This patchset adds the ability for libvirt users to control interface link state of the virtual network devices provided by hypervisors. Modification of the link state is accomplished by adding a new XML element <link state"up"> or "down" to the domain XML. The corresponding network interface is thereafter initialised with the desired state. Live modification of the link state is achieved by calling virDomainUpdateDeviceFlags containing a modified interface configuration. Yet, users may modify only link state of an interface. This feature allows propagation of network topology changes to guests, testing scenarios in complex virtual networks, etc ... Future upgrade: - add support for VirtualBox Modifications to v2: - Rebase to curent HEAD Modifications to v1: - use virUpdateDeviceFlags instead of dedicated API - incorporate helpful comments by Eric Blake https://bugzilla.redhat.com/show_bug.cgi?id=643373 Peter Krempa (5): link-state: util: Add equality comparision functions for structures link-state: conf: Add element to XML for controling link state link-state: qemu: Add monitor handling for link state modification link-state: qemu: Add net intf modification to virUpdateDeviceFlags link-state: virsh: Add wrapper commands for changing link state docs/formatdomain.html.in | 21 +++ docs/schemas/network.rng | 11 ++ src/conf/domain_conf.c | 24 ++++ src/conf/domain_conf.h | 11 ++ src/qemu/qemu_driver.c | 24 ++++ src/qemu/qemu_hotplug.c | 176 ++++++++++++++++++++++++++ src/qemu/qemu_hotplug.h | 8 ++ src/qemu/qemu_monitor.c | 19 +++ src/qemu/qemu_monitor.h | 4 + src/qemu/qemu_monitor_json.c | 23 ++++ src/qemu/qemu_monitor_json.h | 4 + src/qemu/qemu_monitor_text.c | 46 +++++++ src/qemu/qemu_monitor_text.h | 4 + src/qemu/qemu_process.c | 47 +++++++- src/util/network.c | 62 +++++++++ src/util/network.h | 5 + tools/virsh.c | 286 ++++++++++++++++++++++++++++++++++++++++++ tools/virsh.pod | 11 ++ 18 files changed, 785 insertions(+), 1 deletions(-) -- 1.7.3.4 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
