@@ -4,15 +4,24 @@ 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
-(contained in the optional dependency kqemu). The virtualizer mode
-requires that both the host and guest machine use x86 compatible
-processors.
+qemu-kvm achieves near native performances by leveraging the kvm-kmod
+modules and executing the guest code directly on the host CPU.
+Slackware provides pre-built 32/64 bit x86 kvm-kmod modules or you can
+build different versions with the kvm-kmod package.
+qemu-kvm code has been merged back into qemu since version 1.3.0.
-NOTE:
-qemu builds man-pages at compile-time; to do so, /sbin must be in the
-current $PATH. Be sure to run the script as root ( "su -" ).
+By default, this script builds only the x86 and arm emulation targets
+for qemu; if you prefer to build all supported targets, do this:
-spice is an optional dependency.
+ TARGETS=all ./qemu.SlackBuild
+
+We patch the installed udev rules to require membership in "users"
+group instead of a custom "kvm" group to uses /dev/kvm. If you prefer
+something different, then run the build script like this:
+
+ KVMGROUP=group ./qemu.SlackBuild
+
+Don't forget to load the 'kvm-intel' or 'kvm-amd' module (depending on
+your processor) prior to launching qemu-system-x86_64 with kvm enabled.
+
+spice and usbredir are optional dependencies.
