Domain migration source code interpretation in xl/libxl (xen-4.1.2)
Hi all, I am trying to understand domU migration in xen-4.1.2/tools/libxl/xm_cmdimpl.c. Here are my questions: 1) Is there any documentation which explain each functions? 2) What is the difference between these two functions: int main_migrate(int argc, char **argv) and int main_migrate_receive(int argc, char **argv)? 3) In the function: static void migrate_domain(const char *domain_spec, const char *rune, const char *override_config_file) , what does: *) save_domain_core_begin(domain_spec, override_config_file, &config_data, &config_len); *)migrate_read_fixedmessage(recv_fd, migrate_receiver_banner, sizeof(migrate_receiver_banner)-1, "banner", rune); *)save_domain_core_writeconfig(send_fd, "migration stream", config_data, config_len); *)migration_child_report(child, recv_fd); *)Finally, which section of the" migrate_domain" function performs memory copy from the initial host to the target host? Please, apologize the number of questions. Thanks in advance for your answers.
