[libvirt] Two more libvirt GSOC ideas

Hi, I'd like to add 2 more GSOC ideas to our wiki page, but I'd like to get some opinions whether you think these might even be appropriate GSOC project candidates. #1 PROJECT: Support wildcard with log filters SUMMARY: Enhance the log filters format to allow specifying a wildcard, i.e. <level>:* DESCRIPTION: Currently, libvirt admin interface allows (among other things) runtime tuning of daemon log settings with the exception of setting the global log priority. The main reason for not having an API to get/set the global log priority is that the same effect that setting global log level would have can be achieved with using log filters only which in terms of logging control provide us with more granularity. However, in order to achieve the same effect using filters only, one would end up with a filter similar to this: 1:access 1:daemon 1:conf 1:cpu 1:libvirt 1:locking 1:logging 1:network 1:nwfilter 1:util Therefore, we should enhance the format of a filter to allow us to simply use the following instead: 1:* other_filters #2 PROJECT: Extend node device driver's API set SUMMARY: Modify the existing set (adjust/add) of APIs for node device driver in order to provide similar functionality (conceptually) to other drivers. DESCRIPTION: The node device driver is responsible for host device management. In most cases, this means that we're simply just report device's capabilities and track its lifetime. This is enough for physical host devices, however, there are a few other virtualization features like NFV, NPIV, and MDEV where libvirt should also be able to create such virtual devices. Currently, libvirt is only able to create transient (temporary config) NPIV/vHBA devices, so besides having support for creating virtual functions and mediated devices on feature-capable physical device we also need to be able to store persistent configuration of such virtual devices. Besides extending the existing set of APIs, this will also require a certain amount of refactor of our current code base. Not all of the changes mentioned above are absolutely necessary to finish the project successfully. Thanks, Erik
