Which virtualization tool to choose?

Question

linux

Good day. It is necessary to raise 6 virtual machines on the server (guest OS: Debian and Windows Server), a couple of sites / forums, a mail server, and self-written server software will be hosted in the guest OS. 100 people will use it at the same time.
Which virtualization tool to choose and which OS on the host?
There are not many comparisons on the wiki:
Name - Principle of operation -
Hyper-V guest OS speed - Hardware virtualization - Close to the performance of the host system / lossless.
VirtualBox - Dynamic recompilation (based on QEMU) - Virtually lossless if
VMware Workstation extensions are used - Virtualization x86 - Virtually lossless if extensions are used
What extensions are needed for VirtualBox? Oracle VM VirtualBox Extension Pack?
What extensions are needed for VMware? If she has x86 virtualization, then the guest OS should be only 32 bit?
If I give each virtual machine 1 processor, and on the server 2 or 4 processors, how are they divided?
Should I choose
"Windows Server + Hyper-V" or
"Windows Server + VirtualBox" or "Linux Server + VirtualBox" (would there be any difference?) or
"Windows Server + VMware"?

Answer 1

In your case, any "adult" virtualization system that you know (Hyper-V / VMware ESXI / Proxmox)
