What to set VM vCPU as default?

[maxrebo]

I'm new to Hyper V, when we create a new VM, its sets the number of virtual processors to 24, wondering what everyone sets their default to?

Obviously depends on what the servers doing but the one I'm currently setting up would be for WSUS and a few other minor roles.

 

Thanks

1 as default unless it’s a high priority machine then 2

 

Anything else I normally wait to see how it performs before increasing it, as remember vcpus don’t compute directly to real cores

Depends on your server CPU, if you have a ton of cores/thread then go ham.

 

If not a lot 1/2 per machine unless higher load (e.g ruckus used to need 6+ IIRC)

Set default as 2 vCPU and increase according to requirements. Why give a virtual machine running Unifi controller all the CPUs :-). Does a Domain controller require 24 vCPUs prob not.

Enough so the total vcpus = the number of cpus
