My first attempts to create spot VMs (using the web UI) are universally failing at the final validation step with:
{"code":"InvalidTemplateDeployment","message":"The template deployment failed with error: 'The resource with id: '/subscriptions/.../resourceGroups/builder_group/providers/Microsoft.Compute/virtualMachines/builder' failed validation with message: 'The requested size for resource '/subscriptions/.../resourceGroups/builder_group/providers/Microsoft.Compute/virtualMachines/builder' is currently not available in location 'eastus' zones '' for subscription '...'. Please try another size or deploy to a different location or zones. See https://aka.ms/azureskunotavailable for details.'.'."}
This applies in every zone I have tried. My quota listings show 350 vCPUs for nearly all VM types (including all I am trying), and 350 "spot CPUs" (these don't seem to be broken out by VM type). This validation failure does not occur using otherwise identical settings but with a non-spot instance.
What else do I need to check? What other quotas or subscription changes might I need to request from support to be able to create spot instances?
