Ubuntu Jaunty Jackalope running in QEMU
First, install the package qemu:
apt-get install qemu
Next, we will need to create a QEMU image, so use the following command (and adjust parameters if needed to):
qemu-img create -f qcow qemu_disk.img 3G
The qcow (QEMU Copy-on-Write) specifies the disk image type, while the 3G parameter specifies the amount of memory that can be used (3 GB in this case).
Given that we have an ISO distro image, in order to start it in QEMU use, for example:
qemu -cdrom distribution_image.iso -hda qemu_disk.img -m 256 -boot d
-cdrom distribution_image.iso chooses the ISO image which should be loaded
-m 256 switch sets the virtual RAM size to 256 MB, default being 128
-boot d specifies to boot on CD-ROM, default being c, hard-disk
Below is a screenshot showing Ubuntu 9.04 Jaunty Jackalope running in QEMU on Debian Lenny, after giving the command (one line):
qemu -cdrom ubuntu-9.04-desktop-i386.iso -hda qemu_disk.img -m 256 -boot d

I had troubles running Jaunty installer inside Qemu virtual machine.
The edit boxes just don't get keyboard focus on clicking on them.
Have you expirienced such troubles?
Qemu is really a great tool to try Linux or BSD distributions, without having to reboot your PC.
But the most notable feature of Qemu is its ability to emulate other architectures. So, you can run a Linux PPC distribution from your x86 computer. This can be really interesting for embedded or cross-platform software development.
"Why to prefer this to for example "Virtualbox".. ?"
Ummm... because VirtualBox requires admin rights? This doesn't.
When booting arch in qemu, It gets to this stage and stops:
trying to set up timer as virtual wire IRQ
Also, in the terminal, i get this message:
Could not open '/dev/kqemu' - QEMU acceleration layer not activated: No such file or directory
What is the problem????
Install QEMU accelarator. It will solve your problem.
