Subject 答复: Cloudstack-agent gets the local IP address exception
Date Tue, 23 Apr 2019 14:48:44 GMT
Hi Andrija



      Your method is very good. I just tested agent. lb. When management fails, the agent
can complete switching in a very short time.

Hi Jerry,

not a good idea, if you don't mind me saying that.

Are you using 4.11 release ? If so you should use the internal LB logic
that is now part of Agent on KVM side - please check this one:

Let me know if this works for you.

Best,
Andrija
