I have been playing around with qemu for a few years, and I love it. I've also dabbled with VirtualBox and VMWare's ESX, Workstation, and Server.
However, I was happy to discover that Linux now supports virtualization with qemu's help. I have been working with ProxMox since the spring time, and I really like it.
Anyway, I was wondering what the other guys are using. Does anyone else use qemu/kvm for full virt, or do you do the Linux-on-Linux thing? Is there anything better that I should be aware of? Opinions please!!!
There are various other Virtualization solution, for example parallels.com/products/virtuozzo which is nearly as famous as vMware but on the other hand there are also open source solutions like xen.org (which I recommend) and openvz.org.
We used to use and offer OpenVZ, it is very reliable and does what it does very well. It does have some limitations though, with no control over the kernel, and undesirable OOM handling.
Having used qemu (eventually with kqemu) for years KVM was a refreshing mix of full virtualization and very good performance. We have been offering KVM plans for over a year now and it has been good and is getting better.
Blue Room Hosting - High availability UK VPS KVM Plans - Multiple OS support. Virtual console and CD drive.
I'm using kvm, for some time now. I've been using Xen before, but i find kvm better, so i provision all new nodes with kvm instead of xen. At my opinion vmware esx is probably the best, but it comes with a certain price, so it depends on a business plan is it viable option or not.
i use virtualbox for desktop virtualisation and openvz for server containers.
i don't really see the point of paying for virtuozzo, other than commercial support does it offer anything over openvz?
i've gone off everything vmware, they seem to be going very windows-only with server/esx, workstation offers me nothing worth paying for and fusion doesn't have great performance on my mac mini.
i've dabbled with xen but found it too hard to manage, not tried v3 or the citrix stuff though.
i've dabbled with kvm but also found it too hard to manage, but that was before redhat did all this libvirt stuff.
i see [k]qemu as pretty pointless these days, its nice if you want full virtualisation for non-x86 instructions but you may as well use one of the products that has forked from it such as kvm or vbox for x86.
Wow, its been a while since I posted here... I'd like to come back and say that I am using Cloudmin/Virtualmin. The price is right, and it seems to have delegation built in, from the ground up. It's integrable with WHMCS as well.
