      interface: clean up virInterfaceDefDevFormat · 0b33d7c9
      Laine Stump 提交于
      This modifies the formatting function of virInterface to be a proper
      mirror of the parse function, including the addition of a
      "parentIfType" arg so that we can decide whether or not it is
      appropriate to emit the elements that are only in toplevel interfaces,
      as well as the <link> element (which isn't allowed for bridge
      interfaces).
      
      Since the restructuring of the code necessarily changes the order of
      some of the elements, some test case data had to be updated.

      interface: clean up virInterfaceDefParseXML · 3aa81973
      Laine Stump 提交于
      the switch cases for the 4 different interface types had repetitive
      code which has now been pulled out as common. While touching those
      lines, some extra usage of "!= NULL" etc has been eliminated to make
      things more compact and inline with current coding practices.
      
      NB: parentIfType == VIR_INTERFACE_TYPE_LAST means that this is a
      toplevel interface (not a subordinate of a bridge or bond). Only
      toplevel interfaces can have a start mode, mtu, or IP address element.

      interface: move parsing of bridge attributes into appropriate function · 7edc46ac
      Laine Stump 提交于
      For some reason the bridge stp mode and delay were put directly into
      the "bridge" case of the switch in virInterfaceDefParseXML(), although
      they are inside the <bridge> element, and so should be parsed in the
      function created for that purpose - virInterfaceBridgeDefFormat().

      interface: report link state for bonds and vlans too · 69db5f92
      Laine Stump 提交于
      The interface state for bonds and vlans does seem to reflect the state
      of the underlying physical devices, at least in some cases, so it
      makes sense to allow reporting it (netcf now does).
      
      The link state/speed for bridge devices is meaningless though, so we
      don't even look for it.

      blockjob: use stable disk string in job event · 1bfe73a1
      Eric Blake 提交于
      When the block job event was first added, it was for block pull,
      where the active layer of the disk remains the same name.  It was
      also in a day where we only cared about local files, and so we
      always had a canonical absolute file name.  But two things have
      changed since then: we now have network disks, where determining
      a single absolute string does not really make sense; and we have
      two-phase jobs (copy and active commit) where the name of the
      active layer changes between the first event (ready, on the old
      name) and second (complete, on the pivoted name).
      
      Adam Litke reported that having an unstable string between events
      makes life harder for clients.  Furthermore, all of our API that
      operate on a particular disk of a domain accept multiple strings:
      not only the absolute name of the active layer, but also the
      destination device name (such as 'vda').  As this latter name is
      stable, even for network sources, it serves as a better string
      to supply in block job events.
      
      But backwards-compatibility demands that we should not change the
      name handed to users unless they explicitly request it.  Therefore,
      this patch adds a new event, BLOCK_JOB_2 (alas, I couldn't think of
      any nicer name - but at least Migrate2 and Migrate3 are precedent
      for a number suffix).  We must double up on emitting both old-style
      and new-style events according to what clients have registered for
      (see also how IOError and IOErrorReason emits double events, but
      there the difference was a larger struct rather than changed
      meaning of one of the struct members).
      
      Unfortunately, adding a new event isn't something that can easily
      be broken into pieces, so the commit is rather large.

      Eric Blake 提交于
      Commit 7c6fc394 introduced a regression in the XML produced for older

      depending on output-only data for something that is only going to
      be triggered for a transient guest; but John Ferlan reported that
      the automated testsuite was such a client.  It's better to be safe
      than sorry by guaranteeing back-compat cruft.  Note that later

      virNodeDevCapPCIDevParseXML: Initialize numa_node variable · bab45585
      Michal Privoznik 提交于
      With one of my recent patches (1c702778) libvirt's capable of
      reporting NUMA node locality for PCI devices. The node ID is
      stored in pci_dev.numa_node variable. However, since zero is
      valid NUMA node ID, the default is -1 as it is in kernel too.
      So, if the PCI device is not tied to any specific NUMA node, the
      default is then NOT printed into XML. Therefore, when parsing
      node device XML, the <node/> element is optional. But currently,
      if it's not there, we must set sane default, otherwise after
      parsing in the memory representation doesn't match the XML. We
      are already doing this in other place: udevProcessPCI().

      node_device: Expose link state & speed · 0311ef3d

      While exposing the info under <interface/> in previous patch works, it
      may work only in cases where interface is configured on the host.
      However, orchestrating application may want to know the link state and

      virInterface: Expose link state & speed · 3db89662
      Michal Privoznik 提交于
      Currently it is not possible to determine the speed of an interface
      and whether a link is actually detected from the API. Orchestrating
      platforms want to be able to determine when the link has failed and
      where multiple speeds may be available which one the interface is
      actually connected at. This commit introduces an extension to our
      interface XML (without implementation to interface driver backends):
      
        <interface type='ethernet' name='eth0'>
          <start mode='none'/>
          <mac address='aa:bb:cc:dd:ee:ff'/>

          <mtu size='1492'/>
          ...
        </interface>
      
      Where @speed is negotiated link speed in Mbits per second, and state
      is the current NIC state (can be one of the following:  "unknown",
      "notpresent", "down", "lowerlayerdown","testing", "dormant", "up").

      conf: alter disk mirror xml output · 7c6fc394
      Eric Blake 提交于
      Now that we track a disk mirror as a virStorageSource, we might
      as well update the XML to theoretically allow any type of
      mirroring destination (not just a local file).  A later patch
      will also be reusing <mirror> to track the block commit of the
      top layer of a chain, which is another case where libvirt needs
      to update the backing chain after the job is finally pivoted,
      and since backing chains can have network backing files as the
      destination to commit into, it makes more sense to display that
      in the XML.
      
