Virtualization. Help me choose

Question

Virtualization

Greetings. I wanted to make a server with virtualization at home in order to scatter all sorts of junk among virtual machines and turn them on as needed.

Iron is not weak, 6-core xeon and 16 GB of RAM.

From virtualok will be:

• Openfiler/FreeNAS hasn't decided yet to manage the storage (approximately 8 TB). Clients will mount over NFSv4, another one over CIFS (samba)
• P2P virtual machine. Torrents, DC, aMule, sBorg.
• Media virtule. I'm thinking of throwing a video card there so that you can encode movies that go through DLNA. So I understand here you need to take something with CUDA support ...
• Some distribution of Linux, most likely arch, for sorting the media library and GNS3 (cisco emulator), well, and other desktop tasks.
• A bunch of -dev virtual machines that won't run 24/7, like a deb build machine.

What I would like from virtualization:

• Adequate hardware support. For example, Areca raid controllers - it will be loaded from it.
• Snapshot support.
• Ability to limit the number of CPU cores (with HT there will be 12)
• It is desirable free of charge, it is possible as a beer. Paid products are also ok, the main thing is that it does not cost like a Kommersant enterprise.
• An extremely big plus is the presence of a web panel. Or an adequate cli. I don’t have Venda, so esxi with their dot-net client goes through the forest - it doesn’t even start through wine / crossover.

In general, what I see from the options:

• XenServer
• CentOS + Xen + some kind of socket. Didn't find the right one.
• VirtualBox + phpVirtualBox. It's bad, because the web panel works very creakingly. Cli is quite hard to remember.
• What are your options, gentlemen?

Answer 1

VMware now has one copy of ESXi free, but with some limitations. It seems no more than 4vCPU per virtual machine.

Answer 2

Xen or KVM.
I'm not 100% sure about xen's ability to stream videos, but I've seen recipes on the Internet, I just haven't tried it myself yet.
If VMware doesn't support your controller, then it won't, in my opinion. At least I couldn't get it to pick up on my 3Ware's wide popularity.

Answer 3

OpenVZ

Answer 4

I use Citrix XenServer, unfortunately the free client for it is not yet fully functional, but since I still have Windows for games on my computer, this doesn’t really bother me.
