Re: [Rdo-list] VM instance will not start



Could I use the nova commands to remove the network, then add it again? i.e. nova network-delete <ID>; nova network-add <options>

Yes, that's right. An additional caveat: any networks that have already
been created have a field in the database that indicates that it is for
multi-host and IIRC won't work any more. You can try logging into the
database and tweaking the appropriate field to N (or whatever
constitutes false in that case). Alternatively, you have to redeploy.
Yeah.. changing network configs in nova-network can be a pain.

Cheers,

Brent
