By using dynamic translation, it achieves very good performance. </p><p>When used as a virtualizer, QEMU achieves near native performance 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, 64-bit POWER, S390, 32-bit and 64-bit ARM, and MIPS guests. </p><p>QEMU is a member of <a rel="nofollow" class="external text" href="https://www.qemu.org/conservancy/">Software Freedom Conservancy</a>. </p><p>QEMU releases can be downloaded here: <a rel="nofollow" class="external free" href="https://www.qemu.org/download/">https://www.qemu.org/download/</a> </p> <h2><span class="mw-headline" id="Creating_Accounts">Creating Accounts</span></h2> <p>To help control spam, we have disabled account creation on this wiki.
