Hi, How do I turn on tracing in the Xen. I am using xen 3.0.2. I could not find a config option to turn ON tracing. setsize fails with : # setsize 20 Failure to get tbuf info from Xen. Guess size is 0: Invalid argument This may mean that tracing is not enabled in xen. set_size Hypercall failure: Invalid argument May I know how to turn it on? Thanks, Anurag. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Until recently in the -unstable tree, setsize would return weird error messages even if it did what it was supposed to do. Look at the console i/o and see if it says that tracing has been enabled, and try using xentrace. If xentrace works, just ignore the error messages. Presumably the fixes in -unstable will make it into xen 3.0.3. -George On 6/22/06, Anurag Agarwal <anurag_agarwal@symantec.com> wrote:> Hi, > > How do I turn on tracing in the Xen.

At Xen 3.0.2, try tbctl command (0 or 1) Tracing Buffer On and Off (tbctl is in xentrace.) N.B.:This is obsolate command in current change set Thanks, Atsushi SAKAI>Until recently in the -unstable tree, setsize would return weird error >messages even if it did what it was supposed to do.
