What server virtualization systems does Enterprise use?

Question

virtual box

Hello!
Tell me what server virtualization systems do you use?
Has anyone seen using VirtualBox on a server?
UPD:
Essentially. We have VirtualBox. Works crooked. Where is the best place to go? A maximum of 10 virtual machines will spin on the server. All under Linux. It is important to back up with minimal downtime.

Answer 1

Enterprise is different. Everything is used.
I have seen large installations (from 100 hosts): KVM, Xen, VmWare, Hyper-V
You ask a question on the merits, and not out of academic interest.

Answer 2

Enterprise lupus est :) A lot depends on the tasks, on the budget, on the acceptability of pirated software. Usually "we say Enterprise, we think - Vmware", but this is true either for those who have a sufficient budget, or for those who are not afraid of pirates, because honest Vmware with whistles and squeakers is sooooo expensive. And so it certainly has everything you need.
You can try KVM - if you find a suitable face - libvirt is undoubtedly a good thing, but for a true commandline enterprise it will be difficult.
Hyper-V is good to use when the host is Windows and the guests are all Windows. Moreover, a full-fledged Hyper-V, as well as a full-fledged Vmware, is very expensive, although the basic one is given for free (included in the delivery of Windows)

Answer 3

We use kvm at work, since almost everything is Linux. It all spins on Debian.
My opinion is; I would move from virtualbox to kvm. It's not hard to do it there. There are instructions on the Internet. If you don't find it, write me, I'll help you in any way I can. He himself personally endured and not one.
And so, you have already been written: decide on the level of the enterprise. What do you want to have as a result, what budgets are ready to consider for all this?
PS: xen did not offer, because he did not work with him from the word at all.

There are many factors that influence the choice. And you need to describe the criteria that are important to you in the conditions of the task, what is the purpose of the guest OS. How are you going to maintain and back them up. And what will happen if your server breaks down, how will you transfer data? It must be remembered that one hypervisor can immediately disable several services at the same time if the server on which it is running is not backed up and accidentally fails. The entire IT infrastructure of a small organization may stop functioning.
For example: if you have an OS in which the database server is installed, then it is better to use container virtualization, since some virtualization systems cannot automatically increase the size of the guest OS disk. And what happens if the disk is full? You will need to manually reconfigure the disk image, expand it, etc. If you have a simple website on a guest OS, then you can use non-container virtualization. If you need a specific kernel in Linux OS, container virtualization may not be suitable either. The devil is in the details.
The latest trend is container virtualization on Docker.
For your case, Proxmox is most likely suitable, it has both OpenVZ container virtualization and regular KVM.

Answer 5

Good advice has already been given. But I want to note that under hyper-v, Linux guests work fine. Moreover, Hyper-V is a free version without a GUI. Manage it from the user host. The main thing is to make backups. It depends more on the tasks. Do you need a "live migration", replication to another host, and all sorts of goodies. From Linux hypervisors I use KVM, Proxmox. Everything works great.

For some reason, they didn’t say about xen .. There is also a free license, though with certain restrictions, but it all depends on the needs. Hyun consumes little resources there is an application for easy control from any PC..
