Hey Libvirt team. We are looking into issue 14 <https://gitlab.com/libvirt/libvirt/-/issues/14> and issue 90 <https://gitlab.com/libvirt/libvirt/-/issues/90> to make possible contributions to one or both of them. However, before we start preparing patches for either of these issues, we have some clarifying questions about the scope of the necessary changes. Issue 14: Mostly we wanted to know what was wrong with Guannan's previous attempt at patching this. Was it incorrect, incomplete, or otherwise lacking? We also were confused on how Peter's usb-audio commit actually addressed an issue. It seems like most of the changes were documentation and constant and only a few changes changed significant amounts of code. We understand that QEMU is the program actually handling the sound card, but how do Peter's changes actually hook up the sound card with QEMU? Would the changes needed for the usb-net device be the same as Peter's usb-audio changes except in different sections of each file, or would the changes need to be made elsewhere? We saw that Peter and Guannan both had changes to tests/qemuhelptest.c and src/qemu/qemu_capabilities.c (to name a few). Issue 90:In order to implement a new network disk protocol, we believe there should be changes to the parameters in virsh/attach-disk, but we also know that there will likely be changes elsewhere in the codebase to allow support for a new protocol type. Ex: diskSourceNetworkProtocol definitions in docs/schemas/domaincommon.rng. Is there documentation available on what files/sections of the codebase handle supporting network disk protocols, so we can find more reference examples and begin to make changes in the appropriate locations? Thanks in advance, Dustan Helm, Ryan Gahagan, Barrett Schonefeld
