After Redhats decision to put the source code of RHEL behind a paywall, I am getting a little bit concerned when it comes to open source software owned by companies.
What are your opinions/thoughts about Proxmox ending up doing something similar for a cash grab?
I understand the feeling, but I don't think there's a rational reason to be concerned at the present. If a multi-national company buys Proxmox, then maybe it'd be worth formulating a fallback plan.
Just to play through the scenario (and assuming there's no fork), I think I'd probably recreate my current infrastructure using all of the component pieces that Proxmox does—KVM, LXC, corosync, ZFS, Debian, etc. When you get right down to it, PVE is mostly a UI (and a great one) for existing technology that could be setup independently.
Thank you for sharing your opinion. I probably should learn to set up a cluster with pure kvm, maybe libvirt just in case. If I have had the time for it right now, I would, but proxmox makes it dead simple.
If you dig have a web GUI, I understand Cockpit (which is in the repos for Debian and Ubuntu) has some capabilities for managing KVM and LXC. I haven't played with it, but it might be worth a look.
