This error can be caused by a variety of factors, such as an incorrectly specified URI, or a connection that is not configured. SolutionIncorrectly specified URI When specifying qemu://system or qemu://session as a connection URI, virsh attempts https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Host_Configuration_and_Guest_Installation_Guide/App_Hypervisor_Connection_Fail.html to connect to hostnames system or session respectively. This is because virsh recognizes the text after the second forward slash as the host. Use three forward slashes to connect to the local host. For example, specifying qemu:///system instructs virsh connect to the system instance of libvirtd on the local host. When a hostname is specified, the QEMU transport defaults to TLS. This results in certificates. Connection is not configured The URI is correct (for example, qemu[+tls]://server/system) but the certificates are not set up properly on your machine. For information on configuring TLS, see Setting up libvirt for TLS available from the libvirt website. PrevDocument HomeB.2.1. Cannot read CA certificateB.2.2.
