RE: Compute and Disk Offerings of CloudStack

[Pranav Saxena <pr...@citrix.com>]

Hey Zaw ,

Below are the answers to your questions  -


1)     assign CPU and Memory in Compute Offering for VMs?-   Stop the VM , assign the compute offering to the VM and start the VM again

2)     Is there any formula or an assignment of CoreCPUs, CPU speed and Memory regarding compute offerings - These are probably based on what the hypervisor can support and the there are limits imposed based on them which is handled by the backend Java code.

3)     the min and max number of CPU and Memory for compute offering - CloudStack doesn’t impose any limits as such as far as I know. If you have that much hardware and your hypervisor supports that then you should be fine to deploy your instance with whatever value you specify else Cloudstack would throw an exception of “Insufficient Capacity “ .

4)     assign Disk size in Disk offering - This you can do while deploying the VM through the instance wizard . There are standard disk sizes available or you also have the flexibility of choosing a custom disk offering . Also , you could create your own disk offering under the Service offerings tab and deploy your VM using that.

5)     min and max number of Disk size for disk offerings - Again , I would say I don’t think so that CloudStack specifies any limit for disk offerings . If you have the hardware available , you should be good to go .

Someone in the community who has been working on the hypervisor specific module for cloudstack ( resource base) can better answer your queries.

Thanks,
Pranav

Hi Pranav,

I’d like to know about one thing that how to assign CPU and Memory in Compute Offering for VMs? Is there any formula or an assignment of CoreCPUs, CPU speed and Memory regarding compute offerings? May I know the min and max number of CPU and Memory for compute offering? Moreover, How to assign Disk size in Disk offering? May I know the min and max number of Disk size for disk offerings? Can we assign any number whatever we want it?

And I’m looking forward to your reply email.

Kind regards,
Zaw
