Xen Community:


As many of you are aware, the Xen 4.0 hypervisor is due to ship tomorrow (shhhh, don’t tell anyone) and I wanted to get submissions underway for Xen 4.1 features. I have updated the Roadmap Wiki page (http://wiki.xensource.com/xenwiki/XenRoadMap) with a new section for Xen 4.1 features to be added. Feel free to add your ideas or send me your features and I will update the wiki. I also plan to update the Xen.org roadmap page at http://www.xen.org/products/xen_roadmap.html to be a list of 4.1 features tomorrow, after Xen 4.0 is announced.

These might not be wishes for 4.1 as some may be too big but they're my wishlist anyway. Note they also might not be things that belong to the Hypervisor but rather to tools associated with.

  1. Make qcow2 actually work and include backing files.
    1. If it can't be made to work then it should be taken out and not mentioned in the docs so we don't waste weeks trying to get it to work.
  2. Figure out why you can't start a VM with a disk image residing in a ramdisk (bug?)
  3. Nesting
    1. As silly as this feature sounds it may be why I leave Xen for KVM. This would be useful for teaching management of VMs. A student could have a Dom0 and start up DomUs inside it without each on needing their own physical machine.
  4. Install PV DomU from CD without FTP/NFS tricks.
    1. I don't care how it's done but it would be nice. The "install from network" shuffle can pose a complexity for people getting started in Xen. I'm aware that HVM does this because of it's use of Qemu but it would be nice everywhere. Maybe as Xen moves to Hybrid VMs instead of PV/HVM this will no longer be an issue.

I'm sure I'll think of others but that's off the top of my head. Like I said maybe some of it would be Xen 5 stuff, I don't know.
