I started migrating my customers from VMware a good three years ago.
It does help that I have thirty years Linux experience compared to the paltry twenty five or so of VMware (which was RedHat plus stuff back in day)
I also have rather a lot of Hyper V exposure too and I defy you to love its iSCSI and networking, let alone that awful vTPM thingie.
It's Proxmox for me, any day. Even when I've completely knackered it I can always boot a systemrescuecd and mount and chroot the thing back to life.
I too ran a large VDI, server, and scientific computing cluster based on Linux - libvirt in my case. I saved a bunch of money over VMware. When I quit to go to a higher paying job, they had to rip and replace everything with vSphere because they couldn't find anyone willing to work for .edu money with the skills to manage that despite the massive cost savings.
I had asked for vSphere to avoid this problem, and they balked at the licensing costs even in the good ol' days.
Libvirt isn't even difficult, were they trying ?
