Subject Re: XenServer & Open vSwitch
Date Tue, 31 Jan 2017 15:07:24 GMT
Hi Eric,

My understanding as follows:

- XenServer with basic networking only works when using the “old” linux switching backend,
not OVS, due to the requirements to manage security groups.
- OVS plugin comes into play in advanced zones where you want to use SDN/L3 overlay networks
to provide guest isolation (which you don’t do in basic zones).
- Keep in mind this only applies when you want to use SDN, if you want to use standard VLAN
based advanced zones then XenServer will just use OVS as it’s standard switching backend
(since XS6.2).

Hope this helps.

    I'm confused by the documentation that I've found:
    This page states that "If the XenServer host is part of a zone that uses
    basic networking, disable Open vSwitch (OVS)":
    This page states that "The following hypervisors are supported by the OVS
    Plugin: XenServer >= 4.0":
    Will the OVS Plugin allow CS to manage XenServer when using the Open
    vSwitch network backend (in a Basic Networking scenario and/or an Advanced
    Networking scenario)?
