[vmcuser@rhel60h207kvm .ssh]$ virsh -c qemu+ssh:// vmcuser@9.10.110.241/system list --all error: authentication failed: Authorization requires authentication but no agent is available. error: failed to connect to the hypervisor Here is my settings different from default: [root@rhel60e201c libvirt]# diff libvirtd.conf libvirtd.conf.old 81c81 < unix_sock_group = "vmcuser" ---

#unix_sock_group = "libvirt" 88c88 < unix_sock_ro_perms = "0777"

#unix_sock_ro_perms = "0777" 98c98 < unix_sock_rw_perms = "0770"

#unix_sock_rw_perms = "0770" 129c129 < auth_unix_ro = "none"

#auth_unix_ro = "none"
