      Separate internal node suspend APIs from public API · 4a044d02
      由 Daniel P. Berrange 提交于 
      The individual hypervisor drivers were directly referencing
APIs in virnodesuspend.c in their virDriverPtr struct. Separate
these methods, so there is always a wrapper in the hypervisor
driver. This allows the unused virConnectPtr args to be removed
from the virnodesuspend.c file. Again this will ensure that
ACL checks will only be performed on invocations that are
directly associated with public API usage.

      Separate virGetHostname() API contract from driver APIs · ead63031
      由 Daniel P. Berrange 提交于 
      Currently the virGetHostname() API has a bogus virConnectPtr
parameter. This is because virtualization drivers directly
reference this API in their virDriverPtr tables, tieing its
API design to the public virConnectGetHostname API design.

This also causes problems for access control checks since
these must only be done for invocations from the public
API, not internal invocation.

Remove the bogus virConnectPtr parameter, and make each
hypervisor driver provide a dedicated function for the
driver API impl. This will allow access control checks
to be easily inserted later.

      build: avoid useless virAsprintf · 25ae3d30
      由 Eric Blake 提交于 
      virAsprintf(&foo, "%s", bar) is wasteful compared to
foo = strdup(bar) (or eventually, VIR_STRDUP(foo, bar),
but one thing at a time...).

Noticed while reviewing Laine's attempt to clean up broken
qemu:///session.

      virutil: Move string related functions to virstring.c · 7c9a2d88
      由 Michal Privoznik 提交于 
      The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

      pci: autolearn name of stub driver, remove from arglist · e482693b
      由 Laine Stump 提交于 
      virPCIDeviceReattach and virPCIDeviceUnbindFromStub (called by
virPCIDeviceReattach) had previously required the name of the stub
driver as input. This is unnecessary, because the name of the driver
the device is currently bound to can be found by looking at the link:

  /sys/bus/pci/dddd:bb:ss.ff/driver

Instead of requiring that the name of the expected stub driver name
and only unbinding if that one name is matched, we no longer take a
driver name in the arglist for either of these
functions. virPCIDeviceUnbindFromStub just compares the name of the
currently bound driver to a list of "well known" stubs (right now
contains "pci-stub" and "vfio-pci" for qemu, and "pciback" for xen),
and only performs the unbind if it's one of those devices.

This allows virsh nodedevice-reattach to work properly across a
libvirtd restart, and fixes a couple of cases where we were
erroneously still hard-coding "pci-stub" as the drive name.

For some unknown reason, virPCIDeviceReattach had been calling
modprobe on the stub driver prior to unbinding the device. This was
problematic because we no longer know the name of the stub driver in
that function. However, it is pointless to probe for the stub driver
at that time anyway - because the device is bound to the stub driver,
we are guaranteed that it is already loaded, and so that call to
modprobe has been removed.

      xen: implement virNodeDeviceDetachFlags backend · cad14a52
      由 Laine Stump 提交于 
      This was the only hypervisor driver other than qemu that implemented
virNodeDeviceDettach. It doesn't currently support multiple pci device
assignment driver backends, but it is simple to plug in this new API,
which will make it easier for Xen people to fill it in later when they
decide to support VFIO (or whatever other) device assignment. Also it
means that management applications will have the same API available to
them for both hypervisors on any given version of libvirt.

The only acceptable value for driverName in this case is NULL, since
there is no alternate, and I'm not willing to pick a name for the
default driver used by Xen.

      virCaps: get rid of defaultConsoleTargetType callback · 482e5f15
      由 Peter Krempa 提交于 
      This patch refactors various places to allow removing of the
defaultConsoleTargetType callback from the virCaps structure.

A new console character device target type is introduced -
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was
specified in the XML. This type is at the end converted to the standard
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are
different from this default have to be processed separately in the
device post parse callback.

      virCaps: get rid of macPrefix field · 46becc18
      由 Peter Krempa 提交于 
      Use the virDomainXMLConf structure to hold this data and tweak the code
to avoid semantic change.

Without configuration the KVM mac prefix is used by default. I chose it
as it's in the privately administered segment so it should be usable for
any purposes.

      conf: Add post XML parse callbacks and prepare for cleaning of virCaps · 43b99fc4
      由 Peter Krempa 提交于 
      This patch adds instrumentation that will allow hypervisor drivers to
fill and validate domain and device definitions after parsed by the XML
parser.

With this patch, after the XML is parsed, a callback to the driver is
issued requesting to fill and validate driver specific details of the
configuration. This allows to use sensible defaults and checks on a per
driver basis at the time the XML is parsed.

Two callback pointers are stored in the new virDomainXMLConf object:
* virDomainDeviceDefPostParseCallback (devicesPostParseCallback)
  - called for a single device parsed and for every single device in a
    domain config. A virDomainDeviceDefPtr is passed along with the
    domain definition and virCaps.

* virDomainDefPostParseCallback, (domainPostParseCallback)
  - A callback that is meant to process the domain config after it's
  parsed.  A virDomainDefPtr is passed along with virCaps.

Both types of callbacks support arbitrary opaque data passed for the
callback functions.

Errors may be reported in those callbacks resulting in a XML parsing
failure.

      virCaps: conf: start splitting out irrelevat data · 27cf98e2
      由 Peter Krempa 提交于 
      The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.

This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:

1) Get rid of the stuff from virCaps

2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.

This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.
