Hi, Kurt. I assume the Citrix XenServer API you are mentioning is XAPI. This
is probably still your best route for configuring VLANs and networks, since
Open vSwitch is tightly integrated with recent versions of XenServer. I'd be
worried about changing things from underneath it--especially since local
network configuration isn't persistent across reboots.
To configure things not natively understood by XenServer (e.g., NetFlow,
mirrors, OVS's concept of QoS), you have a few options:
- You can use ovs-vsctl directly on the host or remotely by configuring
ovsdb-server to listen on a TCP or SSL socket.
- You can implement a configuration database manager, which
ovsdb-server will sync up with through its JSON-RPC protocol (documented in
ovsdb/SPECS).
- You can talk to Citrix about whether there is an API provided through
the DVS (distributed virtual switch), which is available in some 5.6.0 FP1
configurations.
If you want to configure flows/policies in the switch your best bet is through
OpenFlow or DVS.
