nova-compute中出现日志
热迁移报错，libvirt中qemu+tcp的方式无法连接，解决方案如下：
计算节点执行
# vim /etc/libvirt/libvirtd.conf
listen_tls = 0
listen_tcp = 1
unix_sock_group = "root"
unix_sock_rw_perms = "0777"
auth_unix_ro = "none"
auth_unix_rw = "none"
log_filters="2:qemu_monitor_json 2:qemu_driver"
log_outputs="2:file:/var/log/libvirt/libvirtd.log"
tcp_port = "16509"
listen_addr = "0.0.0.0"
auth_tcp = "none"
/etc/sysconfig/libvirtd中 #LIBVIRTD_ARGS="--listen" 参数打开
重启libvirtd服务，再次进行迁移
成功解决
