Tomasz Zieba commented on CLOUDSTACK-9251:
------------------------------------------
Ok, I have understood the workaround but we have implemented few features which
use the custom offering.
Custom offering works without any problems in ACS4.5.2 and that's why upgrade
to ACS 4.7.1 is for us impossible.
I think that I have found the source of the problem.
When you are creating Instance and choose custom offering, you can start
instance with custom offering without any problems.
The function validateCustomParameters gets the following data ( named as
customParameters):
{cpuNumber=2, cpuSpeed=1500, memory=2048}
BUT
when you are changing offering on stopped instance the same function get the
following data ( named as customParameters):
{0={cpuNumber=2, cpuSpeed=2000, memory=2048}}
That's why validation is wrong. The functions inside method
validateCustomParameters can't get cpu count properly and method throws
Exception.
I'm sorry but I'm not java developer but maybe you can check the reason of this
situation.
