I'm trying to set up a new Azure virtual machine with specifications of 16GB of RAM and 4 vCPUs. The specific plans I'm considering are b4ms, f4as, or d4as, which are already in use by other VMs in the same resource group and subnet. However, when I try to select the size in the basics section, I keep getting options that only have 2 vCPUs and less RAM than I need. I don't want to change the resource group or subnet, and I have plenty of quota available. What options do I have to resolve this issue? I've thought about changing regions, but that would change the subnet too, and cloning a similar VM would help preserve the subnet and NSG rules. Any guidance would be appreciated!

When selecting the SKU for your VM, make sure to search directly for the specifications you need, like b4ms. If it's not available, it should either be grayed out with an explanation or not show up at all. Check that you're selecting the right region as SKU availability can vary. If it says something like 'size not available in region for this subscription', that indicates a limitation on your current setup.
Sounds like a quota mismatch. If the quota shows 48 out of 250 allowed regional CPUs, try checking your subscription limits. Sometimes, specific sizes have stricter quota rules that don't align with the overall CPU count.
I got the message for b4ms too – it said it’s not available in that region for my subscription. For the other sizes, it mentioned a quota issue, but I see my quotas say I can use more CPUs. What gives?
