Sylen, check out XCP-ng. Barely any difference unless you get into a state where you had a single storage setup (say RAID10, 4 disks) and suddenly all VMs need to write to disk. However, professional setups use SANs and don't have that issue. I have ten Ark servers on two identical Xeon setups, and they never choke out.
I am wondering if the Data store from ESXI seven days doesn't handle well. As HyperV is direct to storage.
