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 :)
