Isolate cores to VMs only when they are running?

[hpka]

Simple question that I've Google'd several times. In short, can I isolate a CPU to VMs only when they are running.

I.e:

• If the VM is running: Only it can use it's designated cores
• If the VM is not running: Anything can use them

In short, you can't.

 

In long, it kinda is possible simulate it by having 2 separate sets of dockers and a set of bash script but it's not true isolation.

Appreciate the straight answer

I'll go and search the feature requests forum now and write it up if I don't find it.

EDIT: Done the feature request.

I’ll be interested to see if you get any traction.    I thought isolation could only happen at boot time and if so that will mean isolation cannot be dynamic.

You can set isolation in Settings > CPU Pinning at any time. Isolation can only happen at VM boot time I admit, but appears to otherwise be available at any time at the host (i.e. UnRAID) level.
