Hi Daniel - I have an implementation underway right now, with both HAL- and Devkit-based "drivers". We have some folks who need this *next week*, so I'm trying to get the most functionality finished up today and this weekend. The generic (HAL/Devkit-agnostic) framework is essentially done and tested (except for a few odds and ends like some missing virsh fns). The HAL-based driver is ~80% done. The Devkit-based driver isn't very capable yet, mostly because of the limited Devkit functionality available (also, there are some serious naming issues to discuss). I haven't yet implemented virNodeDevice{Create,Destroy}, nor am I registering for HAL/Devkit events. We don't need this functionality right away, so I may wait 'til next week to implement them. The underlying virNodeDevice infrastructure is ref-counted and accessed via a conn->lock-protected virHashTable (like connections, domains, etc.), so concurrent access shouldn't be a problem. I'll post a patch (with some TODOs ...) on Sunday or Monday morning. Dave On Fri, 2008-09-26 at 14:15 +0100, Daniel P. Berrange wrote:

Hi -
I'm about to start working on host device enumeration, along the (HAL-ish) lines of what was discussed back in April: https://www.redhat.com/archives/libvir-list/2008-April/msg00005.html
I know the xml details haven't been fully fleshed out, but there seems to be agreement that it will be a fairly direct mapping from (a subset of the) HAL info to the details that we need in the xml. Doubtless it will take a while to figure out exactly what subset suffices (and, for that matter, if everything needed is available via HAL ...), but I think the work is well-defined for some of the obvious details (discussed in the above thread) on which there's broad agreement.
Is anyone working on such an implementation?
Did you ever start any work on this project ? The oVirt guys really want this done asap, so if you've not started on it, or have a partial start to work from, I plan to make time to look at it next week
Regards, Daniel
