The doc is incorrect. I'll make sure its fixed for the next release.

Wow, that is precisely correct Alena. Thank you! I will test later today and confirm if that
fixes it.

I was misled by the the Admin Guide: "Conserve mode. Indicate whether to use conserve mode.
In this mode, network resources are allocated only when the first virtual machine starts in
the network."

>From that description, I assumed conserve mode meant that it would not boot the router
and allocate an IP until the first VM is provisioned rather than that it would not allow an
IP to hold multiple roles. We definitely want to use conserve mode, so I will change our network

I'm trying to switch from one network offering to another, and receiving an error when switching:

"There are multiple services used ip <public IP of Virtual Router>".

This occurs when switching any network  it's not isolated to one. The differences between
the current network offering and the new network offering are that there is a higher network
rate, and also that redundant virtual routers are enabled.

This is running CloudStack 3.0.1.

Any clues?


Looks like these 2 offerings have different values for conserveMode. The original offering
has conserveMode = true, which means that single public IP can be used for multiple services
at the same time (PF/LB/StaticNat).
The offering you are trying to upgrade to has conserveMode=false - the Ips can't be used for
more than one service at a time. The fact your original network has public Ips used by multiple
services makes upgrade to the offering with conserveMode=false impossible.

Please confirm that this is your case.
