Vadium,
After installing XS62ESP1028 via CLI (no reboot on hosts yet) and
building an Centos65 instance w/o 'Dynamic Scalable' option checked, it
showed right in XenCenter. I installed the new tools from (XS62ESP1028)
and still good. I created a template from this instance. Deployed said
template, and the memory is still good in XenCenter.
I tested on a Windows VM and it is the same with the new tools,
however, as this particular tenant bypasses the virtual router, I have
to reboot twice and reset networking as the new XenTools reset the
networking stack.

Todd,
Can you try Linux template with same dynamic scale option on the same
pool? I wonder if there is a problem with Windows or any guest OS.

Vadim.

That makes sense. I will see if I can replicate the issue in a lab. But
given the holiday weekend, might not be until next week

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).

I have 3 other pools (1 XS6.2sp1 and 2x xs65sp1) I have no issue with
these.
Based on the Design doc, what i was experiencing is by design. Ok I
will turn it off.
But now my question is, why on 4.3 I didn't have this issue but after
installing 4.3.0.2 it changed.
Was 4.3 broken or is 4.3.0.2? Will upgrading to CCP 4.5.1 will be
better?
If this is truely by design, I will not be able to use dynamic scalable
for my windows instances

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.

Latest as of XS62ESP1027. I know XS62ESP1028 comes with new XenTools.

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?

Ok. After rebooting the instance still no change after disabling
globally. I modified all my templates to remove 'Dynamic Scalable',
then I have to
shutdown every instance and unselect 'Dynamic Scalable', then restart
for
it to be correct.
This may need to be looked at closer for a Windows/XenDesktop(XenApp)
environment as MS SQL will consume all the RAM windows sees.
My other question is why CCP 4.3 (which is certified for Citrix Ready
for
IaaS for XD) didn't have this issue until I upgraded to 4.3.0.2 in
July.
This feature was released in 4.2.....
Thanks for all the help.

Just funny that on CCP 4.3 it wasn't an issue and only after upgrading
to
4.3.0.2 and a host reboot did it change my instances.
This issue is that the instance below is a SQL server. As Windows see
32GB, it shows the used RAM in windows as 31.6GB. The Server only has
8GB.
That is what really is the issue. Causing slowness for my users.
I have set 'enable.dynamic.scale.vm' to false and restarted
cloudstack-management. I will reboot an instance that is out of prod
and
let you know the results.

Hello Todd,
If I understood you correctly, you wonder why you have static max as 4x
of the offering, isn't it? This article should answer your question:

Look chapter for XenServer changes. As it is stated there: static max =
f_min (4 * service_offering) / memory_overprovisioning_of_cluster

Just wondering if anyone has seen similar. I already have a case open.
But seeing if the forum has an answer?
Issue, Upgraded to CCP 4.3.0.2 back in July. Afterwards everything was
great. Hosts rebooted two weeks ago. Any instance built with a template
with Dynamic Scalable set to yes, shows in XenCenter as min/max memory
as
what system offering is but has a Static Max of 4x the RAM.
Screen shot of instance built from template with Dynamic Scalable = yes
