virSocketAddrIPv4 is a type used only internally by virsocketaddr.c. It is defined to be a character array, which leads to multiple occurences of extra bit fiddling and byte swapping for no good reason (except to confuse). An IPv4 address is really just a uint32_t with the bytes in network order, which is exactly the type of the s_addr member of the sockaddr_in that is a part of the publicly consumed struct virSocketAddr, and that we are copying in and out of a virSocketAddrIPv4. Sometimes it's simpler to just treat it as a network-order uint32_t, so let's make our virSocketAddrIPv4 a union that has both an unsigned char bytes[4] (for the times when we need to look one byte at a time) and a uint32_t val (for the times when it's simpler to treat it as a single value). For now we just change all the uses from, e.g. x[i] to x.bytes[y]; an upcoming patch will simplify some of the code to remove loops by using x.val instead of x.bytes when appropriate.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
