Migrating off Vmware-Server, but where to?

I've recently started using partitions for my disk devices with VMWare and
KVM. They work well, (as in no problems yet.) My original KVM setup hosting
a windows vista client, had extreemly poor disk IO performace. The disk 
was defined as a file on my OS. When I switched to using a partition on 
a free
disk I had, the disk IO improved dramatically.
