHS specific checks only
because it needs to grab the correct config directory and generate the
object as the command line would do.

  </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.

4fd179f518 cpu_conf: Drop updateCPU from virCPUDefFormat
In the past we updated host-model CPUs with host CPU data by adding a
model and features, but keeping the host-model mode. And since the CPU
model is not normally formatted for host-model CPU defs, we had to pass
the updateCPU flag to the formatting code to be able to properly output
updated host-model CPUs. Libvirt doesn't do this anymore, host-model
CPUs are turned into custom mode CPUs once updated with host CPU data
and thus there's no reason for keeping the hacks inside CPU XML
formatters.

eae746b2d7 Stop linking tests/commandhelper to libvirt code
The commandhelper binary is a helper for commandtest that
validates what file handles were inherited. For this to
work reliably we must not have any libraries that leak
file descriptors into commandhelper. Unfortunately some
versions of gnutls will intentionally open file handles
at library load time via a constructor function.

We previously hacked around this in

  commit 4cbc15d037
  Author: Martin Kletzander <mkletzan@redhat.com>
  Date:   Fri May 2 09:55:52 2014 +0200

    tests: don't fail with newer gnutls

    gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards
    compatible when it comes to chrooted binaries [1].  Linking
    commandhelper with gnutls then leaves these two FDs open and
    commandtest fails thanks to that.  This patch does not link
    commandhelper with libvirt.la, but rather only the utilities making
    the test pass.

    Based on suggestion from Daniel [2].

    [1] http://lists.gnutls.org/pipermail/gnutls-help/2014-April/003429.html
    [2] https://www.redhat.com/archives/libvir-list/2014-April/msg01119.html

That fix relied on fact that while libvirt.so linked with
gnutls, libvirt_util.la did not link to it.  With the
introduction of the util/vircrypto.c file that assumption
is no longer valid. We must not link to libvirt_util.la
at all - only gnulib and libc can (hopefully) be relied
on not to open random file descriptors in constructors.

8708ca01c0 nodedev: add switchdev to NIC capabilities
Adding functionality to libvirt that will allow querying the interface
for the availability of switchdev Offloading NIC capabilities.

The switchdev mode was introduced in kernel 4.8, the iproute2-devlink
command to retrieve the switchdev NIC feature with command example:

    devlink dev eswitch show pci/0000:03:00.0

This feature is needed for Openstack so we can do a scheduling decision
if the NIC is in Hardware Offload (switchdev) or regular SR-IOV (legacy) mode.
And select the appropriate hypervisors with the requested capability see [1].

8703813aae qemu: Implement usernet address
https://bugzilla.redhat.com/show_bug.cgi?id=1075520

Apart from generic checks, we need to constrain netmask/prefix
length a bit. Thing is, with current implementation QEMU needs to
be able to 'assign' some IP addresses to the virtual network. For
instance, the default gateway is at x.x.x.2, dns is at x.x.x.3,
the default DHCP range is x.x.x.15-x.x.x.30. Since we don't
expose these settings yet, it's safer to require shorter prefix
to have room for the defaults.

4775ca27e9 docs: Remove unnecessary <auth> example for iscsi disk type='volume'
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>

    <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/...

3358bfb286 qemu: Add QEMU 2.10 x86_64 the generated capabilities
For reference, these were generated by updating a local qemu git
repository to the latest upstream, making sure the latest dependencies
were met via "dnf builddep qemu" from my sufficiently privileged root
account, checking out the v2.10.0 tag, and building in order to generate
an "x86_64-softmmu/qemu-system-x86_64" image.

Then using a clean libvirt tree updated to master and built, the image
was then provided as input:

    tests/qemucapsprobe /path/to/x86_64-softmmu/qemu-system-x86_64 > \
       tests/qemucapabilitiesdata/caps_2.10.0.x86_64.replies

With the .replies file in place and the DO_TEST line added and build,
then running the following commands:

    touch tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml
    VIR_TEST_REGENERATE_OUTPUT=1 ./tests/qemucapabilitiestest

to generate tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml and both

If the "/#" is missing from the provided iSCSI path, then we need

During post parse, for any iSCSI disk or hostdev, scan the source
path looking for the presence of '/', if found, then we can assume
the LUN is provided.  If not found, alter the input XML to add the
"/0".  This will cause the generated XML to have the generated
value when the domain config is saved after post parse.

be6a415e51 qemu: set bind mode for chardev while parsing XML
Currently while parsing domain XML we clear the UNIX path if it matches
one of the auto-generated paths by libvirt.  After that when the guest
is started new path is generated but the mode is also changed to "bind".

In the real-world use-case the mode should not change, it only happens
if a user provides a mode='connect' and path that matches one of the
auto-generated path or not provides a path at all.

Before *reconnect* feature was introduced there was no issue, but with
the new feature we need to make sure that it's used only with "connect"
mode, therefore we need to move the mode change into parsing in order
to have a proper error reported by validation code.

3401e208ab qemu: Don't mangle the storage format for type='dir'
Our backing probing code handles directory file types properly in
virStorageFileGetMetadataRecurse(), by that I mean it leaves them
alone.  However its caller, the virStorageFileGetMetadata() resets the
type to raw before probing, without even checking the type.  We need
to special-case TYPE_DIR in order to achieve desired results.

Also, in order to properly test this, we need to stop resetting format
of volumes in tests for TYPE_DIR (probably the reason why we didn't
catch that and why the test data didn't need to be modified).

