      Add support for forcing a private network namespace for LXC guests · 10a8b1f9
      Daniel P. Berrange 提交于
      If no <interface> elements are included in an LXC guest XML
      description, then the LXC guest will just see the host's
      network interfaces. It is desirable to be able to hide the
      host interfaces, without having to define any guest interfaces.
      
      This patch introduces a new feature flag <privnet/> to allow
      forcing of a private network namespace for LXC. In the future
      I also anticipate that we will add <privuser/> to force a
      private user ID namespace.
      
      * src/conf/domain_conf.c, src/conf/domain_conf.h: Add support
        for <privnet/> feature. Auto-set <privnet> if any <interface>

      qemu: Support numad · 0f8e7ae3
      Osier Yang 提交于
      numad is an user-level daemon that monitors NUMA topology and
      processes resource consumption to facilitate good NUMA resource
      alignment of applications/virtual machines to improve performance
      and minimize cost of remote memory latencies. It provides a
      pre-placement advisory interface, so significant processes can
      be pre-bound to nodes with sufficient available resources.
      
      More details: http://fedoraproject.org/wiki/Features/numad
      
      "numad -w ncpus:memory_amount" is the advisory interface numad
      provides currently.
      
      This patch add the support by introducing a new XML attribute
      for <vcpu>. e.g.
      
        <vcpu placement="auto">4</vcpu>
        <vcpu placement="static" cpuset="1-10^6">4</vcpu>
      
      The returned advisory nodeset from numad will be printed
      in domain's dumped XML. e.g.
        <vcpu placement="auto" cpuset="1-10^6">4</vcpu>
      
      If placement is "auto", the number of vcpus and the current
      memory amount specified in domain XML will be used for numad
      command line (numad uses MB for memory amount):
        numad -w $num_of_vcpus:$current_memory_amount / 1024
      
      The advisory nodeset returned from numad will be used to set
      domain process CPU affinity then. (e.g. qemuProcessInitCpuAffinity).
      
      If the user specifies both CPU affinity policy (e.g.
      (<vcpu cpuset="1-10,^7,^8">4</vcpu>) and placement == "auto"
      the specified CPU affinity will be overridden.
      
      Only QEMU/KVM drivers support it now.
      
      See docs update in patch for more details.

      qemu: fix segfault when detaching non-existent network device · 19c7980e
      Guannan Ren 提交于
      In qemuDomainDetachNetDevice, detach was being used before it had been
      validated. If no matching device was found, this resulted in a
      dereference of a NULL pointer.
      
      This behavior was a regression introduced in commit
      cf90342b, so it has not been a part of
      any official libvirt release.

      qemu: Fix (managed)save and snapshots with host mode CPU · 041109af
      Jiri Denemark 提交于
      When host-model and host-passthrouh CPU modes were introduced, qemu
      driver was properly modify to update guest CPU definition during
      migration so that we use the right CPU at the destination. However,
      similar treatment is needed for (managed)save and snapshots since they
      need to save the exact CPU so that a domain can be properly restored.
      To avoid repetition of such situation, all places that need live XML
      share the code which generates it.
      
      As a side effect, this patch fixes error reporting from
      qemuDomainSnapshotWriteMetadata().

      util: standardize return from functions calling virNetlinkCommand · 0208face
      Laine Stump 提交于
      There are several functions that call virNetlinkCommand, and they all
      follow a common pattern, with three exit labels: err_exit (or
      cleanup), malformed_resp, and buffer_too_small. All three of these
      labels do their own cleanup and have their own return. However, the
      malformed_resp label usually frees the same items as the
      cleanup/err_exit label, and the buffer_too_small label just doesn't
      free recvbuf (because it's known to always be NULL at the time we goto
      buffer_too_small.
      
      In order to simplify and standardize the code, I've made the following
      changes to all of these functions:
      
      1) err_exit is replaced with the more libvirt-ish "cleanup", which
         makes sense because in all cases this code is also executed in the
         case of success, so labelling it err_exit may be confusing.
      
      2) rc is initialized to -1, and set to 0 just before the cleanup
         label. Any code that currently sets rc = -1 is made to instead goto
         cleanup.
      
      3) malformed_resp and buffer_too_small just log their error and goto
         cleanup. This gives us a single return path, and a single place to
         free up resources.
      
      4) In one instance, rather then logging an error immediately, a char*
         msg was pointed to an error string, then goto cleanup (and cleanup
         would log an error if msg != NULL). It takes no more lines of code
         to just log the message as we encounter it.
      
      This patch should have 0 functional effects.

      util: eliminate device object leaks related to virDomain*Remove*() · f985773d
      Laine Stump 提交于
      There are several functions in domain_conf.c that remove a device
      object from the domain's list of that object type, but don't free the
      object or return it to the caller to free. In many cases this isn't a
      problem because the caller already had a pointer to the object and
      frees it afterward, but in several cases the removed object was just
      left floating around with no references to it.
      
      In particular, the function qemuDomainDetachDeviceConfig() calls
      functions to locate and remove net (virDomainNetRemoveByMac), disk
      (virDomainDiskRemoveByName()), and lease (virDomainLeaseRemove())
      devices, but neither it nor its caller qemuDomainModifyDeviceConfig()
      ever obtain a pointer to the device being removed, much less free it.
      
      This patch modifies the following "remove" functions to return a
      pointer to the device object being removed from the domain device
      arrays, to give the caller the option of freeing the device object
      using that pointer if needed. In places where the object was
      previously leaked, it is now freed:
      
        virDomainDiskRemove
        virDomainDiskRemoveByName
        virDomainNetRemove

      lead to the lower level function failing (and not removing the object
      from the domain's hostdevs list), but the higher level function
      free'ing the hostdev object anyway. This would leave a stale
      hostdevdef pointer in the list, which would surely cause a problem
      eventually.
      
      This patch relocates virDomainHostdevRemove from the lower level
      functions qemuDomainDetachThisHostDevice and
      qemuDomainDetachHostPciDevice, to their caller
      qemuDomainDetachThisHostDevice, placing it just before the call to
      virDomainHostdevDefFree. This makes it easy to verify that either both
      operations are done, or neither.
      
      NB: The "dangling pointer" part of this problem was introduced in
      commit 13d5a6, so it is not present in libvirt versions prior to
      0.9.9. Earlier versions would return failure in certain cases even
      though the the device object was removed/deleted, but the removal and
      deletion operations would always both happen or neither.

      util: consolidate duplicated error messages in virnetlink.c · 879bcee0
      Laine Stump 提交于
      There are special stub versions of all public functions in this file
      that are compiled when either libnl isn't available or the platform
      isn't linux. Each of these functions had two almost identical message,
      differing only in the function name included in the message. Since log
      messages already contain the function name, we can just define a const
      char* with the common part of the string, and use that same string for
      all the log messages.
      
      Also, rather than doing #if defined ... #else ... #endif *inside the
      error log macro invocation*, this patch does #if defined ... just
      once, using it to decide which single string to define. This turns the
      error log in each function from 6 lines, to 1 line.

      This patch will allow OpenFlow controllers to identify which interface
      belongs to a particular VM by using the Domain UUID.

      V2 changes:
      Replaced vm-uuid with vm-id. There was a discussion in Open vSwitch
      mailinglist that we should stick with the same DB key postfixes for the
      sake of consistency (e.g iface-id, vm-id ...).

      The indentation on the final lines of the function was off by four

      missing. (There wasn't.)
