    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.).
