I have compiled (with initrd) xen 3.3 from source tar ball following the README file under centos 5.2. xen kernel boots fine but my system (2 cores, 2.0 GHZ, 1GB RAM) is slow with a warning message.

***************************************************************

Is my system slow due to this tls warning? or I can ignore the warning.

similar thread is here http://lists.xensource.com/archives/html/xen-users/2006-04/msg00545.html. But thats not working for me. May be I am compiling from source.

Thanks
Paras.
