Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
Based on the issue description, looks like you are trying to create a VM in East US, but you are getting an error that the 'Following SKUs have failed for Capacity Restrictions: Standard_D4s_v3' is currently not available in location eastus.
Below are few suggestions you can try to solve your deployment issue:
The VM size Standard_D4s_v3 might be unavailable in East US due to current capacity limits. You can use az vm list-sizes --location eastus --output table
to list all the available VM sizes in the region. Select a different VM size that is available in the East US 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 East US location. Not all VM sizes may be available in all zones of a given region.
If you have any further queries, please do let us know.
