sorry, I used 192.168.223 to replace 192.168.122.65, forget tell you, hosted-engine.ovirt.com=192.168.122.91, it is engine VM, visit hosted-engine.ovirt.com show me web UI. 发自网易邮箱手机版 在2018年04月26日 14:52，Martin Sivak 写道： Hi, > hosted-engine1 : 192.168.122.66 > hosted-engine2 : 192.168.122.223 But you said in an earlier email that: > I hava two node, A:192.168.122.65 , B:192.168.122.66 Make sure your names resolve properly. So far it does exactly what it is supposed to do - when the engine is unreachable, it tries restarting it. Did you really use hosted-engine.ovirt.com as the fqdn? Are you sure it resolves to whatever IP the VM has (192.168.122.91)? Maybe you used /etc/hosts to configure the name on the first host and in the VM, but miss the record on the second host? What does $(host hosted-engine.ovirt.com) show you? > I can not visit web UI, but my engine VM is run, i can login it. engine has > some error > > VdsIdVDSCommandParametersBase:{hostId='1b5f799a-125d-4f4e-8aef-cb2ecdd63136'})' > execution failed: java.net.NoRouteToHostException: No route to host I told you before. This is normal as it is trying to figure out whether the host is up.
