Kimsufi is a budget brand under French company OVH, specializing in renting high-performance servers at extremely affordable prices. I personally rent the KS-4C model, featuring an i5-2400 processor, 16GB RAM, 2TB HDD, 100Mbps unmetered bandwidth, for just 13 euros/month. Its exceptional value makes it perfect for running virtual machines for experiments. VMware ESXi (now also called vSphere Hypervisor) and Proxmox VE are two popular operating systems specifically designed for virtualization, both available for free. Crucially, Kimsufi's control panel offers one-click installations for both systems. However, during my usage, I found that Proxmox VE frequently suffered from unresponsive remote VM connections (VNC black screens) or keystroke loss (especially critical during password entry)...
