LowEndBox - Cheap VPS, Hosting and Dedicated Server Deals

Poll: OpenVZ VPS, KVM VPS, Xen VPS or Other?

OpenVZ vs KVM vs Xen vs Other Cheap VPS

Welcome to our second-ever Poll on Low End Box! Last month we asked you what you use your VPS for and this month we are back with another question.

There are plenty of different VPS/Hypervisor technologies today, from the common OpenVZ, KVM, Xen, VMware, Hyper-V and so on. Do you prefer the high allocation of shared resources that OpenVZ provides? Or would you rather have dedicated resources akin to KVM and Xen? Or perhaps you prefer the enterprise-first approach of VMWare.

If you are looking for some more information prior to voting, a few years ago we wrote a comparison of OpenVZ, KVM and Xen and more recently we’ve highlighted some of the strengths of the OpenVZ and KVM architecture.

We want to know what you prefer. Remember to vote and then leave your thoughts in the comments below. Thanks for taking part in our Poll!

    • KVM is leading now with almost 75% of the votes. Very impressive.

    I’ve been happy with the openvz services that I’ve used, except you’re sometimes at the mercy of your provider. I found the clock was incorrect on a host that propagated down to my openvz container, there’s no way to using loop devices, from what research I did, so it’s impossible to mount a VFAT on disk file system. Fuse, unfortunately, doesn’t provide all the features of the real kernel drivers for the FS. ipsets didn’t work, not sure if that’s still the case. It’s also much cheaper to procure openvz services, it seems, due to the nature of the shared resource rather than dedicated that KVM offers. That said, if all things were equal in price and features, I’d go KVM every time.

    • Agreed that OpenVZ has had its place in the market — and in some cases is still quite useful but with KVM options being so affordable today it’s hard to say there’s still a reason to consider OpenVZ.

  3. KVM is dominating! We noticed the same, for every 30 KVM nodes we had 1 OpenVZ node, the demand for KVM eventually led us to discontinue future sales of OpenVZ.

    Here’s an awesome KVM VPS deal: https://my.racknerd.com/cart.php?a=add&pid=57

    Yes KVM also recommended by SlickStack for easy scaling of high traffic WordPress, because resources are more controlled in the container. However many people don’t realize CPU is still technically “shared” in KVM and also can be over-committed (maybe like network is cheating you if dishonest).

    Even though KVM is scaling better, it still requires honest and skilled datacenter engineers. Ironic that some other containers can actually protect CPU resource better.

    Maybe something like “KVM 2.0” will be best.

  5. I was surprised to see KVM have such a big lead over the other options.

    Will be interesting to see the results as more votes come in. Already over 200 votes :)

    While I get the appeal of OpenVZ giving more resource-bang-for-the-buck if you prefer Linux, it’s a non-starter for me because I usually prefer to install FreeBSD or OpenBSD. Most of the other non-KVM options price out higher, so it’s almost always KVM for me.
