Just note this is a complex operation: 1. Remove from DC 2. Remove from all clusters 3. Remove from the configuration per all the hosts. Only then it becomes un-managed. Now for VM-Network which is assigned to VMs it may be even more complex - here we may need to block. If we don't then: If all VMs that are attached to the network are down - remove the network from all the VMs NICs and make them "None" If VMs are running, I have no idea how this could be solved. You can do as the above, but I don't see the engine sending re-wire command for each VM moving them to the null network. (In reply to comment #1) > Just note this is a complex operation: > 1.

When the network is removed from the DC, it is removed from the cluster, but remains on the host as an unmanaged network. Regarding a network that is assigned to a VM, I agree we should continue blocking network removal. (In reply to comment #2) > I'm not sure what you mean.

Yes, now that you say so, I remember that we do not have 'host configuration' saved in the DB, thus the only indication for managed/un-managed id it's existence in the cluster The problem is that it's a wrong approach and this is why it takes time for me to account for that. > Regarding a network that is assigned to a VM, I agree we should continue > blocking network removal. Behaviour of Update network will be modified as well to allow updating a network when network is assigned to a host. The network will simply become unsynced, and admin will be able to sync the network via Setup Networks.
