This fixed the previous commit (-s => -s ip).

Since on dual-homed clusters one always needs to add '-s' to the
gnt-node add command, make this appear in the output of 'gnt-node' (when
run without arguments).

This was reported by Henning Sprang in issue #14. Also add a missing word

By default xen tries to save running virtual machines at system shutdown and
restore them at reboot. Make sure we suggest to disable this feature in the
installation manual.

The install manual was missing python-pyparsing and python-simplejson from the
apt-get install list. Adding them.

Thanks to Henning Sprang for spotting this issue.

Right now an assembly error produces an exception but not a log message. This
is bad because the exception suggests looking at the log, but the log itself
has a lot of errors which are not really a problem and only some which really
is. In order to make it clear where in the log the problem occurred we log a
message too, before raising the exception.

This makes the tests much more reliably because it avoids race conditions.
It also helps to speed them up a lot.

We want to prevent sending too many 'None' children to a device.
However, the test as it is today is wrong, as we want to test the
situation after adding a new child, and not before. This patch fixes
this by testing greater-or-equal instead of just greater.

The code assumes all lines have at least two elements which are
whitespace separated - i.e. it does not deal with empty lines or comment
lines with no spaces. This patch fixes this.

Also, the patch replaces the blank between IP and the canonical name
with a tab (restoring previous behaviour).

This is a critical file. Breaking it would be very bad. Thus, if the system
crashes before the data is synched to the disk, it should have the complete
file afterwards.

In order to make the replace secondary action to be done via the same
opcode parameters for both remote_raid1 and drbd, we must allow the
LUReplaceDisks to change replace_disks_all for drbd with non-empty
remote_node into replace_disks_sec.

This fixes gnt-node evacuate and also allows gnt-instace replace-disks
to have the same syntax for both remote_raid1 and drbd (when replacing
the secondary).

The --nodes option in gnt-backup really accepts only one node at a time.
Change it to --node, for added clarity and consistency with a similar
option in gnt-cluster. This patch also updates the relevant man page.

  - update the NEWS file by changing format (format taken by looking at
    /usr/sharea/doc/*/NEWS.gz) and adding more information on changes
