None of these problems have anything to do with qemu. They are problems with
your root FS. Qemu works exactly the same way as a real Arm machine.
The arm_test image on the qemu website is a minimal cut-down test/demo system.
It is not not intended to be a full general purpose linux system. Sounds like
you need to get yourself a proper linux install. The Debian installers work
pretty much out the box.
If you already are using a different linux distro, you need to contact whoever
supplied it.
