Why do people choose OpenVZ?
Hey all!
I'm trying to get an idea of why a customer would prefer an OpenVZ VPS vs. KVM. Right now we're still offering both, but OpenVZ seems to still be very popular. My assumption is price, because just about every provider (including us) offers VZ cheaper than KVM.
I don't want any concern over the reason I'm asking, so I'll just put - I'm in a conundrum because of circular dependencies around SolusVM, OpenVZ 7/9, and CentOS 7. Don't worry, we're not dropping OpenVZ anytime soon, I'm just doing some preliminary research for the purposes of maintaining our legacy platform.

Price, nowadays KVM is as cheap as OVZ, so no point.
However, things like NAT VPS are only possible thanks to OVZ, and due to the price I guess people don't care about that anyway.
I'd happily convert my existing OpenVZ hosts, including the one at RamNode, to KVM in a heartbeat.
Really
Why? Can't a KVM be NATed? Or an LXC?
Sorry, but NAT is for containers only, technical not possible with KVM.
If you use NAT in your private lan, you a wizzard, go get a /24.
b-but your signature literally says "Free NAT KVM"
The cake, The spoon, all lies, so is this.
Of the three, I have a strong suspicion which one is making you run in circles and it'snot OpenVZ and it's not CentOS.
Price of course, they're always tough to play with
In the past, it was just cheap, but now KVM is common, so OVZ is no longer an advantage.
NOVZ THX
Those people buy what is cheapest. Not all applications/workloads require full virtualization
lol, the result is expected.
i got one from ramnode indeed because of pricing. however cancelled as it can not replace the flexibility of KVM after all.
I assumed because OpenVZ can be more shared, the provider can offer me higher specs at the same price point, because those resources are essentially available to more than 1 customer. As a customer, I know that because I have 4 CPU and 12GB ram, it doesn't necessarily mean I can use them all, all the time and I should treat a large portion of those resources as shared, but, should I need them for a few hours, they will be there. Although, I really do wonder how correct that is?
cheaper
I hope it's the new LXC platform, with less performance loss.
From a customer point of view, KVM is better and more secure, but OpenVZ is cheaper.
From a dedicated server owner point of view, if you are the only user of the server, OpenVZ/LXC is better as it uses less resources per instance/container compared to KVM.
Unique feature of OpenVZ is dynamic resizing.
RAM and diks can be resized without a reboot.
This is only useful on very small servers, such as those on MicroNode Instances platform.
I assign 64MB RAM to each single-purpose container, but enlarge them during upgrades etc.
(I hope @natvps_uk can enable resizing features on more locations.)
honestly the single question no one answered me
The reality is, KVM won. OpenVZ is largely a thing of the past.
In the early 2010s, servers were expensive, so OVZ let a VPS host oversubscribe and save a lot of money. That's how early LEB/LET hosts worked: cheap OVZ boxes!
Servers are cheaper now (more expensive than 2019 though) so we moved towards KVM. The rise of DigitalOcean and Vultr also forced LEB/LET hosts go KVM: even if LEB/LET is cheaper we still have to compete with the heavyweights.
On top of that, people want Docker and Dockerized apps, some people want their Windows or FreeBSD images. These are things OpenVZ can't do easily, if at all.
Affordable, but I still prefer KVM.
It's certainly annoying for me that we can't use disk swap as extra RAM in OpenVZ servers.
In OpenVZ servers, the provider could easily copy files for me if the VPS is broken.
You still need to mount the file system which you need to do in KVM as well. I assume ppl are no longer using simfs these days.
Could you elaborate? Why is not possible with KVM? I am doing NAT and forwarding with everything, from LXC to VMWare.
Buy vps from ovz because of the price
Use ovz on your own device because it saves hardware resources
Very cheap.
LXC is simpler for own usage, I havent found a case to prefer OVZ over LXC in my private nodes both at home and with providers.
I use LXC. Pretty nice.
Not to mention IP space as well.
One can change IP assignment on KVM and dedicated server just as easily.
This is not unique to OpenVZ.
