> simon, can you please add the required wording for the message.

First why this is blocked in the first place? 
Removing a network that is not in use should be allowed even if the host is not in maintenance mode. I think that we've discussed this in the past. If you don't it's a regression compared to 3.0.

Now if the network is in use, and the only use we can detect is if there are VMs using it or it is a display/rhevm network:
   "Network can't be removed while it is in use by the host"
Comment 3 Martin Pavlik 2012-08-30 11:09:22 UTC 
I tried to reproduce the scenario on IC157 It is blocked as well. 

Error message:
dell-08:
•	Network is in use by a cluster
Comment 4 Muli Salem 2012-08-30 11:27:03 UTC 
So, is the following message that Martin suggested OK?:

Cannot edit Network while Host is Active, change the Host to Maintenance mode and try again.
Comment 6 Martin Pavlik 2012-08-31 06:05:30 UTC 
Adding correct Simon
Comment 7 lpeer 2012-09-02 08:05:12 UTC 
According to comment 3 this was the behaviour in 3.0.
Muli, the text you suggested in comment 4 is good, please use it
