I am looking for a Server oriented distro that we can expect have decent support but also offer as much as possible some of the latest features that KVM might offer.
I am leaning towards Ubuntu LTS 10.04, because well it's LTS and more bleeding edge, but I find Ubuntu not serious enough in terms of support (I say this a heavy Ubuntu user). Given that Centos 6 is not out yet, I am not sure if going Centos 5 would be the best option in terms of getting more features from KVM.
Any other distro you would recommend that could meet the criteria of long term support? (At least 4 years)
