Trying to change the default VM size on a host pool

[Bas van der Kruijssen]

Hello all,

I'm looking for a way to change the default VM size for a host pool. When I first created a hostpool I used the Standard_E2as_v4 size never realizing this size would be the default for all hosts to be added at a later date.

I haven't found a way to change this size either through the portal or with the new AzWvd* PowerShell module.

Am I missing something or is this just not possible after a hostpool is created?

@Bas van der Kruijssen  Not possible after a Host Pool is created I believe.

@SteveMiles70 Missed that note on the docs page, thanks for the link :)

I understand the importance of VM sizes to be equal for all VM's in a hostpool. However, it's still possible to change the VM size from the virtual machine blade without problems. So this would be a deploy-time setting which can be altered outside of the WVD environment post deployment and cause strange issues.

There's also the case of new insights into the usage of your WVD environment over time. How can we change the VM size for the hostpool if the initial sizing was incorrect?
