Hi, I'm trying libvirt to connect to Hyper-V servers. It works fine for Hyper-V 2012 servers, however it doesn't work for Hyper-V 2008 R2 (the exact error is | Call to virConnectOpenAuth failed: internal error: Transport error during enumeration: Could not connect (7) (Libvirt::ConnectionError)|.). I'm using the code provided by libvirt documentation (http://libvirt.org/ruby/examples/open_auth.rb) and have authorized basic auth plus unencrypted connection on both 2008 R2 & 2012 servers (http://libvirt.org/drvhyperv.html#auth). Surfing the Internet to find some solutions, I found this (https://www.redhat.com/archives/libvir-list/2014-April/msg00802.html) where a developer talks about stopping 2008 R2 support (because of some technical stuff), while in the documentation (http://libvirt.org/drvhyperv.html) it is explicitely said to be supporting 2008 R2. My question is : does the support has been stopped or does the code to connect to a 2008 R2 server is different from the 2012 server ? I'm using libvirt 1.2.2 and ruby-libvirt 1.2.2. Thanks for your help, Jean-François FILPPI
