 Can you paste the output please?

Not a problem, here you go:

# This directive teaches ldconfig to search in nosegneg subdirectories
# and cache the DSOs there with extra bit 1 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

cheers,
Chris

Bug#514962: strings-static in chkrootkit triggers false Xen /lib/tls warning

2009-02-12 Thread Chris Samuel 
Package: chkrootkit
Version: 0.48-8
Severity: minor


Running Lenny in a Xen VM at Rimuhosting.com the strings-static
program from chkrootkit triggers the following warning that can
be seen in dmesg.


  ***
  ***
  ** 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: strings-static (pid=7880)  **
  ***
  ***

Continuing...

However this is misleading as the libc6-xen libraries are 
already installed and there is no /lib/tls directory, viz:

csamuel:~# ls /lib/tls
ls: cannot access /lib/tls: No such file or directory
