[libvirt] [hyperv]: Connection failure

Hi Everyone, I installed a HyperV server and trying to connect to it using libvirt. As suggested by libvirt driver wiki (http://libvirt.org/drvhyperv.html), I've enabled Basic authentication on the server (and also enabled HTTP connection request for debugging purpose). Even after all this configuration, on connection I get error as: ---------------Enter Administrator's password for 10.y.y.y: xxxxxx 2013-02-14 00:02:25.122+0000: 6825: info : libvirt version: 1.0.2 2013-02-14 00:02:25.122+0000: 6825: error : hypervDebugHandler:1444 : openwsman error: NULL response libvir: Hyper-V Driver error : internal error Transport error during enumeration: Could not connect (7) Failed to open connection libvir: error : invalid connection pointer in virConnectGetHostname Host name: (null) libvir: error : invalid connection pointer in virConnectClose ------------------------------ Hyper-V server configuration looks like:xxx> winrm get winrm/config/serviceServiceROOTSDDL = <long string>MaxConnectionOperations = 4294967295MaxConnectionOperationsPerUser = 1500MaxConnectionTimeoutms = 240000MaxConnections = 300MaxPacketRetrievalTimeSeconds = 120AllowUnencrypted = trueAuth Basic = true ........AllowRemoteAccess = true ------------------------------ I'm have libvirt on ubuntu (3.2.0-37-generic) and openwsman is 2.2.3-oubuntu4 version. Also, I'm using "Administrator" credentials to connect to HyperV server. Please suggest what is missing from my setup. Thanks!Ata
