Hello,

We want to buy a new server to build vps hosting for clients.
I know that Openvz can't use the asl kernel! and can't run windows
So i like to know what's is the best way to setting a vps hosting with the asl kernel.
Xen will provide windows also and it can load the asl kernel?
But use Xen a shared kernel or every account a own kernel?

What is the best way and the most secure way to setup a dedicated server for vps hosting?


Thanx in advanced

Hmmmm....

If you don't want to go OpenVZ/Virtuozzo (which is actually the best option in terms of resource usage) then VMWare is the most mature, professional option (IMHO but I'd be greatful for other views).

Remember that it isn't enough to offer a customer an SSH login. You need to provide them with a Console (to reboot, see errors, reimage, whatever), a backup solution, and all sorts of other things.

p.s. I have no idea if VMWare offers a per-user console or any other options aimed at VPS provieders, out of the box or through third parties etc etc etc

KVM would be the other option, its just like vmware but built natively into the linux kernel. They added support to it in RHEL/CentOS 5.4 if I recall correctly.

Internally we replaced our vmware servers with it, and it has both web (ovirt) and desktop (virt-manager/libvirt) clients.

You can also run ASL as a xen guest (they have a funny name for it that I cant ever remember)

Proxmox may therefore be a great option, combining KVM with OpenVZ.

Faris,

OpenNode looks similar to Proxmox, but is based on CentOS instead of Debian.

Thinking about it, the big problem with either of these projects is what happens if they stop being maintained.

The kernel is the OpenVZ kernel modified to support KVM, which means that if the project gets abandoned then you are out in the cold. This is far too risky for commercial VPS hosting.

Faris.

Well, it's all just OpenVZ/Xen/KVM underneath, so I guess you could always move your virtual machines to another setup that uses the same technology.

Very true.
