Proxmox VE Setup

So WTF is the benefit to PVE over raw KVM for a real business?Because I am not seeing it. There are exactly zero reasons to ever do anything except hardware raid (enabling blindswap) in any real SMB today.
Without doing ZFS on bare metal, you get almost no beneficial functionality from using Proxmox VE over KVM on your Linux distro of choice.

The reason I'm in the process of moving over to Proxmox is the ease of setting up backups. It's very straightforward and if a backup doesn't work then it doesn't require someone who understands scripting to work out why.Since Proxmox backup server was introduced a few months ago, PVE has the ability to do incremental backups too.
Apart from that there's not much extra functionality.

I read through the documentation when I was labbing proxmox, and it specifically calls out that if you need replication the only way to do it is to not use a raid controller (present the drive's directly to the OS).
More specifically, they intentionally restrict it to ZFS. Which really, really sucks. ZFS is a waste of overcomplication.
Unless there has been a lot of turnover in Proxmox management, this is still the same company that insisted software RAID was unusable till they decided to adobt ZFS. Doing things weirdly and/or more complicated than it needs to be is just what they do.

Backup is a separate product. If I am moving to that ecosystem, just for a backup, I can just buy Veeam and use Hyper-V. It works better and is well known and supported.

That's true but being able to schedule backups easily from the console (even if they are full backups) is a benefit over raw KVM which was the question.
Actually another benefit is being able to live migrate between cluster hosts (without shared storage) from the console. I could live migrate stuff from raw KVM but only from the command line on the host.

Can you without using ZFS? I have not tried. as the entire design of this deployment requires replication.

I switched the default file system from ext4 to xfs.
With older versions I did experiment with changing the other default settings like swap and root partition size but that’s about it.XFS on LVM is the default now.
I just reinstalled. No, it is still ext4 by default. my bad.. too many times reinstalling. it is all blurring together.

@JaredBusch
Yes - I've done that a few times. I'm running with the default LVM.
I think it might be a little less picky about CPU options (during a migration) than raw KVM too. Though I definitely don't have enough data to say that with lots of confidence. -
@Doyler3000 you know you could do all of the same things you've mentioned with Xen Orchestra and XCP-ng too without the added complexity.

@DustinB3403
I don't doubt it.
There wasn't really any added complexity though. PVE was installed with all the defaults.
