My name is Tucker DiNapoli and I'm going to be working on libvirt this summer for the google summer of code. My project is to implement job control in the storage driver. In order to do that I am first going to create a unified api for job control in libvirt (as it is currently implemented seperately in both the qemu and libxl drivers). I'm currently working on the api for job control and I have some ideas that I'll post on the mailing list soon. If anyone has any ideas or requests re job control I'd be happy to hear them. I'm on the #virt irc channel as tuckerD, I look forward to working on libvrt this summer.
