Issue description
When trying to create a Compute Cloud VM or a Managed Service for Kubernetes node group, you get the The limit on maximum number of cores has exceeded message.
Solution
This error occurs when the number of vCPUs for VMs in your cloud exceeds the quota. Request a quota increase using this form.
To create and use new Compute Cloud VMs or Managed Service for Kubernetes nodes, you might also need to increase other quotas, such as the following:
- Total HDD capacity
- Total SSD capacity
- Total disk snapshot size
- Number of disks
- Total VM RAM
- Number of VM instances
Check out your current usage of these quotas.
If the issue persists
If the above actions did not help, create a support ticket. Provide the following information in your ticket:
- ID for the failed operation of creating a new VM or Managed Service for Kubernetes node group.
- Text of the error message you get when trying to create new objects.
