My domains are booting and working fine. Only while domU or dom0 are booting, I get this message for DomU: *************************************************************** *************************************************************** ** 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: nash (pid=834) ** *************************************************************** *************************************************************** In dom0, the offending process is hotplug. I already have moved /lib/tls to /lib/tls.disabled! How can I get rid off this message? Thanks for help.

Could you please post the result of:
find / -noleaf -type d -name "*tls*"
from dom0 amd domU and also:
ldd /sbin/mkinitrd
from dom0.

OK ... tls has been moved on both systems.
I never had any problems on domU or dom0 since I moved tls on my
FC3 dom0 with a FC4 domU and I just ignore the message
I guess, that you will get the same ldd result if you run:
[root@tivoli Kernel]# ldd /sbin/nash
not a dynamic executable
[root@tivoli Kernel]# ldd /sbin/hotplug
not a dynamic executable
Maybe you have seen the answer from Ernst Bachmann in the other
thread ... I also think, that this is not a problem ... it is just
annoying:

You can search in the mailing list archive:
http://lists.xensource.com/archives/html/xen-users/
with the words "fedora", "glibc" and "tls". There
was
a discussion about recompiling the glibc without tls
support and other usefull information about this
"problem" ... but I also think, that you don''t have to
do anything.
I''m running a lot of different programms in my domU
test environment:
- Oracle
- DB2
- "IBM Tivoli Systems Management" software
- apache
- mysql
- a lot of other stuff
Everything works fine :))
