Hi, I know this question has been asked a few times before, but I am not able to connect to my xen hypervisor using a remote uri. Here is how I access it: virsh -c xen://hostname/ list --all Here is the error: libvir: Remote error : server certificate failed validation: The certificate is not trusted. libvir: Remote error : unable to connect to 'domain0.localdomain': Invalid argument Here is the log output: 09:36:17.124: error : remoteCheckCertificate: the client certificate is not trusted. 09:36:17.124: error : remoteCheckCertificate: failed to verify client's certificate 09:36:17.124: error : gnutls_record_recv: A TLS packet with unexpected length was received. I was able to connect using xen+tcp as follows: virsh -c xen+tcp://hostname/ list --all which gives me the expected list of VMs. I am using libvirt version: libvirtd (libvirt) 0.6.3 I created the tls certificates by foll the instrucstions given here: http://libvirt.org/remote.html#Remote_certificates I have a few questions regarding them: 1. While setting up CA, in the ca.info file, what do the options "ca" and "cert_signing_key" mean? 2. While setting up server certificate, in the "server.info" file I added "cn=domain0.localdomain". because output of "virsh hostname" is "domain0.localdomain", I am correct in doing this? 3. In "libvirtd.conf" file, what does the option "listen_addr" exactly mean? Thanks and Regards, Sagar Barve
