In /var/log/messages you see that there may be some problems with the XenStore Daemon (xenstored) of the Oracle VM or Xen Server.
In some cases it will be useful to have a debug trace of XenStore daemon for its operation.
Solution
On the OracleVM Server:
- Edit /root/.bashrc
- Add line
export XENSTORED_TRACE=1 - Reboot the OracleVM server
- The traces will be written into:
- /var/log/xen/xenstored-trace.log
