Comment #5 on issue 621 by [email protected]: Instance related opcodes do
not aquire network/group locks
http://code.google.com/p/ganeti/issues/detail?id=621
The following patch fixes the problem described in comment #2.
It doesn't fix the main issue. Solving it properly would require to lock
all instances, which could impact users considerably. Therefore we postpone
the problem until we refactor the locking system.

Lock group(s) when creating instances.
This is required to prevent race conditions such as removing a network
from a group and adding an instance at the same time. (See issue 621#2.)
