      Add a node powercycle command · f5118ade
      Iustin Pop authored
      
      
      This (somewhat big) patch adds support for remotely rebooting the nodes
      via whatever support the hypervisor has for such a concept.
      
      For KVM/fake (and containers in the future) this just uses sysrq plus a
      ‘reboot’ call if the sysrq method failed. For Xen, it first tries the
      above, and then Xen-hypervisor reboot (we first try sysrq since that
      just requires opening a file handle, whereas xen reboot means launching
      an external utility).
      
      The user interface is:
      
          # gnt-node powercycle node5
          Are you sure you want to hard powercycle node node5?
          y/[n]/?: y
          Reboot scheduled in 5 seconds
      
      The node reboots hopefully after sending the reply. In case the clock is
      broken, “time.sleep(5)” might take ages (but then I suspect SSL
      negotiation wouldn't work).

      Add a luxi call for multi-job submit · 2971c913
      Iustin Pop authored
      
      
      As a workaround for the job submit timeouts that we have, this patch
      adds a new luxi call for multi-job submit; the advantage is that all the
      jobs are added in the queue and only after the workers can start
      processing them.
      
      This is definitely faster than per-job submit, where the submission of
      new jobs competes with the workers processing jobs.
      
      On a pure no-op OpDelay opcode (not on master, not on nodes), we have:
        - 100 jobs:
          - individual: submit time ~21s, processing time ~21s
          - multiple:   submit time 7-9s, processing time ~22s
        - 250 jobs:
          - individual: submit time ~56s, processing time ~57s
                        run 2:      ~54s                  ~55s
          - multiple:   submit time ~20s, processing time ~51s
                        run 2:      ~17s                  ~52s
      
      which shows that we indeed gain on the client side, and maybe even on
      the total processing time for a high number of jobs. For just 10 or so I
      expect the difference to be just noise.
      
      This will probably require increasing the timeout a little when
      submitting too many jobs - 250 jobs at ~20 seconds is close to the
      current rw timeout of 60s.

      Doc fixes for RAPI · c8e0a534
      Iustin Pop authored
      
      
      After moving the documentation from the .py files to .rst, we had some
      cleanups to do.
      
      This fixes the formatting of the comments, improves them a little, and
      removes deprecated info (DOC_URI) from the python source.

      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).
