[libvirt] [PATCH 0/5] Introduce API to query IP addresses for given domain

This feature has been requested for a very long time. Since qemu guest agent gives us reliable results, now the wait is over. The RFC was first proposed by Michal Privoznik: http://www.mail-archive.com/libvir-list@redhat.com/msg51857.html A patch was submitted, using structs: http://www.mail-archive.com/libvir-list@redhat.com/msg57141.html Another patch was submitted, using XML: http://www.mail-archive.com/libvir-list@redhat.com/msg57829.html Neither of the patches were accepted, probably due to lack of extensibility and usability. Hence, we thought of using virTypedParameters for reporting list of interfaces along with their MAC address and IP addresses. The RFC can be found here: http://www.mail-archive.com/libvir-list@redhat.com/msg79793.html The idea of extensibility was rejected and rendered out of scope of libvirt. Hence, we were back to structs. This API is called virDomainInterfacesAddresses which returns a dynamically allocated array of virDomainInterface struct. The great disadvantage is once this gets released, it's written in stone and we cannot change or add an item into it. The API supports two methods: * Return information (list of all associated interfaces with MAC address and IP addresses) of all of the domain interfaces by default (if no interface name is provided) * Return information for the specified interface (if an interface name is provided) The API queries qemu guest agent to obtain ip addresses and MAC address of each interface the given domain is associated with. In the future, support for more flags will be added to support for DHCP and snooping methods nehaljwani (5): domifaddr: Implement the public API domifaddr: Implement the remote protocol domifaddr: Implement the API for qemu domifaddr: Add virsh support domifaddr: Expose python binding daemon/remote.c | 123 ++++++++++++++++++++++++++++++++ examples/python/Makefile.am | 2 +- examples/python/README | 1 + examples/python/domipaddrs.py | 50 ++++++++++++++ include/libvirt/libvirt.h.in | 32 +++++++++ python/generator.py | 1 + python/libvirt-override-api.xml | 8 ++- python/libvirt-override.c | 117 +++++++++++++++++++++++++++++++ src/driver.h | 7 ++ src/libvirt.c | 99 ++++++++++++++++++++++++++ src/libvirt_public.syms | 5 ++ src/qemu/qemu_agent.c | 150 ++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 4 ++ src/qemu/qemu_driver.c | 57 +++++++++++++++ src/remote/remote_driver.c | 93 +++++++++++++++++++++++++ src/remote/remote_protocol.x | 32 ++++++++- src/remote_protocol-structs | 24 +++++++ tools/virsh-domain-monitor.c | 103 +++++++++++++++++++++++++++ tools/virsh.pod | 10 +++ 19 files changed, 914 insertions(+), 4 deletions(-) create mode 100755 examples/python/domipaddrs.py -- 1.7.11.7
