[slurm-users] SLURM in Virtual Machine

[von St. Vieth, Benedikt]

Dear José,

what exactly do you want to put into a VM?
Computes? Slurmctld/Slurmdbd?

We are running slurmctld/slurmdbd in a VM for some time now, but only for a small Cluster (14 nodes).
The computes are still bare metal.

Until now we do not see issues, also live-migration of the VM to another host works without disruption.

best regards
benedikt
