I’ll try now to hook that into the code as you suggest.
OK I’m still doing something wrong here because my kernels are not booting on
EC2. Any clues as to what I could try next?
Here is an extract from my callmain.c
#include <bmk-core/platform.h>
#include <bmk-core/printf.h>
static char hardcoded_jsoncfg[] = "{\"cmdline\": \"simple_baked.xen\", \"net\":
{\"cloner\": \"true\", \"type\": \"inet\", \"method\": \"dhcp\", \"if\":
\"xenif0\"}}";
static char *
jsonordie(void)
{
I then do:
(from rumprun directory)
build-rr.sh xen
(from my application directory)
(compile)
rumprun-xen-cc -o simple.xen simple.c
(bake)
rumpbake xen_pv simple_baked.xen simple.xen
(using the MirageOS script, prepare for EC2)
sh ec2.sh -k simple_baked.xen
I then start it up on EC2:
The last part of the EC2 boot logilfe looks like:
