Hello Mario D
Welcome to Microsoft Q&A Platform, thanks for posting your query here.
Based on the issue description, looks like you are trying to create a VM on West US 2, but you are getting an error that the requested VM size 'Standard_B2ms' is not available in that location. According to the error message, the SKU is failing due to capacity restrictions.
Although you mentioned that there should be no limitation for "Standard_B2ms" in West US 2, it's possible that the availability of specific VM sizes can change over time due to various factors such as capacity restrictions, maintenance, or updates in Azure data centers.
Check the Azure status page to see if there are any known issues in the West US 2 region that could be affecting capacity.
Below are few suggestions you can try to solve your deployment issue:
-Select a different VM size that is available in the "westus2" location.
-If the specific VM size is critical for your requirements, you can choose a different Azure region or location where the desired VM size is available.
-If your deployment requires zone-specific resources, consider deploying to a different zone within the "westus2" location. Not all VM sizes may be available in all zones of a given region.
Hope this helps.
