hwcap 0 nosegneg
That's the one for that kernel: in layman's terms, it tells ldconfig to
look in /lib, not in /lib/tls.

And that's the one for the Centosplus kernel.

I looked at that thread, however not clear on how i can compile it.
Are there are more detailed howto or something which i can refer ?
You'd edit the .spec file from the SRPM for glibc, recompile it with the
modified configure statement, and install the new RPM's. Are you
comfortable with rebuilding RPM's?
Also we are not installing compiled xen 3.1.1 on top of centos xen
packages. I had specifically removed all centos xen packages, and then
installed xen 3.1.1. Inside dom0, i have no issues, only the domU is
giving the /lib/tls error.
Right. The Xen kernel and glibc are reporting that it will look in
/lib/tls for libraries, and reporting that you will suffer a serious
performance penalty for any functions using those libraries. There are
similar libraries in /lib, which should be used instead in a Xen guest.
