问ActiveMq启动失败，需要更改hostname，但是腾云主机不能编辑hostname，怎么办？

部署ActiveMQ的时候报错，信息如下：Error creating bean with name 'org.apache.activemq.xbean.XBeanBrokerService#0' defined in class path resource [activemq.xml]: Invocation of init method failed; nested exception is java.net.URISyntaxException: Illegal character in hostname at index 7: ws://VM_0_3_centos:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600 | org.apache.activemq.xbean.XBeanBrokerFactory$1 | main，需要更改云主机的hostname，但是云主机不能编辑Created by cloud-init on instance boot automatically, do not edit，该怎么办？
