Hi,
I am runnign a debian etch system with the packaged xen3.0.3 and the
patched kernel for the source distrib (2.6.16.29). I try both pae and
none pae modes on my 4G dual athlon. But in all cases I un into problems
in the domu. I see segfaults in what seem to be tls libraries but not in
/lib/tls/ (/lib/libnsl.so.1 to be exact). I have installed libc6-xen and
moved /lib/tls out of the way.
My question is then, why isn't the emulation mode activted? I would not
mind a slowdown for the occasionnal call to that library rather than the
segfault....

PS: bcfg2 is what I use to trigger it:
> strace bcfg2 -vvvv -d
