There are failed tasks for VE backups in customer CP.

The tasks fail with timeout with no callback received from vm2vf daemon. In /var/log/IM/PACI-im.log the following error is found:

2015-11-23 15:21:19,589 () ERROR Vm2VfProviderBase [VM2VF callbacks watchdog thread] - No registered callback found: ActiveCallbackId [timestamp=2015-11-22 23:21:19.484, reqId=162737, corbaReqId=927068, info=backup ve [{246853d3-b2e6-4758-afb1-150bbcb3bc9c}] to the node [], contextId=(95fd9507-9dd8-4ede-9502-631beafb9c85)]

In case of OA 7.0 the error is:

2016-11-21 16:11:18,054 (330f4970-6848-4b69-bed1-3d66704108c4) ERROR GenericVm2VfTask [Shared executor thread #7 @1 @INTERACTIVE] - timeout()

In /var/log/IM/PACI-vm2vf.log at the same time it is clear that the backup task is still in progress:

The backup operation lasts longer than the task timeout.


To solve the issue, find out if it is expected that the backup task lasts so long. Normal rate is 1 hour for a 100GB virtual machine.

If the VM is indeed huge and requires more than 4 hours to be completed, edit the task timeout in /usr/local/share/PACI-im/IM-config.xml:


<vm2vf callback-timeout-min="240" log="true" mode="remote">


<vm2vf callback-timeout-min="720 log="true" mode="remote">

Important: For OA = 7.0 this parameter is discarded, and it is needed to user ms value instead (this is fixed in 7.1):


<vm2vf callback-timeout-ms="14400000" log="true" mode="on-node">


<vm2vf callback-timeout-ms="21600000" log="true" mode="on-node">
