Subject Re: Dynamic Scalable Template issue
Date Sat, 05 Sep 2015 07:38:11 GMT
Todd,

        You may try to create VM at XenServer without CloudStack just 
using XE tool (or XenCenter). If your manually created VM with static 
max <> dynamic max will be OK, then there is a problem with Cloudstack.
