Hi, this has to do with security measures on Linux.

First, try to run SheepShaver as root
If it does not work, see here:

Cannot map Low Memory Globals: Permission denied.
Due to a change in how programs in Linux are allowed to use memory, before using SheepShaver you need to set a variable in the file /etc/sysctl.conf. Add this line: vm.mmap_min_addr = 0
and do as root:
echo 0 > /proc/sys/vm/mmap_min_addr
