Couple of items, I've used Promox for about 4-5 years  now, very nice
hypervisor have had no problems what soever
I current run it on a Dell R-610 with 96Gig of ram and 6TB of HD, hosting 5
linux servers and desktopsetup with about 8 domains and 1 email server all
are Linux based, the mail server is awesome
system called Zimbra completely free, I'm hosting a number of open source
decentralized social network, Peertube (Youtube work alike) , Mastodon
(Socal Network) , Piwigo (Picture hosting), OSSN (Social Network)
, WebTrees (Geniology), OsClass script (ForSale/Want ads), Simple Machines
(Forum), WordPress (Blogging site)
So I use it alot

I might also recommend highly the use of Virtualmin as a hypervisor I have
used it for about 2 years and am a subscriber to both systems
Proxmox cost me 175.00  a year two processors 75.00 each for
updates/upgrades and the Virtualmin is 7.50 a month for updates/Upgrades

I might also say the virtualmin really has a nice routine for easy
installation and renewal of Lets Encrypt
