Subject Re: Dynamic Scalable Template issue
Date Sat, 05 Sep 2015 16:44:52 GMT
Todd,

         I have seeing similar problem with Xen 4.1 (not XenServer). 
Linux guests were able to see (and use) entire host resources on any 
guest VM. That was a bug of configuration. If you think about what could 
be different after CS update - it could be VM registration procedure. 
Still guest VM should not be able to see static max. Your XenCenter 
shows that effective dynamic VM memory size is 8Gb while maximium is 
32Gb. So CS configured VM guest correctly. This is problem of hypervisor 
<-> guest VM communitcation. That is why I asked you to try to register 
VM manually. I believe you will have the same result. Than means your 
server pool of XS62ESP1027 is broken. 3 other pools are not. I see no 
reason to update to 4.5.1, because I think this is not the problem of 
CS, but particularly this XenServer pool + this type of Windows guest 
(if other templates with dynamic offer are good).

Vadim.
