4gb seg fixup, process on FC6 domU

I9;ve done all of that without success. Any other ideas?

I&#39;ve renamed /lib/tls to /lib/tls.disabled and echo 'hwcap 0 nosegneg&#39; >
/etc/ld.so.conf.d/libc6-xen.conf

But still getting these error message in domU log file and also on console when access it via console which makes domU console unusable.

Any help in this regards, will be greatly appreciated.

Thanks. Askar

Both of those are redundant/wrong for FC6.

First, there is no separate /lib/tls anymore - FC6 ditched
old pthreads
implementation, and the new NPTL is the default in /lib. So
renaming the
empty /lib/tls directory is irrelevant.

Second, the 'hwcap 0 nosegneg' stuff is automatically
installed by the
Xen kernel RPM, eg

  $ rpm -qf
/etc/ld.so.conf.d/kernelcap-2.6.18-1.2868.fc6.conf
  kernel-xen-2.6.18-1.2868.fc6

  $ cat /etc/ld.so.conf.d/kernelcap-2.6.18-1.2868.fc6.conf 
  # This directive teaches ldconfig to search in nosegneg
subdirectories
  # and cache the DSOs there with extra bit 0 set in their
hwcap match
  # fields.  In Xen guest kernels, the vDSO tells the
dynamic linker to
  # search in nosegneg subdirectories and to match this
extra hwcap bit
  # in the ld.so.cache file.
  hwcap 0 nosegneg

What kernel version are you running & what kernel-xen
& libc RPMs are 
installed in your guest showing this problem. Also are they
successfully
(eg, rpm -V kernel-xen  libc)
