Subject Re: Change Network Offering from HA to another without HA

Nice, glad you got it sorted.

If you have the opportunity it would be very beneficial if you can reproduce this issue in
a non-critical network and log a Jira ticket.

    The field “redundant” in table cloud.networks is not modified after the change of
the network offering, i modified manualy  the value of "redundant" to false and the problem
was resolved :)

Can you check the following:

    > The check two things:

without HA / redundant VR ( you can check this with SELECT * FROM cloud.network_offerings;).
    > 2) Check that the “redundant” field comes back as zero – “0”
    > My suspicion is you have the correct network offering in step 1, but you may find
the redundant field is set to one  “1” – which would potentially cause the problem you
are describing.
    > I managed to recreate the problem by changing the “redundant” field for an isolated
network from 0 to 1 – at which point another VR was created next time I created a VM. I
then managed to fix this again by changing the network back to a redundant=0 before restarting
the network with cleanup. This deleted both the running VRs and created a single healthy one.

La conectividad se mantiene y funciona todo de forma normal. Pero al crear una nueva VM en
el Domain se vuelve a crear un VR redundante provocando cortes en la conectividad.
