Short post to say that the support for KVM in Fedora 10 rocks! We have been in the process of removing our current VMWare Server infracstructure in favor of an free alternative for some time now.
We run Linux on 99% of our infrastructure, so three years ago, we tested vserver first. The results was not that bad but it wasn’t good enough to put our production servers on it. After that, the Xen trend give us hope. But, it has short lived after seeing all the hacks that one must do to barely run a stable OS on it. So, back to square one…
Recently, KVM is the new “cool thing” in virtualization space. It’s been out for some time but we just recently give it a go. We made our tests with Fedora 10 beta and it’s been such a pleasure to work with. Virt-manager is simple, fast and stable, Fedora ship with recent version of all the tools, the guest OS support is really good! We now have three production servers and a couple of tests machines running a stripped Fedora 10 install with the KVM tools. There is approximately 25 virtual machines running on them that replace all our old servers. The good thing is that if we need more power, we just buy a new server, put the Fedora 10 DVD in, start the installation with kickstart, reboot and everything is ready. Unboxing to production : 30 minutes!
Sure, KVM and the management tools miss some features to really be on par with VMWare Server. But, I think that in the near future we will see the gap close with the maturation of projects such as oVirt and virt-manager.
