Hi,

I’m using qemu+ssh://username@hostname/system as the remote URI. Libvirt seems to be communicating fine until some 2 minutes (we poll every 5 seconds) and then it throws up RPC error and many counters are wrong. But if I collect on localhost the counters seems to be coming fine. Test and testvm are guests on the local machine where as Win8 and Ubuntu* are remote URI’s connected through ssh.

What causes this error “libvir: RPC error : End of file while reading data: : Input/output error”

and how do we fix it ?                                                                                                    

I’ve pasted the logfile inline.

Localhost from which we are connecting:
