Error Failed To Reconnect To The Hypervisor
From Libvirt Wiki Jump to: navigation, search Contents 1 Failed to connect to the hypervisor 1.1 No connection driver available 1.1.1 Symptom 1.1.2 Cause 1.1.3 Investigation 1.1.4 Solution 1.2 Cannot read CA certificate 1.2.1 Symptom 1.2.2 Investigation 1.2.3 Solution 1.3 Permission denied 1.3.1 Symptom 1.3.2 Investigation 1.3.3 Solution 1.4 Other errors Failed to connect to the hypervisor There are lots of errors that can occur while connecting to the server (when running virsh for example) No connection driver available Symptom When running a command, the following error (or similar) appears: $ virsh -c
to the server (for example, when running virsh). B.2.1. Cannot read CA certificateSymptom When running a command, the following error (or similar) appears: $ virsh -c name_of_uri list error: Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory error: failed to connect to the hypervisorInvestigation The error message is misleading http://wiki.libvirt.org/page/Failed_to_connect_to_the_hypervisor about the actual cause. 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.
