           Summary: mv /lib/tls confusion
           Product: Xen
           Version: unstable
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Unspecified
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: stevenwagner@xxxxxxxxx


Xen HowTo's all over the web say to do:

mv /lib/tls /lib/tls.disabled

And everyone has the idea that if you don't do this you will have reduced
performance. If you simply mv tls, then your performance is fine.

BUT

http://bits.xensource.com/Xen/docs/xen3_rpm_install_notes.html

Clearly states.

"Xen kernels do run correctly using the native glibc, but performance is
significantly impaired. If you don't want to install the Xen-friendly glibc, a
(poor) alternative is to disable the thread-local storage (tls) handling
features of glibc by hiding them, for example

mv /lib/tls /lib/tls.disabled

Who is correct?
