When implementing sparse streams, one of improvements I did was to increase client buffer size for sending/receiving stream data (commit v1.3.5-rc1~502). Previously, we were using 64KiB buffer while packets on RPC are 256KiB (usable data is slightly less because of the header). This meant that it took multiple calls of virStreamRecv()/virStreamSend() to serve a single packet of data. In my fix, I've included the virnetprotocol.h file which provides VIR_NET_MESSAGE_LEGACY_PAYLOAD_MAX macro which is the exact size of data in a single packet. However, including the file from libvirt-stream.c which implements public APIs is not right. If RPC module is not built then the file doesn't exists. Redefine the macro and drop the include. The size can never change anyways. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
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.
