I know VMWare works great for a lot of people, but it was always just a thorn in my side. Almost a decade ago my small company moved from VMWare to ganeti, and we've been really happy with it. At the time we were running a SAN and the small VMWare Essentials license. But managing it with Windows was painful for me personally, and our HP SAN was kind of painful, every year like clockwork it would just stop processing until we had remote hands reboot it. And every year they'd tell us "Try this firmware" to shut us up for another year, until eventually the product reached EOL. We had been running ganeti in our dev/stg cluster for years at that point (and the python.org infrastructure was using it at that time as well), so I decided to transition us to local storage running VMWare and then to ganeti. Doing local RAID array monitoring on VMWare was quite painful at the time, maybe that's gotten better? I absolutely love that ganeti has such a good suite of command-line tools for operating. I have a small shell script that respins half our dev/stg infrastructure every other day. Our entire critical infrastructure is HA at the machine level, so we don't play around with anything like live VM moves, we just do offline moves. I used to do the drbd-based replication and live moves, but the doubling of disk writes and committed disc usage wasn't worth it for us. Proxmox is on my radar if we needed to move away from ganeti, but so far we are looking like we'll stick with ganeti.
