Have a try with (from host)
ldconfig -v -r /vservers/davin

If you don't have libc installed in the guest, none of the standard
binaries will run even if the proper /bin/bash, /bin/ls etc. binaries
are in place. Do you have some statically linked shell handy? sash,
busybox maybe?

Well, comparing /usr/lib on two vastly different systems is usually
pointless. The basic stuff lives in /lib and should look mostly the
same for all systems (with minor differences between distros). Your
system should be able to boot without /usr at all (so that includes
/usr/lib).

For comparison purposes, here's a listing of /lib on one of my
vservers (debian 3.1 basically).
