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

Is there anyone who can give me a hand to solve the problem?


I must say I have only slightest idea what might cause it.  What
library are you using for xdr (or what's your libc)?  Are you getting
this with pure glibc?  I can't think of anything than non-standard
libc causing this.  Although we have people running libvirt with
uClibc, libtirpc, etc. and all works well.

Hello
I apologize in advance for my English.
I compiled the new version of libvirt 1.2.8 on an environment Development

The compilation finishes without any problems but in the execution of the
tests fails virnetmessagetest.
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
