Hello

> 1. How do I build my own .img file to boot?

Simply use qemu-img to create one. There are many file types you can 
use, raw, cow,qcow and etc.

After that, simply start qemu with this new blank image together with 
your favourite distro ISO image (pass the path and the filename to 
-cdrom) and install like usual. The installation procedure is 100% 
similar like installing Linux to real hard disk on real PC.

> 2. Can I run multiple qemu sessions ( so I can run clustered oracle
> )?

yes you can. Simply run multiple qemu instance. Just remember to pass 
distinct MAC address  number to each qemu instance. To save time so you 
don't need to build or copy multiple disk image, just use COW image 
file based on one raw disk image. 

You probably need to learn how to use VDE so you can build virtual 
network among qemu instance. 

read my HOWTO  (qemu+openSSI HOWTO) on qemu.dad-answers.com "HOWTO" 
section on steps to create virtual openSSI cluster using qemu. You can 
adapt it on any other type of cluster.

hope it helps.

regards,

Mulyadi
