KVM virtualization with Qemu and Aqemu
Converting
Aqemu supports converting existing images to other formats. Open the Convert HDD Image dialog in the File menu and select the source file (Figure 4). Then enter a name for the new file and use the Format field to define the software for which the image is intended. You can use this method to create an image for VirtualBox (Figure 5).
Figure 4: You can convert an image to an alternative virtualization format.
Figure 5: An image converted via Aqemu runs smoothly in VirtualBox.
After you click on Convert, the software gets to work. Bear in mind that, regardless of the file, you need to add the appropriate extension to the filename, so that other virtual environments will accept the file.
On Record
Like other virtual environments, Aqemu offers a log feature. Logs are found in the VM menu in the main window. View the log using Show QEMU Error Log Window, or display the parameters of the currently selected VM using Show QEMU Arguments.
Conclusions
The KVM/Qemu/Aqemu trio easily outpaces VirtualBox on desktop systems. Thanks to the graphical interface, Aqemu is suited to end users who do not want to spend hours learning the command-line parameters in order to leverage the options of KVM/Qemu.
KVM/Qemu is much more flexible than VirtualBox, and it supports alternative hardware architectures such as ARM and Sparc in addition to Intel. KVM/Qemu also offers significantly improved performance on guest systems by reducing the overhead.
