Xen users - Mar 2009 - How to disable tls on CentOS 5 with Xen 3.3.1?

Hi:

I downloaded Xen 3.3.1 source from xen.org, compiled and installed it on CentOS
5. At first boot into xen, I got an error message about tls and told me to use
"mv /lib/tls /lib/tls.disabled" to disable it. I issued that command
after the first boot. And also tried to remove that directory to /root.

But after that, I still got the same error message about tls  when booting into
Xen. The offending process is "modprobe".
I tried to reinstall xen using "sh  ./dist/install.sh" and rebuild
ramdisk using "mkinitrd" command. But that error remains. And the
system is very slow.

How to disable the tls? Should I use "make world" again?

BTW: I am running the CentOS in a VMware workstation virtual machine. So the Xen
is on top of vmware workstation. I am not sure whether it matters. But I can run
Xen3.0.3 coming with CentOS without the tls problem. I want to compile Xen 3.3.1
because I want to enable some debug options and test the newest stable version
of Xen.

Regards,

Jiang

The suggestion does nothing on CentOS because that directory is empty.  
Put this in /etc/ld.conf.so.d/xen.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

Note that the file name _must_ end ".conf".   When you''ve
done that, run
/sbin/ldconfig and reboot.  The problem should go away.

It works. Thank you very much.

Just to clarify, the path for xen.conf should be /etc/ld.so.conf.d/xen.conf
