<p><b>A:</b> QEMU is a generic and open source machine emulator and virtualizer.<br>
When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performances.<br>
When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, and S390 guests.<p>
<p><b>A:</b> Any registered user can submit an application. Use the <a href="../objectManager.php?sClass=application_queue&sTitle=Submit+Application&sAction=add">Submit OS</a> link in the OS DB sidebar to add an entry; it will be processed by an admin before becoming visible to all users. You can make changes to your queued entries by visiting the <a href="../queueditems.php">Your Queued Items</a> page.</p>
<p><b>A:</b> Send those helpful screenshots by clicking on any screenshot image you will see in the specific version page of the application you want to add a screenshot for. If you are not a maintainer, your screenshot will be reviewed and will then be added to the database.</p>
<p><b>A:</b>If you are not a maintainer, you can't create new official How-to's. So the best way to proceed is to post your How-to as a comment in the specific version page of the application of interest. A maintainer might then choose to add your How-to as an official How-to for this database entry.</p>
Simply click on the button you will find in the application overview or specific version page to send your request. An administrator will then review your proposal and add you to the maintainer's team for this application or version. Once we have a community of maintainers, we hope that community will further refine the policies and procedures.</p>
