Hi All,

Ok I've overcome all obstacles so far and have xen booting as dom0 in
slackware. :-)

Now the one thing I haven't been able to solve yet:

At boot, xen warns that I need to disable tls:

***************************************************************
  ***************************************************************
  ** WARNING: Currently emulating unsupported memory accesses  **
  **          in /lib/tls glibc libraries. The emulation is    **
  **          slow. To ensure full performance you should      **
  **          install a 'xen-friendly' (nosegneg) version of   **
  **          the library, or disable tls support by executing **
  **          the following as root:                           **
  **          mv /lib/tls /lib/tls.disabled                    **
  ** Offending process: init (pid=1)                           **
  ***************************************************************
  ***************************************************************

^^^ I run slackware and there IS NO /lib/tls....

I have read extensive list entries forum posts etc regarding this and
still haven't resolved it....

Here's what I've done:

Downloaded the slackbuild for glibc2.5 which matches my current version.

Changed the glibc.SlackBuild like so:

CFLAGS="-g $OPTIMIZ -mno-tls-direct-seg-refs" \
../configure \
  --prefix=/usr \
  --enable-kernel=2.6.16 \
  --with-headers=/usr/src/linux-${KERNEL_HEADERS}/include \
  --enable-add-ons=libidn,nptl \
  --enable-profile \
  --infodir=/usr/info \
  --mandir=/usr/man \
  --with-tls \
  --with-__thread \
  --without-cvs \
  $TARGET-slackware-linux

Then built the package and installed it.

Rebooted and rebuilt xen dom0

Rebooted to xen dom0 kernel and....

I STILL get the tls warning....(I am not using initrd image)


grrrrr....

Any help?

thanks

M
