Libvirt native C API and daemons
009464902a
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.
Further information about the libvirt project can be found on the
website:
