How to Enable XenStore Tracing for Xen / OracleVM?

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:

1. Edit /root/.bashrc
2. Add line 
        export XENSTORED_TRACE=1


3. Reboot the OracleVM server
4. The traces will be written into:

• /var/log/xen/xenstored-trace.log
