Symptoms

  1. The following errors are being reported every few minutes in the Cloud Infrastructure Log:

    18766   Nov-10-2015 00:10:02    The virtual machine or the source and destination servers do not comply with the migration requirements.                        Failed

18765   Nov-10-2015 00:10:01    The selected object was opened for editing incorrectly. Try to open the object again or contact your Parallels Server administrator for assistance.

  2. Additional errors could be found on PACI Instance Manager node in /var/log/IM/PACI-vm2vf.log:

Cause

Operation of copy OS Template to other virtualization node fails because of lack of diskspace in /vz partition on destination node.

Resolution

  1. Find corresponding error in /var/log/IM/PACI-vm2vf.log on PACI IM node. For example:

    2015-11-10 13:25:49,118 () DEBUG ReqIdSetter [RequestProcessor-24942] - Received CORBA request: #2589582 - copy_template_cb
2016-11-00 13:25:49,118 (e40fd12b-7f1c-40f7-916c-2a39172f9549) INFO  LoggingProxy [RequestProcessor-24942] - invoked: register_callback(
  <Vm2VfCallback>
); reqId=1026052; corbaReqId=2589582.
2016-03-30 21:46:49,118 () INFO  LoggingProxy [RequestProcessor-24942] - invoked: copy_template_cb(
  "10.39.87.217",
  "root",
  <hidden>,
  "10.39.87.218",
  "root",
  <hidden>,
  "windows-server-2008-x86_64",
  null,
  java.nio.DirectByteBuffer[pos=0 lim=32 cap=32]
); reqId=1026052; corbaReqId=2589582.

    In the first section of the logs you can see the source and destination servers which are being used the syntax is as following:

    copy_template_cb(
  "Source_Server_IP_Address",
  "Source_server_User_Name",
  <hidden>,
  "Destination_Server_IP_Address",
  "Destination_Server_User_Name",
  <hidden>,
  "Template_Name",
  null,
  java.nio.DirectByteBuffer[pos=0 lim=32 cap=32]
);

  2. After gathering the Source and destination server address, log into the source node and check location and size of corresponding template:

    [root@node1 ~]# prlctl list -t
UUID                                    DIST            T  NAME
{9d23b523-a799-4305-8138-7e5b675480fd}  win-2008        VM windows-server-2008-x86_64
[root@pcs5 ~]# du -sh /var/parallels/windows-server-2008-x86_64.pvm/
19G     /var/parallels/windows-server-2008-x86_64.pvm/

  3. Check available disk space on destination node:

    [root@node2 ~]# df -h /var/parallels/
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_pcs2-lv_root
                       24G   17G  5.7G  75% /
  4. In-order to fix this error message increase the disk space of the /vz partition on the destination server.
