I agree. I've been really impressed with KVM-69. It has worked very=20 reliably. My story is very similar, except that I was using the free VMware Serve= r=20 (I couldn't justify the price tag for ESX). In short, KVM came to save= =20 the day and I get much better performance than I did with VMware. My=20 setup is for a two-node cluster with DRBD and OCFS2. The ability to=20 migrate VM's so quickly is wonderful. I too wrote my own scripts which= =20 I will share in a few months once I'm done fixing bugs. Yes, KVM is very easy to install, manage and use. It is even better=20 when you write your own scripts. It's wonderful to be able to manage=20 things in a way that best makes sense based on your experience and=20 infrastructure. Thank you to the KVM team for all of your great work! --=20 Alberto Trevi=C3=B1o alberto@byu.edu
