But it seems there are still some problems to solve before I can successfully creat it. I first cloned Julien's arndale-domU-3.9 branch which mentioned in wiki. Then I modified gic addresses xenvm-4.2.dts to meet OMAP5432 requirement: --- a/arch/arm/boot/dts/xenvm-4.2.dts +++ b/arch/arm/boot/dts/xenvm-4.2.dts @@ -49,13 +49,13 @@ reg = <0 0x80000000 0 0x08000000>; }; - gic: interrupt-controller@2c001000 { + gic: interrupt-controller@48211000 { compatible = "arm,cortex-a15-gic", "arm,cortex-a9-gic"; #interrupt-cells = <3>; #address-cells = <0>; interrupt-controller; - reg = <0 0x10481000 0 0x1000>, - <0 0x10482000 0 0x100>; + reg = <0 0x48211000 0 0x1000>, + <0 0x48212000 0 0x1000>; }; timer { And make the kernel image as wiki said: $ cat arch/arm/boot/zImage arch/arm/boot/xenvm-4.2.dtb > image Write a config file used by xl like: kernel = "/root/domU/image" memory = "128" name = "domU" vcpus = 1 disk = [ 'phy:/dev/loop0,xvda,w' ] Setup loop device: $ losetup /dev/loop0 /root/domU/xen-arm.img which xen-arm.img is the a bootable rootfs.
