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 > But still getting these error message in domU log file and also on > console when access it via console which makes domU console unusable. 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) Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=| -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
