Live migration Proxmox?
-
Is it true that you can't live migrate from one host to another in Proxmox - if they belong to different pools / clusters?
-
@Pete-S that's my understanding.

Thanks, I'm trying to figure out if moving from xcp-ng to proxmox makes any sense for an environment with many individual hosts.
-
@Pete-S That is what the docs say. I have never tried.
But also, why not have everything in the cluster? What is the need to make them "individual" hosts?
-
@Pete-S Why are you considering the move from xcp-ng?

Pools (resource pools) as they are called in xenserver/xcp-ng will put at lot of restrictions on the hosts.
Pools are managed as one entity (through the pool master) and works best when you have shared storage.
They are however a huge hassle when you don't have shared storage. So hosts that use local storage and are individual are best kept as separate hosts. So in this case everything started out as pools but have been migrated to individual hosts.
Maybe it works differently in Proxmox, I've only used it in the lab on a single host.

Just because it's based on debian with KVM which will not go away and we run debian on everything else.
The future of of xcp-ng's upstream project (citrix's hypervisor) is also uncertain I think. Which makes it logical to keep an eye out for options.

I have never seen this done before. My curiosity has been awaken i will probably go to you tube to check it out. Thanks

I manage multiple servers through the single IP of the cluster, but you can still directly access the individual nodes if you desire.
I do not know about resource pools and such as I have not used those with Proxmox yet. Just multiple servers in a cluster, but no shared resources more than a setup for replication at one place. But that one is only for replication, so not a good example.
