Subject Re: 4.5.1 - Xen 6.5 SP1 - Live migrations failing - Local disk
Date Wed, 30 Sep 2015 10:31:10 GMT
Hi Koushik,

We see errors such as :

com.cloud.utils.exception.CloudRuntimeException: Failed to send command,
due to Agent:27708, com.cloud.exception.AgentUnavailableException: Resource

However, when I look at the hosts in cloudstack, all hosts are connected
and green, none are reported by cloudstack as being disconnected. So I'm
not really quite sure what is going wrong. As I say, when only one
cloudstack management server is running, everything works perfectly fine.

Cheers
