Prasanna Santhanam commented on CLOUDSTACK-2683:
------------------------------------------------

This doesn't seem to be a problem on a XCP 1.6 host. The devcloud xcp-xapi.log 
lists the following lines:

[20130526T06:36:32.088Z|debug|devcloud|510 INET

Server_helpers.exec exception_handler: Got exception 
MEMORY_CONSTRAINT_VIOLATION: [ Memory limits must satisfy: static_min ≤ dy
namic_min ≤ dynamic_max ≤ static_max ]

The memory limits are in the required range with static_min <= dynamic_min = 
dynamic_max = static_max


Further investigating the failure.
