[slurm-users] SLURM in Virtual Machine

[Jose A.]

Dear all,

thank you for your fast feedback. My initial idea was to run slurmctld and
slurmdb in respective KVMs and running while keeping the worker nodes
physical. From what I see that is a setup that works without problem.

However, I also find interesting some of the suggestions that you
mentioned, like having worker nodes in VMs for testing and compilation
purposes or even the login node. I will give some thoughts about that.

Thanks a lot for the support. You are great.

Well, technically I have run several clusters all in VMs because it is
all in the cloud.

I think the main issue would be how resources are allocated and the
need. Given the choice, I would not run nodes in VMs because the
hypervisor inherently adds overhead that could be used for compute.
However, there are definite use cases that make it worthwhile.

So long as you allocate enough resources for the node (be it the
controller or other) you will be fine.
