05/08/2023, 7:55 AMHello,
When trying to add a node pool to and RKE cluster (Harvester) I see that there is a limitation to 32 cores for Harvester Vms…
Is this by design ?

Whenever I type int larger than 32, it is replaced to 32

rke2I guess this limit is a defined number, for running guest k8s cluster, a NODE ( namly VM in Harvester) with 32 cores are enough at that time, when more are wanted, the limit should be adjustable. In Harvester, VM can have 200+ cores.

It does not matter what is the Limit in Harvester, if we are limited by the guest k8s template.

05/08/2023, 11:32 AMlet me double check
What is the wanted value here ? @lively-zoo-40381
We do have a limitation,, 32 is the current barrier.

05/08/2023, 1:34 PMWow, I didn’t see that limit of 32 cores per VM in the documentation.
1. I think this should be mentioned there
2. Is there a plan to remove this limit ?
3. When if at all will it be possible for Rancher to provision nodes directly on Harvester OS without VMs ?
Thank you @ancient-pizza-13099 for your time

05/09/2023, 6:26 AMWhen if at all will it be possible for Rancher to provision nodes directly on Harvester OS without VMs ?== It is not the design target. Land k8s guest cluster in Harvester HOST NODE directly will lose many features comparing to VM, like isolation, live migration, security etc.
32-core limitation is a number defined the time, as in Rancher + Harvester scenario, the guest cluster(e.g. k8s) /workload is carried in VM, anyway we need a core number to set for the VM.