21bfd1e9b9 conf: error out for multiple source elements while parsing chardev
Currently we accept and correctly parse this chardev XML:

  ...
  <channel type='tcp'>
    <source mode='connect'/>
    <source mode='bind' host='localhost'/>
    <source service='4567'/>
    <target type='virtio' name='test'/>
  </channel>
  ...

The parsed formatted XML is:

  ...
  <channel type='tcp'>
    <source mode='connect' host='localhost' service='4567'/>
    <target type='virtio' name='test'/>
  </channel>
  ...

That behavior is super wrong and should not be allowed.  If you notice
the current parse takes the first found attribute and uses that value,
so for example from the "<source mode='bind' host='localhost'/>" only
the "host" attribute is used.  It works the same way for all possible
attributes that we are able to parse for source element.

This patch enforces providing only one source element for all character
devices, only for UDP type we allow to provide two source elements
since you can specify both modes.

corresponding to the test XML is converted to a libxl_domain_config

back to json using libxl_domain_config_to_json(). The two json
docs are then compared.

Using libxl to convert the json template to a libxl_domain_config

05583fcb37 qemu: command: rework adding of default cpu model
Certain XML features that aren't in the <cpu> block map to -cpu
flags on the qemu cli. If one of these is specified but the user
didn't explicitly pass an XML <cpu> model, we need to format a

The current code handles this by sprinkling this default cpu handling
among all the different flag string formatting. Instead, switch it
to do this just once.

This alters some test output slightly: the previous code would
write the default -cpu in some cases when no flags were actually
added, so the output was redundant.

f536b0dd73 tests: deterministichash: Make hash tables arch-independent
It turns out that our implementation of the hashing function is

may have different results. Work this around by mocking virHashCodeGen
to something which does not use bit operations instead of just setting a
deterministic seed.

cc6d43bb49 qemu: command: align disk serial check to schema
Disk serial schema has extra '.+' allowed characters in comparison
with check in code. Looks like there is no reason for that as qemu
allows any character AFAIK for serial. This discrepancy is originated
in commit id '85d15b51' where the ability to add serial was added.

Alter the disk-serial test to add a disk with all the possible
characters listed as the serial value.

0175dc6ea0 qemu: block: Refactor node name detection code
Remove the complex and unreliable code which inferred the node name
hierarchy only from data returned by 'query-named-block-nodes'. It turns
out that query-blockstats contain the full hierarchy of nodes as
perceived by qemu so the inference code is not necessary.

In query blockstats, the 'parent' object corresponds to the storage
behind a storage volume and 'backing' corresponds to the lower level of
backing chain. Since all have node names this data can be really easily
used to detect node names.

In addition to the code refactoring the one remaining test case needed

e5a0579996 qemu: Enable NUMA node tag in pci-root for PPC64
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.

045515d369 qemu: Use PHBs to fill holes in PCI bus numbering
PCI bus has to be numbered sequentially, and no index can be
missing, so libvirt will fill in the blanks automatically for
the user.

Up until now, it has done so using either pci-bridge, for machine
types based on legacy PCI, or pcie-root-port, for machine types
based on PCI Express. Neither choice is good for pSeries guests,
where PHBs (pci-root) should be used instead.

dacd160d74 Avoid hidden cgroup mount points
Currently the scan of the /proc/mounts file used to find cgroup mount
points doesn't take into account that mount points may hidden by other
mount points. For, example in certain Kubernetes environments the
/proc/mounts contains the following lines:

  cgroup /sys/fs/cgroup/net_prio,net_cls cgroup ...
  tmpfs /sys/fs/cgroup tmpfs ...
  cgroup /sys/fs/cgroup/net_cls,net_prio cgroup ...

In this particular environment the first mount point is hidden by the
second one. The correct mount point is the third one, but libvirt will
never process it because it only checks the first mount point for each
controller (net_cls in this case). So libvirt will try to use the first
mount point, which doesn't actually exist, and the complete detection
process will fail.

To avoid that issue this patch changes the virCgroupDetectMountsFromFile
function so that when there are duplicates it takes the information from
the last line in /proc/mounts. This requires removing the previous
explicit condition to skip duplicates, and adding code to free the
memory used by the processing of duplicated lines.

Some qemu arch/machine types have built in platform devices that
are always implicitly available. For platform serial devices, the

Apparently though since -chardev was introduced, we can use -chardev
in these cases, like this:

  -serial chardev:foo

Since -chardev enables all sorts of modern features, use this method
for platform devices.

putting hugepages path onto qemu cmd line. Clean up the
conditions so that it's more visible next time.

992bf863fc qemu: Prefer hugepages over mem source='file'
https://bugzilla.redhat.com/show_bug.cgi?id=1214369

Consider the following XML:

  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='1'/>
    </hugepages>
    <source type='file'/>
    <access mode='shared'/>
  </memoryBacking>

  <numa>
    <cell id='0' cpus='0-3' memory='512000' unit='KiB'/>
    <cell id='1' cpus='4-7' memory='512000' unit='KiB'/>
  </numa>

The following cmd line is generated:

  -object
  memory-backend-file,id=ram-node0,mem-path=/var/lib/libvirt/qemu/ram,
  share=yes,size=524288000 -numa node,nodeid=0,cpus=0-3,memdev=ram-node0
  -object
  memory-backend-file,id=ram-node1,mem-path=/var/lib/libvirt/qemu/ram,
  share=yes,size=524288000 -numa node,nodeid=1,cpus=4-7,memdev=ram-node1

This is obviously wrong as for node 1 hugepages should have been
used. The hugepages configuration is more specific than <source
type='file'/>.

Historically, we've always supported memAccess for domains backed

and stopped allowing such configuration. Fix it.
