Subject Re: Disconnected XenServer 6.5 Master server
Date Tue, 22 Nov 2016 15:15:58 GMT
Hello,

pool master and slaves all is ok. Master new server, and slaves working
with new master. There is perfect.

xe pool-ha-disable
The operation could not be performed because HA is not enabled on the Pool

I restarted cloudstack-management service, but anyway, VM's showing online
and can't be restarted or migrated to another host
