I've drafted a test plan for Hyper-V support for areas to be tested: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Hyper-V+Test+Plan+for+4.3 based on the FS (https://cwiki.apache.org/confluence/x/4hLVAQ). Test cases are being drafted (not many new tests really, mostly consolidating existing tests to be run on new hypervisor) and will be uploaded in the next few days. Meanwhile, any feedback/comments are welcome!
Thanks, Sowmya
