On the other hand, free software is somewhat easier to support than proprietary software (we have access to the source code, and can make decisions about how to work around old constructs or even see how newer versions changed in relation to older versions - a luxury not available when targetting something where only the interface is public but the source code is hidden). I'm not sure how far back Microsoft supports old versions of Hyper-V, especially given the recent media attention to the fact that they explicitly no longer support Windows XP. Although Hyper-V 2008 is 6 years old, if it is still actively supported (where I could buy a license today and still get support for the product), then libvirt should still consider targetting it. On the other hand, patches speak louder than words - anyone interested enough to actually post a patch, even if it actively excludes an older version of the hypervisor, has more clout than someone like me that has never even used Hyper-V :) So I guess that means it is your call on whether it is easier to drop support for old versions for the sake of making maintenance easier. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
