      conf: add features to volume target XML · 31d42506
      Ján Tomko 提交于
      Add <features> and <compat> elements to volume target XML.
      
      <compat> is a string which for qcow2 represents the QEMU version
      it should be compatible with. Valid values are 0.10 and 1.1.
      1.1 is implicit if the <features> element is present, otherwise
      qemu-img default is used. 0.10 can be specified to explicitly
      create older images after the qemu-img default changes.
      
      <features> contains optional features, so far
      <lazy_refcounts/> is available, which enables caching of reference
      counters, improving performance for snapshots.

      conf: add 'sharePolicy' attribute to graphics element for vnc · 2a58d076
      Guannan Ren 提交于
       -vnc :5900,share=allow-exclusive
      allows clients to ask for exclusive access which is
      implemented by dropping other connections Connecting
      multiple clients in parallel requires all clients asking
      for a shared session (vncviewer: -shared switch)
      
       -vnc :5900,share=force-shared
      disables exclusive client access.  Useful for shared
      desktop sessions, where you don't want someone forgetting
      specify -shared disconnect everybody else.
      
       -vnc :5900,share=ignore
      completely ignores the shared flag and allows everybody
      connect unconditionally

      qemu: Support discard for disk · a7c4202c
      Osier Yang 提交于
      QEMU introduced "discard" option for drive since commit a9384aff53,
      
      <...>
      @var{discard} is one of "ignore" (or "off") or "unmap" (or "on") and
      controls whether @dfn{discard} (also known as @dfn{trim} or @dfn{unmap})
      requests are ignored or passed to the filesystem.  Some machine types
      may not support discard requests.
      </...>
      
      This patch exposes the support in libvirt.
      
      QEMU supported "discard" for "-drive" since v1.5.0-rc0:
      
      % git tag --contains a9384aff53
      contains
      v1.5.0-rc0
      v1.5.0-rc1
      
      So this only detects the capability bit using virQEMUCapsProbeQMPCommandLine.

      Support for static routes on a virtual bridge · ccff335f
      Gene Czarcinski 提交于
      network: static route support for <network>
      
      This patch adds the <route> subelement of <network> to define a static
      route.  the address and prefix (or netmask) attribute identify the
      destination network, and the gateway attribute specifies the next hop
      address (which must be directly reachable from the containing
      <network>) which is to receive the packets destined for
      "address/(prefix|netmask)".
      
      These attributes are translated into an "ip route add" command that is
      executed when the network is started. The command used is of the
      following form:
      
        ip route add <address>/<prefix> via <gateway> \
                     dev <virbr-bridge> proto static metric <metric>
      
      Tests are done to validate that the input data are correct.  For
      example, for a static route ip definition, the address must be a
      network address and not a host address.  Additional checks are added
      to ensure that the specified gateway is directly reachable via this
      network (i.e. that the gateway IP address is in the same subnet as one
      of the IP's defined for the network).
      
      prefix='0' is supported for both family='ipv4' address='0.0.0.0'
      netmask='0.0.0.0' or prefix='0', and for family='ipv6' address='::',
      prefix=0', although care should be taken to not override a desired
      system default route.
      
      Anytime an attempt is made to define a static route which *exactly*
      duplicates an existing static route (for example, address=::,
      prefix=0, metric=1), the following error message will be sent to
      syslog:
      
          RTNETLINK answers: File exists
      
      This can be overridden by decreasing the metric value for the route
      that should be preferred, or increasing the metric for the route that
      shouldn't be preferred (and is thus in place only in anticipation that
      the preferred route may be removed in the future).  Caution should be
      used when manipulating route metrics, especially for a default route.
      
      Note: The use of the command-line interface should be replaced by
      direct use of libnl so that error conditions can be handled better.  But,
      that is being left as an exercise for another day.

      Currently the fdstream function hardcodes the location

      util: move virFile* functions from virutil.c to virfile.c · bfe7721d
      Laine Stump 提交于
      These all existed before virfile.c was created, and for some reason
      weren't moved.
      
      This is mostly straightfoward, although the syntax rule prohibiting
      write() had to be changed to have an exception for virfile.c instead
      of virutil.c.
      
      This movement pointed out that there is a function called
      virBuildPath(), and another almost identical function called
      virFileBuildPath(). They really should be a single function, which
      I'll take care of as soon as I figure out what the arglist should look
      like.

      virstring: Introduce VIR_STRDUP and VIR_STRNDUP · c3abb5c4
      Michal Privoznik 提交于
      The code adaptation is not done right now, but in subsequent patches.
      Hence I am not implementing syntax-check rule as it would break
      compilation. Developers are strongly advised to use these new macros.
      They are similar to VIR_ALLOC() logic: VIR_STRDUP(dst, src) returns zero
      on success, -1 otherwise. In case you don't want to report OOM error,
      use the _QUIET variant of a macro.

      util: new virCommandSetMax(MemLock|Processes|Files) · 776d49f4
      Laine Stump 提交于
      This patch adds two sets of functions:
      
      1) lower level virProcessSet*() functions that will immediately set
      the RLIMIT_MEMLOCK. RLIMIT_NPROC, or RLIMIT_NOFILE of either the
      current process (using setrlimit()) or any other process (using
      prlimit()). "current process" is indicated by passing a 0 for pid.
      
      2) functions for virCommand* that will setup a virCommand object to
      set those limits at a later time just after it has forked a new
      process, but before it execs the new program.
      
      configure.ac has prlimit and setrlimit added to the list of functions
      to check for, and the low level functions log an "unsupported" error)
      on platforms that don't support those functions.

      pci: keep a stubDriver in each virPCIDevice · be64199e

      driver to bind/unbind for managed devices.
      
      The existing Detach and Attach functions' signatures haven't been
      changed (they still accept a stub driver name in the arg list), but if
      the arg list has NULL for stub driver and one is available in the
      device's object, that will be used. (we may later deprecate and remove
      the arg from those functions).

      qemu: Fix setting of memory tunables · fa006c4f
      Peter Krempa 提交于
      Refactoring done in 19c6ad9a didn't
      correctly take into account the order cgroup limit modification needs to
      be done in. This resulted into errors when decreasing the limits.
      
      The operations need to take place in this order:
      
      decrease hard limit
      change swap hard limit
      
      or
      
      change swap hard limit
      increase hard limit
      
      This patch also fixes the check if the hard_limit is less than
      swap_hard_limit to print better error messages. For this purpose I
      introduced a helper function virCompareLimitUlong to compare limit
      values where value of 0 is equal to unlimited. Additionally the check is
      now applied also when the user does not provide all of the tunables
      through the API and in that case the currently set values are used.

      virNetworkLoadState and a few friends that will help us to load status
