Question

I have been trying to create a virtual machine within my host pool but I keep getting validation failed but it doesn't say why.

Hi Scott,

Based on the error message you are seeing, you need to increase your Quota for Standard DASv5 Family vCPUs in West US 3 Region. You may do this by navigating to link below:

https://portal.azure.com/#view/Microsoft_Azure_Capacity/QuotaMenuBlade/~/myQuotas

In the search box, please enter standard dasv5, set the Region filter to West US 3. Next click pencil icon on the right to fill out Quota request, as shown below:

For this current request, decide how many vCPUs total of this VM size you will need for West US 3 and enter it in the box. You need to consider how many vCPUs each VM instance will use and how many VMs you plan to deploy.

For example, if you plan on having two session hosts using Standard_D2as_v5, then each one would need 2 vCPUs for a total of 4 vCPUs needed:

Additionally, you may need to increase your Total Regional vCPUs Quota for West US 3. To do this repeat above process, except enter "total regional vcpus" in the search box. This quota is the total number of vCPUs allowed, regardless of instance family, for the region (West US 3 in this case).

Please click Accept Answer and upvote if the above was helpful.

Thanks.
