The test programs in the tests/ directory use a block device to communicate
the "test result" back to the host. Not ideal, but the most straightforward
way to do things now.
If you just want to experiment with simple programs, any standard C program
will do, e.g.
----
#include <stdio.h>
#include <unistd.h>
int main()
{
printf("Hello, World!\n");
return 0;
}
----
Build with: rumprun-xen-cc -o hello hello.c
Run with: rumprun xen -i ./hello

I'm not sure what this and the following panic is about. Antti?
