QEMU is a generic and open source machine emulator and virtualizer. 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. When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. A host driver called the QEMU accelerator (also known as KQEMU) is needed in this case. The virtualizer mode requires that both the host and guest machine use x86 compatible processors. The supported host and target CPUs are listed in the status page.

List of Supported Guest OSes
Target CPU support
The target CPU is the one QEMU emulates. User emulation means emulation of user code in order to launch Linux processes. System emulation means full CPU emulation in order to launch an Operating System.
Target CPU User emulation System emulation
x86 OK OK
x86_64 Not supported OK
ARM OK OK
SPARC OK OK
SPARC64 Dev only Dev only
PowerPC OK OK
PowerPC64 Not supported Dev only
MIPS OK OK
m68k Dev only Dev only
SH-4 Dev only Dev only
Host CPU support
The host CPU is the one which executes QEMU.
Host CPU Status
x86 OK
x86_64 OK
PowerPC OK
Alpha Testing
Sparc32 Testing
ARM Testing
S390 Testing
Sparc64 Dev only
ia64 Dev only
m68k Dev only
Note: Testing means that the emulator is working on most of the regression tests, but that some important application fail. |