      This patch changes output-only XML; it was already documented
      that <mirror> does not affect a domain definition at this point
      (because qemu doesn't provide persistent bitmaps yet).  Any
      application that was starting a block copy job with older libvirt
      and then relying on the domain XML to determine if it was
      complete will no longer be able to access the file= and format=
      attributes of mirror that were previously used.  However, this is
      not going to be a problem in practice: the only time a block copy
      job works is on a transient domain, and any app that is managing
      a transient domain probably already does enough of its own
      bookkeeping to know which file it is mirroring into without
      having to re-read it from the libvirt XML.  The one thing that
      was likely to be used in a mirroring job was the ready=
      attribute, which is unchanged.  Meanwhile, I made sure the schema
      and parser still accept the old format, even if we no longer
      output it, so that upgrading from an older version of libvirt is
      seamless.

      nodedev: Export NUMA node locality for PCI devices · 1c702778
      Michal Privoznik 提交于
      A PCI device can be associated with a specific NUMA node. Later, when
      a guest is pinned to one NUMA node the PCI device can be assigned on
      different NUMA node. This makes DMA transfers travel across nodes and
      thus results in suboptimal performance. We should expose the NUMA node
      locality for PCI devices so management applications can make better
      decisions.

      In "src/conf/domain_conf.h" there are many enumerations (enum)

      it's better to use a typedef for variable types, function types and

      over the source code. This time, most of the files changed in this
      commit are related to part of one file: "src/conf/domain_conf.h".

      qemu: fix RTC_CHANGE event for <clock offset='variable' basis='utc'/> · b62d67da
      Laine Stump 提交于
      commit e31b5cf3 attempted to fix libvirt's
      VIR_DOMAIN_EVENT_ID_RTC_CHANGE, which is documentated to always
      provide the new offset of the domain's real time clock from UTC. The
      problem was that, in the case that qemu is provided with an "-rtc
      base=x" where x is an absolute time (rather than "utc" or
      "localtime"), the offset sent by qemu's RTC_CHANGE event is *not* the
      new offset from UTC, but rather is the sum of all changes to the
      domain's RTC since it was started with base=x.
      
      So, despite what was said in commit e31b5cf3, if we assume that
      the original value stored in "adjustment" was the offset from UTC at
      the time the domain was started, we can always determine the current
      offset from UTC by simply adding the most recent (i.e. current) offset
      from qemu to that original adjustment.
      
      This patch accomplishes that by storing the initial adjustment in the
      domain's status as "adjustment0". Each time a new RTC_CHANGE event is
      received from qemu, we simply add adjustment0 to the value sent by
      qemu, store that as the new adjustment, and forward that value on to
      any event handler.
      
      This patch (*not* e31b5cf3, which should be reverted prior to
      applying this patch) fixes:
      
      https://bugzilla.redhat.com/show_bug.cgi?id=964177
      
      (for the case where basis='utc'. It does not fix basis='localtime')

      This reverts commit e31b5cf3.
      
      This commit attempted to work around a bug in the offset value
      reported by qemu's RTC_CHANGE event in the case that a variable base
      date was given on the qemu commandline. The patch mixed up the math
      involved in arriving at the corrected offset to report, and in the
      process added an unnecessary private attribute to the clock
      element. Since that element is private/internal and not used by anyone
      else, it makes sense to simplify things by removing it.

      Eric Blake 提交于
      This partially reverts commits b279e52f and ea18f8b2.
      
      It turns out our code base is full of:
      
      if ((struct.member = virBlahFromString(str)) < 0)
          goto error;
      
      Meanwhile, the C standard says it is up to the compiler whether
      an enum is signed or unsigned when all of its declared values
      happen to be positive.  In my testing (Fedora 20, gcc 4.8.2),
      the compiler picked signed, and nothing changed.  But others
      testing with gcc 4.7 got compiler warnings, because it picked
      the enum to be unsigned, but no unsigned value is less than 0.
      Even worse:
      
      if ((struct.member = virBlahFromString(str)) <= 0)
          goto error;
      
      is silently compiled without warning, but incorrectly treats -1
      from a bad parse as a large positive number with no warning; and
      without the compiler's help to find these instances, it is a
      nightmare to maintain correctly.  We could force signed enums
      with a dummy negative declaration in each enum, or cast the
      result of virBlahFromString back to int after assigning to an
      enum value, or use a temporary int for collecting results from
      virBlahFromString, but those actions are all uglier than what we
      were trying to cure by directly using enum types for struct
      values in the first place.  It's better off to just live with int
      members, and use 'switch ((virFoo) struct.member)' where we want
      the compiler to help, than to track down all the conversions from
      string to enum and ensure they don't suffer from type problems.

      used as more of a union of multiple enums in storage volume
      code (so it has to remain an int), and virStorageSourcePoolDef
      refers to pooltype whose enum is declared in src/conf, but where
