Set regions in the guest system that need to be added, modified or deleted
#include <qvm/gasp.h>
void gasp_region_set(struct guest_system *gsp, unsigned num_regions, const struct gasp_region *rgn)
This function is like gasp_region_set_soft(), with the difference that a fatal error will cause the function to terminate the running process (i.e., the qvm process instance with the vdev that called the function). To not terminate the running process on a fatal error, use gasp_region_set_soft().
