Re: Dynamic Scalable Template issue
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.

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).

Re: Dynamic Scalable Template issue
Posted by Todd Pigram <to...@toddpigram.com>.
Is this fixed in 4.5.1 as the issue is not listed in the release notes under CS-27425/CS-21217?
As a FYI, on the one VM the new tools worked but not on any others. I had to set ‘enable.dynamic.scale.vm’ to false, restart management service. Then I have to shutdown the instance. then start, to get the right memory. A reboot doesn’t fix it.

RE: Dynamic Scalable Template issue
Posted by Somesh Naidu <So...@citrix.com>.
A similar issue is listed in CCP 4.5 release notes – look for “CS-27425/CS-21217”.

Subject: Re: Dynamic Scalable Template issue
Well its seems to be a XS Tools issue. I am waiting to here back from support on the ‘Official’ word, but with the new tools installed and the Dynamic Scalable option set, I am currently running like I was before the upgrade to CCP 4.3.0.2.
At this point it is closed.
Thanks for the help.

Have you tried to do the following manual tests on the cluster where you have problem:
1. Dynamically scalable with CentOS ?
2. Dynamically scalable with Windows ?
What do they show as available RAM?

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.

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

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.

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

This feature was released in 4.2.....

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.

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.

Vadium,
Yes to both with the new tools from XS62ESP1028. Both Windows and CentOS have ‘Dynamic Scalable’ Option selected and in XenCenter they show the correct RAM.

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.

Re: Dynamic Scalable Template issue
Posted by Vadim Kimlaychuk <va...@kickcloud.net>.
Todd,
Have you tried to do the following manual tests on the cluster
where you have problem:
1. Dynamically scalable with CentOS ?
2. Dynamically scalable with Windows ?
What do they show as available RAM?

2. Dynamically scalable with Windows ?
