We are currently planning to make some VPS'es for sale, however we are unsure about whether we should use OpenVZ or KVM.
I know that OpenVZ is lighter and easier to use but on the other hand KVM is more advanced.
Could you please give recommendations on which technology to use? And do customers prefer OVZ or KVM more?
Thanks in advance.
Just started a hosting company reselling KVM's. Generally speaking, KVM is better preforming but more complicated than OpenVZ. One important limitation to OpenVZ is the fact that it doesn't support multiple kernels. Therefore, OpenVZ containers can only be Linux, and once they are created their image can not be changed.
It's a personal choice, it seems. Both options will serve you and your clients well, assuming the rest of your service can.
kvm is more stable and runs like a dedicated box because everything is truly isolated. Also kvm is centos' supported virtualization choice and comes packaged with their distributions. Since we only use centos v6 we are solely going to use kvm from now on. Openvz is ok for light customers but if you have high end customers with lots of usage and processing it won't be a good choice long term unless you really know how to optimize it.
I'd say this thread is a great example of market research.
I would say it is a Terrible example of Market research!
First off, nowhere has the OP established whom his clients are going to be - the first thing you need to Identify is the Market.

Nope, I would not say Proxmox is great, it is an Example of a hypervisor solution that will allow mixed container types, so you are NOT limited to a single technology when starting out before having (multiple) nodes for OpenVZ and KVM if that is what is ultimately chosen.
