I struggled with below issue for a while and playing with multiple tools avaialble on web to check if wsman was working, I found that issue was with libopenwsman version available for ubuntu. I switched the testbed to SL 6.1, installed libvirt on it and providing necessary openwsman libraries. I can perform basic set of operations. -AFrom: ata.husain(a)hotmail.com To: libvir-list(a)redhat.com Date: Wed, 13 Feb 2013 16:15:53 -0800 Subject: [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/service Service ROOTSDDL = <long string> MaxConnectionOperations = 4294967295 MaxConnectionOperationsPerUser = 1500 MaxConnectionTimeoutms = 240000 MaxConnections = 300 MaxPacketRetrievalTimeSeconds = 120 AllowUnencrypted = true Auth Basic = true ..... . . .

Also, I'm using "Administrator" credentials to connect to HyperV server. Please suggest what is missing from my setup. Thanks!
