I have created some KVM Virtual Machines, each running Ubuntu 11.10 and using 1 CPU and 1024MB of RAM. I wonder how portables are those images. I mean if I copy the Image files to another computer (with different hardware than the Original Host) will they work?

Yes it will work. The alternative way (If using Ubuntu) is the easiest way to do the same.

You can convert the .img image (row) to .qcow2 format.

For converting .img to .qcow2 need to use command qemu-convert

Please read the man page of qemu command for more details.

The .img images are row format so it is taking much more space then .qcow2.
