Ask multi-virtualization topic - chanalku91 - 01-03-2019
In addition to HyperVM, KVM, Xen, and OpenVZ, whatever virtualizor you know
I want to know more about this so I can choose the server with the fastest virtualization
RE: Ask multi-virtualization topic - Mashiro - 01-03-2019
- Microsoft Hyper-V (not to be mistaken with HyperVM)
- VMWare ESXi/Workstation/vSphere/Fusion
- Nutanix
- Virtualbox
Also https://en.wikipedia.org/wiki/Comparison_of_platform_virtualization_software

Uhmm, thank you but in your opinion which one has a stable performance
RE: Ask multi-virtualization topic - Mashiro - 01-06-2019
I would recommend KVM (opensource and free) or VMWare (if you have the money). Both are absolutely stable solutions and have great performance. KVM is huge in the VPS business and generally if you need proper hardware virtualization but it is also very advanced and needs a lot of knowledge to operate it on a higher level than the basics. VMWare is mostly a enterprise solution (atleast the product lines I mentioned above) that is used world wide by many multi million dollar companies and etc. It has many options and features, too. Also proper and advanced hardware virtualization. For private use VMWare has free products but they're rather short on features as they pretty much just have the basics.
If you're a huge fan of Windows you can use the onboard Hyper-V solution. We do that at work and it is kinda ok but I don't really like it that much to be honest.

You should only use virtualization in dedicated server . Not a virtualized environment like vps or even vds .
Openvz give less overhead since it virtualize on higer level but you stuck with 2,6 kernel and linux only . Kvm on the other hand can run any kernel and any os butnit have higher overhead and that is why openvz is cheaper
Docker Is more like container than virtua; ,achine you should able to run on kvm vps . Openvz isnt aupported due to that older 2.6 kernel
RE: Ask multi-virtualization topic - Mashiro - 01-06-2019
OpenVZ, Docker and LXC and other similar so called "container" virtualization technologies are pure software virtualization. Hence the reason why there is minimal to absolutely no overhead. However this kind of virtualization is bad after all as it emulates a very limited system without any kind of hardware passthrough and features. OpenVZ and LXC are a bit better than Docker as you can still have your own container that runs your own OS with full root permission, its "kinda" own filesystem and etc.
Nested virtualization is a whole different thing. But basically if done right you can run any virtualization inside a already hardware virtualized machine. E.g. OpenVZ in KVM, Docker in KVM, KVM in KVM and so on. The same will not really work with software virtualization (or if it works it will only work with certain emulation and the usability and performance will be rather bad).
Overhead is also its own topic that needs to be considered.
My2Cents. I'm in for hardware virtualization if you need a full machine. If you want to have something quick and only for certain applications Docker might work or if you still need kind of your own full OS then OpenVZ/LXC will do better.
