Re: [libvirt] Hyper-V driver ?

Hi ! My name ist Michael Sievers. I am studying computer science at Paderborn/Germany. I worked together with Matthias Bolte on a project here at Paderborn, where we evaluated the possibility of controlling Microsoft Hyper-V using WS-Management through libvirt (which is actually called WinRM on Windows). At the end of the project I had a very minimalistic libvirt driver, which was just able to connect to Hyper-V and to power cycle a given VM. Unfortunately, the project stopped at this point and so did my efforts on this topic. Since developing a full fledged Hyper-V driver for libvirt a very time consuming effort I am currently searching for a way to do so which incorporates with my study. At this point I can tell you the following - it is possible to control Hyper-V using libvirt using WS-Management - this is actually the only way (as far as I know) to control Hyper-V from non-Windows hosts, as you can not use WMI (which is Hyper-V main API) from non Windows hosts directly - WS-Management is the bridge to talk to WMI from non-Windows hosts as there are implementations such as OpenWSman which you can use - doing complicated things in WS-Management (e.g. calling a function with reference parameters) is not well documented and that's why a pain to implement The last point was the main reason, why the development stopped after implementing the power cycling. Last week I talked to my professor about this and he told me, that maybe there is a company (unfortunately I can't tell you the name) which is willing to support this effort financially, which would give me to opportunity to resume development. But sadly this not for sure, yet. I will inform you (the libvirt mailing list) during the next two weeks about the results. Cheers Michael Sievers P.S. Sorry for sending this mail three times to libvir-list as I did not remembered that I once subscribed with a different email address. 2010/10/30 Justin Clift <jclift(a)redhat.com&gt;:
