Does xen 3.0.3-1 still need "mv /lib/tls /lib/tls.disabled"?

Yes it does, unless:
* your /lib/tls is Xen-friendly
* you're running on a 64-bit host (regardless of guest type)
* HVM guests don't need this to be done
* You're running on a non-x86 platform.
RHEL 4 and RHEL 5 now support a bit of "drop a file in /etc/ld.so.conf.d to disable /lib/tls", instead of moving it aside. Moving it aside is fulnerable to update problems, where updating a program with libraries there restores the directory and makes rolling back the Xen installation rather awkward.

Also, I've seen reports that it's not just glibc: db4 drops some libraries in /lib/tls that are problematic for Xen guests.
