hello To better define the problem I launched the test that fails virnetmessagetest with the option VIR_TEST_DEBUG = 1 and attach the result: # VIR_TEST_DEBUG=1 ./virnetmessagetest TEST: virnetmessagetest 1) Message Header Encode ... libvirt: XML-RPC error : Unable to encode message header FAILED 2) Message Header Decode ... libvirt: XML-RPC error : Unable to decode message length FAILED 3) Message Payload Encode ... libvirt: XML-RPC error : Unable to encode message header FAILED 4) Message Payload Decode ... libvirt: XML-RPC error : Unable to decode message length FAILED 5) Message Payload Stream Encode ... libvirt: XML-RPC error : Unable to encode message header FAILED Is there anyone who can give me a hand to solve the problem? thanks Stefano ---------- Forwarded message ---------- From: Stefano Ricci <sfn.rcc(a)gmail.com&gt; Date: 2014-09-23 19:58 GMT+02:00 Subject: Running the test fails virnetmessagetest with libvirt 1.2.8 To: libvirt-users(a)redhat.com Hello I apologize in advance for my English.

When i tried using the libvirtd running without any problems but I can not run the Connection with the virsh command virsh -c qemu:///system that returns the following error: "Unable to encode message header" and the log shows the error: "virNetSocketReadWire: 1523: End of file while reading dates: Error of input / output". There 's someone who can give me a hand to solve the problem? thanks Stefano
