[libvirt] [PATCH v4] vepa: parsing for 802.1Qb{g|h} XML

Below is David Alan's original patch with lots of changes. In particular, it now parses the following two XML descriptions, one for 802.1Qbg and 802.1Qbh and stored the data internally. The actual triggering of the switch setup protocol has not been implemented here but the relevant code to do that should go into the functions associatePortProfileId() and disassociatePortProfileId(). <interface type='direct'> <source dev='static' mode='vepa'/> <model type='virtio'/> <vsi type='802.1Qbg'> <parameters managerid='12' typeid='0x123456' typeidversion='1' instanceid='fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f'/> </vsi> <filterref filter='clean-traffic'/> </interface> <interface type='direct'> <source dev='static' mode='vepa'/> <model type='virtio'/> <vsi type='802.1Qbh'> <parameters profileid='my_profile'/> </vsi> </interface> I'd suggest to use this patch as a base for triggering the setup protocol with the 802.1Qb{g|h} switch. Changes from V3 to V4: - moving the associate and disassociate functions to the end of the file for subsequent patches to easier make them generally available for export - passing the macvtap interface name rather than the link device since this otherwise gives funny side effects when using netlink messages where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev all of a sudden gets the MAC address of the macvtap interface. - Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case we wanted to use hook scripts for the setup and so the setup doesn't fail here. Changes from V2 to V3: - if instance ID UUID is not supplied it will automatically be generated - adapted schema to make instance ID UUID optional - added test case Some of the changes from V1 to V2: - parser and XML generator have been separated into their own functions so they can be re-used elsewhere (passthrough case for example) - Adapted XML parser and generator support the above shown type (802.1Qbg, 802.1Qbh). - Adapted schema to above XML - Adapted test XML to above XML - Passing through the VM's UUID which seems to be necessary for 802.1Qbh -- sorry no host UUID - adding virtual function ID to association function, in case it's necessary to use (for SR-IOV) Signed-off-by: Stefan Berger <stefanb(a)us.ibm.com&gt;
