RE: [Add/Remove Network to VM] Multiple NICs on same Guest Network

2013-04-15 Thread Saksham Srivastava 
We have a feature Multiple IPs on the same NIC 
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Multiple+IP+address+per+NIC

Isn't the functionality covered by this feature.

I do not see a strong use case for having both the features (Multi NIC in same 
network and Multi IP per NIC).
Should we allow only one of them, as they both tend to serve the same purpose, 
or am I missing something?

Thanks,
Saksham

I believe it was allowed because one can also create multiple NICs on the same 
network while deploying a VM.

There may be people doing that to get multiple IPS auto-assigned to a VM.

Hi,

Using addNicToVirtualMachine API user can add multiple NICs to a VM

I am also able to add multiple NICs to a VM on the same isolated guest network.

Is this a valid scenario??
If yes what could be the use case for the same?

The reason to choose multiple ips is  there is a limit (I think it is 7) on the 
hypervisor about number of nic can VM have.
For a nic you can have more than 7 ip addresses.
The multiple ips feature is supported in the basic zone also.

I think multiple nics feature is more useful when user need a nic in different 
network.

 The functionality was duplicated from deploy allowing multiple NICs, and I
 wasn't involved in the discusion as to why that was decided. There could be
 other reasons why that was put in place, I don't know. At any rate it doesn't
 hurt anything in particular, and I'm not sure how many are using the
 capability in 4.0 and earlier, but they may have gotten used to it.
