On Oracle VM, in some testing and/or development environments, the Oracle VM Servers are getting their IP addresses assigned dynamically, e.g. using DHCP.
After a server reboot, the server is being reported by the Oracle VM manager as offline and attempting to re-discover it fails with the following kind of error message :
OVMAPI_4010E Attempt to send command: discover_hardware to server: ovs1 failed. OVMAPI_4004E Sync command failed on server: 10.172.219.10. Command: discover_hardware, Server error: org.apache.xmlrpc.XmlRpcException: I/O error while communicating with HTTP server: Connection refused [Tue Jul 28 09:31:21 CEST 2015] [Tue Jul 28 09:31:21 CEST 2015]
The issue doesn't reproduce after each reboot, it appears to be happening randomly, more often when the OVS server has been powered off for a long time.
Reboot of the server.
