Subject Re: Dynamic Scalable Template issue
Date Fri, 04 Sep 2015 18:19:14 GMT
I am afraid this issue has nothing to do with Cloudstack. If VM "sees" 
maximum memory size available instead of effective -- this is problem of 
hypervisor and/or guest utilities. Do you have guest utilities that come 
with XenServer version or older in your template?

Vadim.
