Hello all,

After compiling xen on a debian testing
mv /lib/tls /lib/tls.disabled

and in a domU I installed kde, openoffice, mozilla, etc.
Performance is not what I expected so I compiled a xen-friendly libc6

-----I copied this from the xen-users list------
Debian's current glibc-2.3.5-6 seems to have included this patch already.
apt-get build-dep libc6
apt-get source libc6

edit debian/rules adding
'-mno-tls-direct-seg-refs' to BUILD_CFLAGS y HOST_CFLAGS.

dpkg-buildpackage -rfakeroot
-------thanks-----------
after installing libc6_2.3.5-13_i386.deb I don't get that warning anymore :)

but performance hasn't noticeably improved.

How can I test this?
Thanks.
Chris.
