OpenVZ or KVM?
So considering the server that I have won, which virtulization would you think would be better for me to start with? KVM or OpenVZ? I was originally planning for Xen PV but it seems most of the answers that I have heard so far are against Xen PV.
Already had some feedback from a few senior members, but just figured I should hear a bit more pros and cons in public.
Thanks people!

Maybe you could tell us more about what direction you want to take with your new business?
Well, I won't compete for the cheapest VPS providers out there and the services will be largely unmanaged, price point will obviously be set in accordance to the platform used...is there anything else you'd like to know?
Hi,
If you want an easy to manage solution, I'd suggest openVZ - and once you get things rolling, then maybe get into KVM.

I would suggest openVZ to start. I am not sold on the KVM deal.
I am not aware of any existing KVM providers currently hosting at ColoCrossing - so that may be worth a try, if you want to offer something unique
Proxmox VE gives you best of both worlds.
What issues do you have with it, or is it all mental still?
@zhuanyi to achieve sustainability as fast as possible, which might not be a bad thing as you are on a limited timeframe, OpenVZ might be the answer.
BuyVM? They're are in Buffalo, is @zhuanyi planning Chicago?
So for openVZ on proxmox does it install the openvz container in a kvm?
I think that is the location I am given.
I do not think the product is that stable yet...
I agree that for your initial services, you should go with OpenVZ. Expect that some people will complain about it, but it is what it is.
Offer KVM once you're up and going and making a profit. Don't bother with Xen, there's really no point anymore.
@zhuanyi personally I prefer buying KVM (or Xen) and I expect to pay more. I don't know your technical skills and normally I'd say "go with what you know best" to get started with. But if you're looking to have someone else admin the node then I'd suggest going for KVM in Chicago as its less common. If you are the admin and you've never managed either, I'd say OpenVZ with a KVM chaser further down the line .
After using both openVZ and KVM I would not go back to openVZ. KVM is more isolated and the resources are guaranteed.
I would recommend KVM - you can sell windows VPS in addition to your linux VPS then
lol?
@Zen My question refers to the fact that proxmox can install both openvz and kvm, and from the way it read on the website on the same system. So i was asking if it installed the openvz container in a kvm like others have talked about doing here for backup purposes.
No, it creates both on the same host node. Allowing over-commitment of OpenVZ, and taking away KVM resources as allocated.
@Chief thanks. Okay, I was wondering. As I know that thrustvps used to have a reseller program that, the way I understand it used to install a Xen vps with openvz installed in it so that you could offer vps to your clients. Was wondering if it was the same idea.
Easy enough....
Install proxmox on the host node, create a KVM and install proxmox inside the KVM. Then cluster the two proxmox installs together Then you could live migrate for example your OpenVZ's from the host node to inside the KVM
Other option for doing both virtualisations on the single node...
Install Solus/KVM on the host node, create a 8GB KVM.
Install Solus/OpenVZ inside the KVM.
Solus sees these as 2 separate nodes, you can now oversell the OpenVZ platform inside KVM, and you can sell standard KVM with allocated resources. It will require 2 licenses but there's a way without proxmox.
Clear as mud?
So theoretically possible, highly undersireable.
Which option is undesirable, and could you explain why...
the openvz inside kvm
Fair enough, but why would it be undesirable?
You stated it was undesirable, I would like to know the reasons. Curious that's all.
KVM virtualization as you can run a lot more OSes. Like own dedicated server.
virtulization inside virtulization. Sounds like more trouble then it's worth.
If you mean windows, i would advise @zhuanyi to stay away from that sh*t. Sure, there is some market opportunity there, but the profit to trouble ratio is probably not very good.
@Zen I was wondering if the origional node provisioning, was set with a large KVM that was installed with and openvz container in it.
@Chief What @Jack said would make it undesirable.
I'd pick openvz to start with then offer kvm on the next server.
