      Move to data-based hvparam checks instead of code · 205ab586
      Iustin Pop authored
      Currently the hypervisor parameters are checked using hard-coded snippets in
      each hypervisor. However, most parameter checks fall into three cases:
        - file check
        - directory check
        - string value in a set
      
      And the remaining ones are checked using simple functions.
      
      This patch moves to a declarative-style for these parameter checks; in
      hv_base we add the necessary infrastructure for these checks, and the
      above common cases.
      
      This translates into complete removal of the Check/Verify functions for
      the Xen hypervisors, and a drastic reduction for the KVM one (which has
      inter-parameter dependencies and thus can't use a simple table).

      Move more hypervisor strings into constants · 835528af
      Iustin Pop authored
      This patch adds constants for the mouse and boot order strings; while
      there are still some issues remaining, we're trying to cleanup hardcoded
      strings from the hypervisors.
      
      Since the formatting of frozensets is currently wrong, we also add an
      utility function for this and change all the error messages to use it.

      watcher: try to restart the master if down · 7dfb83c2
      Iustin Pop authored
      Bugs in either our code or in associated libraries can bring the master daemon
      down, and this (due to the 2.0 architecture) stops all work on the cluster.
      
      Since the watcher already does periodic checks on the cluster, we modify
      it to try to start the master automatically in case of failures to
      connect. This will be tried only once per cycle.
      
      Also, in this case, we modify the code so that the watcher status file
      is not updated - its timestamp will reflect thus the time of last
      successful connection to the master.
      
      Side note: the except errors.ConfigurationError part could be cleaned
      up, since in 2.0 we don't usually get that directly, and if we do it's
      an error and we shouldn't touch the file anyway; but that is not a rc5
      change.

      IAllocator: export total disk size for instances · 88ae4f85
      Iustin Pop authored
      This patch adds for current instance a ‘disk_space_total’ key, similar
      to the key for the new instance in case of new allocations.

      Add -H/-B startup parameters to gnt-instance · d04aaa2f
      Iustin Pop authored
      This patch modifies the start instance script, opcode and logical unit
      to support temporary startup parameters.
      
      Different from 1.2, where only the kernel arguments were supporting
      changes (and thus xen-pvm specific), this version supports changing all
      hypervisor and backend parameters (with appropriate checks).
      
      This is much more flexible, and allows for example:
        - start with different, temporary kernel
        - start with different memory size
      
      Note: in later versions, this should be extended to cover disk
      parameters as well (e.g. start with drbd without flushes, start with
      drbd in async mode, etc.).

      call_instance_start: add optional hv/be parameters · 0eca8e0c
      Iustin Pop authored
      This patch modifies the rpc.call_instance_start - the master side - to
      take optional hv/be parameters. The noded side is unchanged and
      oblivious to the change.
      
      This will allow implementation of single-user capability and such on
      startup (temporary, as opposed to permanent).
