Has anyone properly tested the RHEL and CentOS 5 glibc in clients? I'm forced to use the xensource 3.1.0 kernel-xen kernel to get RHEL 4 DomU's, and it causes the guests to whine bitterly at boot time about the /lib/tls issues. Xensource used to publish a modified glibc for RHEL 4.4 to avoid the /lib/tls emulation issues, but CentOS and RHEL 4.5 have an even more recent glibc.

What kernel do you use in the guests? The RedHat/CentOS provided kernels properly place glibc hint files into /etc/ld.so.conf.d/, which makes glibc use the nosegneg variants available in RHEL/CentOS 4.5 and 5.

If you use Xensource kernels, I guess those don't create the files correctly.
Apparently not! I'll try some domains with such a kernelcap file and see how they do.
