Re: Meanwhile…
and here we are in 2026 and KVM-based stacks still can't compete with where Vmware was 16 years ago with version 4.1 in some cases anyway

See the laundry list of new features that came out with that build, 4.x was the last version of vSphere I was really excited about, everything since has been meh mostly just security updates and new hardware support.
For me personally, a solid VMFS replacement would be nice, GFS2 exists, though it seems outside of HPE VM Essentials nobody is willing to risk fully supporting it (as far as I can tell anyway). I didn't realize this myself till I looked into it much deeper late last year. When El Reg posted about a new Xen Server today or yesterday I checked their docs again, and there is no real change.
vSphere APIs for performance monitoring with 3rd party tools(I use LogicMonitor), unsure if KVM-based systems have anything remotely resembling that(or the degree of depth that the data that is provided). While I don't need the feature myself I did poke around to try to see if there was any KVM-based solutions that provided equivalent to vSphere's "fault tolerance" feature but came up empty(other than some discussion from Red Hat I think speculating whether or not they need it, and that was many years ago).
The fact that T-mobile only made 2 support calls is testament to how rock solid the vSphere platform has been. When I was using it for work maybe I reached out to support 4-5 times over a decade(small installation). I stayed behind the curve in versions, with a conservative configuration and shit just never broke. To be clear the ONLY things I cared about from VMware was ESX/ESXi (preferred ESX), vCenter, and VMware Workstation(and VMware GSX/Server two+ decades ago). Never gave a shit about the 90+ other products they tried to sell since ~2012.
I still run ESXi 6.7+vcenter 6.7 in my personal colo on old gear, will look to replace it with something else when I refresh hardware again maybe around 2030.
Have been using VMware since before v1.0 was released on Linux back in 1999. I misplaced my "VMware for Linux 1.0.2" CD maybe 15 years ago, was a nice bit of history for me anyway. I did keep several of my vmware downloads, I don't know why I'll never use them again but I can't bring myself to delete them(and they only consume 2GB of disk space, so it wouldn't save me anything)
From ~6MB for vmware 2.0.3 (before they renamed it to "workstation") to almost 400MB for VMware workstation 17.
