hi there

xen is dominant in vps's but its hardly superior. ibm and redhat have both abandoned leaving it as a kernel fork with limited major developers, it whilst kvm has been merged in to the mainline linux kernel.

Xen is superior for VPS providers and other types of hosting. Here you need to control the distribution of resources (and cpu time) according to type of client.

KVM is superior for other types of virtualization like the testing of applications for developers.

RedHat likes being the boss and need "to control" the development of keys products. It's not bad thing but is the truth. In Xen they aren't the boss.

IBM doesn't use or promote DragonFlyBSD but it's not reason for to kill DragonFlyBSD. Right? :)

Oracle is investing in Xen. And the mainline Linux kernel has support for Xen Dom0 and Xen DomU. Xen has been working in the mainline Linux kernel for a lot of time.

Amazon EC2 uses Xen. If you want to have DragonFlyBSD in Amazon, firstly you need support for Xen.

virtio has also been adopted by virtualbox, so virtio drivers would cover two virt technologies.

Yes, virtio is great. I don't discuss it.

the main restriction for vps providers is that the kvm support in happy commercial vps gui software is very limited at thus stage.

It's not the only problem. The providers can develop their own software panel.

on the other hand private cloud software is heavily falling behind kvm.

also, openbsd has vmware drivers now. which could be merged.

my 2c

Cheers :)
