[I am not very familiar this 32bit vs 64bit stuff...]
There is an xen server with four AMD Dual-Core Opteron(tm) 8220 CPUs,
I installed debian lenny on it and uname shows:
Linux xenserver 2.6.26-2-xen-amd64 #1 SMP Sun Jun 21 08:09:04 UTC 2009 x86_64 GNU/Linux

Then I create a domU with xen-tools with "arch=i386" option, however,
this domU still uses 2.6.26-2-xen-amd64 kernel (I guess it is a kind of compatible mode...?): Linux linserver 2.6.26-2-xen-amd64 #1 SMP Sun Jun 21 08:09:04 UTC 2009 x86_64 GNU/Linux

The problem is that I installed matlab in the domU
and starting the license server failed with
"Error: No FLEXnet License Manager binaries for glnxa64"

Then I made a symlink glnx86 -> glnxa64, and flexnet started without any problem, however, there is a lot of glnx86 directory in the installed tree... So the question is, that must I really create such symlinks (because the faulty detection of the arch) or is there an other way that makes such auxiliary programs to detect i386 "arch" in the domU...?

(One more thing: the installed tree is rsync-ed from an other i386 machine, but I guess that if I made a fresh install the installer would create glnxa64 dirs with 64bit files which would be wrong, wouldn't it?)
