Need help with service offerings

[SviridoffA]

Hi Everyone!! I have two clusters in one Zone (one zone wide storage), I have created 2 types of compute offering? and separate it with host tags. I want to be able start instances on both clusters by changing this service offering for instance. But then I stop instance and trying to change offering, I can't find offering for anothe clusters in proposed (scale instance button). In documentation I have found Strict Host Tags parameters - https://docs.cloudstack.apache.org/en/4.20.1.0/adminguide/host_and_storage_tags.html#strict-host-tags . But I cant find this parameters in global settings. Can anyone give me some advice on how to solve this problem?

@SviridoffA What is the version of Cloudstack you are using? Looks like global setting is available from 4.20 onwards #9017

I'm using ACS 4.19.3.. But I'm not sure I even need this setting. These are the only settings I found in docs that might be related to my main problem. Main problem - I can't see compute offering from another cluster when trying vm scaling((.

Yes, the global setting you referred to in the initial query is not related to your issue.

You are not seeing the service offerings with different tag as I see that the UI is only listing the service offerings available for that particular VM (which would be service offerings with current tag or no tag at all). However, you should be able to change the service offering to one with different tag using the scaleVirtualMachine API https://cloudstack.apache.org/api/apidocs-4.19/apis/scaleVirtualMachine.html

Thanks for the link. I have tested this and it works great with the API. It’s especially convenient with CloudMonkey, but it can be difficult for regular users. Is this really a UI limitation, and is there no way to avoid this in the UI? Maybe some database change?

This is happening because listserviceofferings API being invoked in the context of Virtual machine when we click on "Scale Instance". Below is the API invoked. This will result in listing the service offerings that has compatible host tags or no tags at all

Maybe you can submit a feature or improvement request to include service offerings with different tags if needed.

Just a FYI, A feature request in the past was submitted to include service offerings with no tags here #6359

@prashanthr2 Thank you for your time and the detailed explanation. I have created a feature request.
