How to fix Start up Virtual Machine Error

Question

Here is the error message that I am receiving

Failed to start virtual machine 'Micropay-server'. Error: Allocation failed. We do not have sufficient capacity for the requested VM size in this zone. Read more about improving likelihood of allocation success at http://aka.ms/allocation-guidance Try one of these alternative options to improve chance of allocation success: - Alternative VM sizes for the same region and zone: Standard_D2ds_v4.

Hi Gisee,

Thank you for reaching out Q/A. The error message you're receiving "Failed to start virtual machine 'Micropay-server'. Error: Allocation failed. We do not have sufficient capacity for the requested VM size in this zone." means that Azure doesn’t currently have enough free capacity in the specific zone and region you’re trying to deploy in, for that particular VM size.

This issue is not related to your configuration, but rather a capacity shortage in the underlying Azure infrastructure. This can happen, especially with large or specialized VM sizes, or during peak times.

Could you please follow below steps.

• If you’re using availability zones, try selecting another zone within the same region. It’s possible that a different zone has available capacity for the VM size you need.
• Resize a VM or add a VM to an existing availability set must be tried at the original cluster that hosts the existing availability set. The requested VM size is supported by the cluster, but the cluster may not currently have sufficient capacity.
• If the VM can be part of a different availability set, create a VM in a different availability set (in the same region). This new VM can then be added to the same virtual network.

Hope this helps! Please let me know if you have any queries.
