I've configured a server to support our development team and test a potential configuration for production.
I initially tried to configure Xen only do discover Dom0 is not supported in 8.10 (http://ubuntuforums.org/showthread.php?t=990180), but KVM looked like an attractive alternative. After some trail and error I got a VM working with virtio_net and virtio_blk with the image on an LVM2 volume.
While I'm unimpressed with the net IO and CPU results, the disk IO is less than desirable. Looking around the discussion board I came across this post
http://ubuntuforums.org/showthread.php?t=972526&highlight=virtio
Which leads me to believe something isn't quite right with my configuration. I've attached the XML dumps from libvirt for vm01 (file based image) and vm02 (lvm based image). I've also attached performance benchmarks from the host system and both VMs. While running the benchmark on the host I shutdown both VMs. While benchmarking the VMs I disabled the other.
If anyone out there has any insight, it would be greatly appreciated. I would love to get this working and deploy KVM over VMWare ESX.
