Yeah, if you have a few virtual machines for specific purposes, there's not much point bothering with some abstraction on top of qemu.
I also have just a few 20 line scripts to run my VMs, and that's all. Works with no changes/hassle for 5 years already or more. No extra SW to learn. Man qemu gives me all the answers. Easy.
I guess if you want to manage some complicated setup and dynamically add/remove disks, network cards, or whatever, all the time, migrate machines, etc., some solution like virsh would be good, but for having everything on one bridge, in one subnet, to run some throwaway VM with Windows/browsers for web testing, the simpler setup is so nice.
