      net-dhcp-leases: Implement the public APIs · 03e0e79e
      Nehal J Wani 提交于
      Introduce 3 new APIs, virNetworkGetDHCPLeases, virNetworkGetDHCPLeasesForMAC

      * virNetworkGetDHCPLeases: returns the dhcp leases information for a given
           virtual network.
      
        For DHCPv4, the information returned:
        - Network Interface Name
        - Expiry Time
        - MAC address
        - IAID (NULL)
        - IPv4 address (with type and prefix)
        - Hostname (can be NULL)
        - Client ID (can be NULL)
      
        For DHCPv6, the information returned:
        - Network Interface Name
        - Expiry Time
        - MAC address
        - IAID (can be NULL, only in rare cases)
        - IPv6 address (with type and prefix)
        - Hostname (can be NULL)
        - Client DUID
      
        Note: @mac, @iaid, @ipaddr, @clientid are in ASCII form, not raw bytes.
        Note: @expirytime can 0, in case the lease is for infinite time.
      
      * virNetworkGetDHCPLeasesForMAC: returns the dhcp leases information for a
           given virtual network and specified MAC Address.
      
      * virNetworkDHCPLeaseFree: allows the upper layer application to free the
           network interface object conveniently.
      
      There is no support for flags, so user is expected to pass 0 for

      virNumaGetPageInfo: Take huge pages into account · 3499eedd

      On the Linux kernel, if huge pages are allocated the size they cut off
      from memory is accounted under the 'MemUsed' in the meminfo file.

      qemu: parse -device virtio-balloon · ef016226
      Laine Stump 提交于
      There are no options to parse here other than the name of the device,
      and all three possible device names have the same prefix
      ("virtio-balloon" with "-ccw", "-pci", or "-device" appended), so the
      code is fairly simple. It has been implemented such that it will be
      easier to add handling for other -device entries that aren't otherwise
      recognized - just add another "else if (STRPREFIX(opts, ....)" clause.
      
      qemuParseCommandLineString() previously would always add a <memballoon
      model='virtio'/> to every result (the comments erroneously say that it
      is adding a <memballoon model='none'/>) This has been changed to add
      model='none', and 84 test case xml's updated accordingly (so that
      qemuxml2argvtest won't fail).
      
      Now that the memballoon device is properly parsed, we can safely add a
      test for properly ignoring -nodefconfig and -nodefaults. Rather than
      adding an entire new test case for this (and memballoon), we just
      randomly pick the clock-utc test and modify it slightly to fulfill the
      purpose.

      "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.

      security: Rename virSecurityManagerSetImageLabel to *Disk* · c8e42205
      Peter Krempa 提交于
      I'm going to add functions that will deal with individual image files
      rather than whole disks. Rename the security function to make room for
      the new one.
