Agreed. Much better.
Thanks a lot for the review Laine. I'll send the updated v3 today.

Changes to the parser/formatter should be in the same patch as the
schema/docs changes.
Agreed! Thanks

specifically disconnect from standard bridges (unlikely but possible),
I think these if's shouldn't be nested. Instead it should be:
if (vpor && vport->virtPortType == OPENVSWITCH) {
ovs stuff
} else if (vport && vport->virtPortType == MIDONET) {
midonet stuff
}
(that way we can just add an "else" clause if we have to without
restructuring anything else).

See the comment above. Same applies here.

I know you didn't create the problem in this case, but I think here the

logic should be the following:
if (virtPortProfile && virtPortType == OPENVSWITCH) {
virNetDevOpenvswitchAddPort(blah)
} else if (virtPortProfile && virtPortType == MIDONET) {
virNetDevMidonetBindPort(blah)
} else {
virNetDevBridgeAddPort(blah)
}
That way if someone specifies a <virtualport> as a placeholder, but no
type, they will still get attached to a standard bridge (which is almost
surely what they will expect).
Agreed. Much better.
