The API can be used to create a VM with multiple nics in the same
network. The logic to prevent this in the UI only. You just have to
specify the same NetworkId as a comma-seperated list. so the following
works atm:
deployVirtualMachine
&templateId=ttt
&serviceOfferingId=sss
&networkId=nn,nn
Most likely the default gateway gets clobbered and only one NIC is in
use at all times. The other being passive.
Just Curious, What would be a use-case for such a requirement though?
Thanks,

Thanks .
I had a server with 10 ipaddress i modify the router script to make the
nat to that IPs.
I would be a great feature to have the possibility to add "floating
Ip's" in the private network and nat 1:1 to a public IP.

No, it's not possible. Although seems like you can assign 2 nics from the
same network to the vm, the things start breaking when we create network
rules (firewall/pf/lb) for vm in the network. As we always assume that vm
can't have more than one nic in the network.

It's possible to NAT 1:1 a public IP for each of this Privates IP's? To
do that at this moment i modify the script in the VP.
Thanks
