    stubdom: disable building pv-grub
    
    The stubdom based pv-grub is using a very outdated version of grub
    (0.97) and should not be used any longer. Mainline grub has support for
    PV guests for a long time now, so that should be used as a boot loader
    of a PV domain.
    
    So disable building pv-grub per default. In case someone really wants
    to continue using it he/she can still use a pv-grub binary from an older
    Xen version or manually enable building it via:
    
      configure --enable-pv-grub
    
    [ This was already disabled in osstest by 8dee6e333622
      "make-flight: Drop pvgrub (pvgrub1) tests" -iwj ]

    tools/xenstore: set open file descriptor limit for xenstored
    
    Add a configuration item for the maximum number of open file
    descriptors xenstored should be allowed to have.
    
    The default should be "unlimited" in order not to restrict xenstored
    in the number of domains it can support, but unfortunately the kernel
    is normally limiting the maximum value via /proc/sys/fs/nr_open [1],
    [2]. So check that file to exist and if it does, limit the maximum
    value to the one specified by /proc/sys/fs/nr_open.
    
    As an aid for the admin configuring the value add a comment specifying
    the common needs of xenstored for the different domain types.

    tools/xenstore: set oom score for xenstore daemon on Linux
    
    Xenstored is absolutely mandatory for a Xen host and it can't be
    restarted, so being killed by OOM-killer in case of memory shortage is
    to be avoided.
    
    Set /proc/$pid/oom_score_adj (if available) per default to -500 (this
    translates to 50% of dom0 memory size) in order to allow xenstored to
    use large amounts of memory without being killed.
    
    The percentage of dom0 memory above which the oom killer is allowed to
    kill xenstored can be set via XENSTORED_OOM_MEM_THRESHOLD in
    xencommons.
    
    Make sure the pid file isn't a left-over from a previous run delete it
    before starting xenstored.
