> We provide redundant routers with HA functionality through a special service offering.
> However these router pairs are provisioned with ha_enabled=0, so when one or both of
them fail they will never be restarted by CS. 
> 2013-08-16 15:51:16,101 DEBUG [cloud.ha.HighAvailabilityManagerImpl] (HA-Worker-0:work-4335)
VM is not HA enabled so we're done.
> This is currently hardcoded in VirtualNetworkApplianceManagerImpl.java @ 1633
>    boolean offerHA = routerOffering.getOfferHA();
>                 /* We don't provide HA to redundant router VMs, admin should own it all,
and redundant router themselves are HA */
>                 if (isRedundant) {
>                     offerHA = false;
>                 }
> We like redundancy and like to have HA on our redundant routers. We like to configure
this ourselves through service offerings and do not like being helt hostage by these lines
of codes:) We do like to own it all in our admin role :)
> Besides this, this is also very counter-intuitive as we were expecting HA on our redundant
routers, since it was configured on their service offering.
> So can we get rid of these lines of code? And have this controlled through service offerings
as it should IMHO.? Unless this has negative impact which we are not aware off?
> Cheers & Thanks,

> bug 12608: NaaS: Don't shutdown elements if cleanup=false
> We can use the restartNetwork mechanism to recover the disconnected redundant
> router.
> Also disable HA for redundant router. Admin would take responsibilty to recover
> the failure router, because redundant routers themselves are one layer HA.
> status 12608: resolved fixed
