Depending on your organization, if you can solve a problem with Debian (and Qemu) you can solve a problem with Proxmox.
If you can solve a problem with Debian and Qemu Proxmox gives you nothing. Better to just use same automation you use for VMs to just keep fleet of bare Debian + KVM machines. Proxmox is for when you don't have a bunch of Linux experts on board. And that's also kinda what enterprises want to pay for, removing "liability" of having to keep very competent team. ...the fact that ends up costing them more everywhere is o…
