Proxmox VE is a complete, open-source server management platform for enterprise virtualization. It tightly integrates the KVM hypervisor and Linux Containers (LXC), software-defined storage and networking functionality, on a single platform. With the integrated web-based user interface you can manage VMs and containers, high availability for clusters, or the integrated disaster recovery tools with ease.

I love to hear this. I admit tho, I thought Proxmox would explode after VMware imploded. Proxmox did not just step into the gap left by VMware. A very large portion of IT has still never heard of Proxmox and could not tell you what its for, while they all have some passing understanding of what VMware is.
I was hoping for a sudden swell where companies were moving ESXi > PVE en masse ... and hiring engineers at high dollars. I don't see that. :[
Not gonna be a sudden swell, but there will be a raising as contracts start running out and beancounters start looking at running costs
Many places are still looking at options, and costs of switching. Where I work still is, even though we have a large Linux server fleet already. I expect this is on a 3-5 year plan to ramp up switching to something else for most companies that are going to switch.
Perhaps this comment most addresses what was on my mind. I see comments from admins, education, small biz, homelabbers (homelabbers rule!).
There are only a couple folks that appear to be in my tier (50 + hosts). And that's because there arent a lot of us on proxmox.
I think you're right. Big enterprise moves slow. The VMwsre implosion is just now hitting corporate budgets.
Thanks for your perspective, friend.
We are a vdi shop too, so we have to be sure performance is at least as good. With a few other complicated setups, it is non-trivial to test alternatives.
Migration is usually shutting down the VM, exporting it from VMware, and importing on the other side. We have some really generous maintenance windows usually(ie basically 36-48 hours every weekend) and I would still expect it to take a year to migrate everything if we went all in.
We would be over 50 hypervisor hosts too, san connectivity, shared disks, and GPU accelerated vdi. It's a lot to eval for each option and test it all works and figure out the caveats.
