QEMU is a generic and open source machine emulator and virtualizer.
-This is a binary release, repacked for Slackware's package management
-system.
+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.
-It seems the /usr/bin/qemu is hard-coded to look for some files in
-/usr/local/share - there are at least two ways to work around this
-after the package is installed:
- 1. cd /usr/local/share ; ln -s /usr/share/qemu qemu
- 2. replace -s /usr/local/ /usr/./././ /usr/bin/qemu
-
-The first method is the safest, but either should work relatively well.
+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.
