I've had good success using partitions as source drive in KVM. This offers better performance (compared to qcow2 or sparse files) but it does require to do some planning ahead. If possible I use DRBD partition so I can have a hot backup server ready (ideally I would run 2+ VMs on 2 servers, each running half of the VMs and at the same time providing backup for the other node). Plus it's easy to access the guest drive when guest is shutdown using kpartx.
