I'm less than 100% sure myself. :-) Most likely you simply configure xenguest_arm64_defconfig, build the configuration and the package would be the copyright plus one output file. In order to use this you setup a VM/domain configuration file where the single output file is specified as the "kernel" parameter. This would cause the U-Boot image to be loaded as if it was an OS kernel and be loaded into the resultant VM and started. Then in theory U-Boot loads configuration parameters from VM disk devices as it normally would. -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sig...@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445
