vCPUs are not available for the host size family on the dedicated host.

Question

Encountering an error indicating that vCPUs are currently unavailable across all host families within the specified host group.

I've attempted multiple combinations of regions and sizes, including Central US, East US 2, West India, and various sizes like DADSv5, DCsv2, and DCsv3, but the desired vCPUs are not accessible.

Is there any misconfiguration here, or could this issue be related to Azure?

also, how can I create a dedicated host in azure?

Hello, @Bharat K !

What do I do if VM vCPUs aren't available in my region?

There are two components to this: available quota for your subscription and SKU availability for the region you are interested in.

You can submit a request for a quota increase if vCPU resources are available in that region. If not, you can look for a region that has more vCPUs available for the VM SKUs you are interested in using the following command in Azure CLI:

az vm list-skus --location centralus --size Standard_D --all --output table

Looking at the VM sizes you are currently interested in and the regions you've listed, I would recommend looking at South Central US which has DCsv2 and DCsv3.
