In my case upgrading device-mapper-libs solved the issue: yum upgrade device-mapper-libs In my case, some hints were given by checking status of libvirtd: service libvirtd status There were errors like below, Do not pass the --listen parameter. Section A.18.3, “The Guest Virtual Machine Cannot be Started: internal error guest CPU is not compatible with host CPU” Failed to create domain from vm.xml error: monitor socket did not show up.: This is because to communicate with the destination libvirtd, the source libvirtd may need to use network infrastructure different from that which virsh (possibly running on a separate machine) requires. ⁠Solution

The problems here are that libvirt hard codes the locations for qemu libvirt doesn't tell you why the connection fails fixing the first might make this problem go away.

  1. If this is not desirable (because of firewall configuration, for example), the port number can be specified in this command: # virsh migrate qemu qemu+tcp:// tcp:// Another option is to use

  3. Cannot read CA certificate Symptom When running a command, the following error (or similar) appears: $ virsh -c list error: Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory
  4. This delay allows the bridge time to watch traffic from the interface and determine the MAC addresses behind it, and prevent forwarding loops in the network topology.
  5. To determine if this is the cause, run virsh net-start default from a root shell to start the default virtual network.
  6. However, the guest can start successfully using the QEMU command directly.
