Actually i've realized its not the name of the config name which matters.
The issue is you need to run 'ldconfig' after creating the config file so
that it updates its library cache

  echo "hwcap 0 nosegneg" > /etc/ld.conf.so.d/nosegneg.conf
  ldconfig

Right, I did this and run 'ldconfig' afterward but  its /etc/ld.so.conf.d/nosegneg.conf not /etc/ld.conf.so.d/nosegneg.conf , may be typo

Once you've done that, you can verify the linker knows about Xen variant
by looking for libc mapping. eg before I add the hwcap stuff it shows:

  # ldconfig -v -p 2>&1 | grep libc.so
        libc.so.6 (libc6, OS ABI: Linux 2.6.9) => /lib/libc.so.6

I get this before echo thing...

ldconfig -v -p 2>&1 | grep libc.so
        libc.so.6 (libc6, OS ABI: Linux 2.6.9) => /lib/libc.so.6

Once I create the hwcap setting & re-run ldconfig it shows

  # ldconfig -v -p 2>&1 | grep libc.so
        libc.so.6 (libc6, hwcap: 0x0018000000000000, OS ABI: Linux 2.6.9) => /lib/i686/nosegneg/libc.so.6
        libc.so.6 (libc6, OS ABI: Linux 2.6.9) => /lib/libc.so.6

After hwcap I get ..

ldconfig -v -p 2>&1 | grep libc.so
        libc.so.6 (libc6, hwcap: 0x0018000000000000, OS ABI: Linux 2.6.9) => /lib/i686/nosegneg/libc.so.6
        libc.so.6 (libc6, OS ABI: Linux 2.6.9) => /lib/libc.so.6

But still getting those  '4gb seg fixup, process' errors

ldconfig is enough not need to reboot the guest right?

Thanks. Askar

Dan.
