      Export the hypervisor.ValidateParameters over RPC · 6217e295
      Iustin Pop authored
      The newly-added node-specific ValidateParams hypervisor method is
      exported over RPC, using the semi-standard (success, message) return
      value. Multi-node call, so that we call on both primary and secondary at
      once.

      Implement parameter removal in SplitKeyVal · fcd62d84

      This patch adds paramter removal in SplitKeyVal, by prefixing a
      value-less key with "-"; this is needed in resetting parameters back to
      cluster defaults, but care must be applied now that None can come from
      the parser.

      Fix a few rpc-related errors · 16ad1a83
      Iustin Pop authored
      This fixes:
        - whitespace change, double lines between methods
        - duplication of call_upload_file, introduced by mistake in rev 1795
          and which went undetected because of the many changes in that ref
          (only diff -b shows it clearly)

      Add two new options types for CLI usage · a8469393
      Iustin Pop authored
      For the new 2.0-style command line options, we need to parse strings of
      the type:
        ident:key=val[,...]
      and
        key=val[,...]
      
      This patch adds two new option builders for these two, which return
      (ident, {key=val,}) and {key=val,} for the above two formats. It also
      handles specially constructs of type “key” (val is set to True) and
      “no_key” (val is set to False, and the ‘no_’ prefix is stripped).

      Abstract checking own address into a function · caad16e2
      Iustin Pop authored
      Currently, we check if we have a given ip address (i.e. it's alive on
      one of our interfaces) but manually calling TcpPing(source=localhost).
      This works, but having it spread all over the code makes it hard to
      change the implementation.
      
      The patch abstracts this into a separate utils.OwnIpAddress(addr)
      function. We add a rpc call for it, which we use instead of the
      (single-use of) call_node_tcp_ping. We leave node_tcp_ping in, as seems
      useful and eventually it should be removed in a separate patch.

      Convert rpc module to RpcRunner · 72737a7f
      Iustin Pop authored
      This big patch changes the call model used in internode-rpc from
      standalong function calls in the rpc module to via a RpcRunner class,
      that holds all the methods. This can be used in the future to enable
      smarter processing in the RPC layer itself (some quick examples are not
      setting the DiskID from cmdlib code, but only once in each rpc call,
      etc.).
      
      There are a few RPC calls that are made outside of the LU code, and
      these calls are left as staticmethods, so they can be used without a
      class instance (which requires a ConfigWriter instance).

      Cleanup in cmdlib for standalone function calls · b9bddb6b
      Iustin Pop authored
      This patch is a cleanup of the standalone functions in cmdlib. Many of
      them too as argument a ConfigWriter instance, but some also took other
      parameters from the lu (e.g. proc), and in the future, if we want to
      also pass the RpcRunner, we would have to add yet another parameter.
      
      One option is to make all these methods of top-level LogicalUnit class.
      I took another approach, and made (almost) all these functions take as
      first parameter the lu instance. It's like methods, just not declared
      under LogicalUnit.

      Move the hypervisor attribute to the instances · e69d05fd
      Iustin Pop authored
      This (big) patch moves the hypervisor type from the cluster to the
      instance level; the cluster attribute remains as the default hypervisor,
      and will be renamed accordingly in a next patch. The cluster also gains
      the ‘enable_hypervisors’ attribute, and instances can be created with
      any of the enabled ones (no provision yet for changing that attribute).
      
      The many many changes in the rpc/backend layer are due to the fact that
      all backend code read the hypervisor from the local copy of the config,
      and now we have to send it (either in the instance object, or as a
      separate parameter) for each function.
      
      The node list by default will list the node free/total memory for the
      default hypervisor, a new flag to it should exist to select another
      hypervisor. Instance list has a new field, hypervisor, that shows the
      instance hypervisor. Cluster verify runs for all enabled hypervisor
      types.
      
      The new FIXMEs are related to IAllocator, since now the node
      total/free/used memory counts are wrong (we can't reliably compute the
      free memory).
