CloudStack supports 'cloud' workloads and 'enterprise' workloads as has been highlighted numerous times recently in e-mails comparing CloudStack to OpenStack.
Yes 'cloudy' workloads should not need this, but enterprise workloads most definitely do. This is something which regularly comes up on the user lists Regards Geoff Higginbottom D: +44 20 3603 0542 | S: +44 20 3603 0540 | M: +447968161581 geoff.higginbot...@shapeblue.com -----Original Message----- From: Chiradeep Vittal [mailto:chiradeep.vit...@citrix.com] Sent: 29 May 2014 05:27 To: dev@cloudstack.apache.org Subject: Re: [PROPOSAL] - Change Primary IP Address Curious: What is the reason to change the primary IP? Quite un-cloudy. @Wido: changing the IP in basic zone is quite involved, not just changing a dnsmasq entry.

This can also be found here : https://cwiki.apache.org/confluence/display/CLOUDSTACK/New+API+call+to+chang e+Primary+IP+address+after+VM+creation+in+Advanced+Zones I've started looking into this project although before anything is written I'd like community thoughts and feedback. Why only Advanced? I think this feature would benefit Basic Zone networks as well. I know that a lot of public cloud offerings use the Basic Zone networking and would love to see this feature. Wido ---- Subject: New API call to change Primary IP address after VM creation in Advanced Zones. Background: Currently the only way to change the IP address (via the API) is to drop a NIC attached to the VM and then add a new NIC with the desired new IP address. The process is as follows: 1. Add Temp NIC 2. Make Temp NIC default 3. Remove original NIC 4. Add NIC on same network as NIC removed in step 3, specifying IP as you add it 5. Make newly added NIC default 6. Remove Temp NIC This process works however it will mean the VM will see a new MAC address which could mean additional configuration is required. The existing API calls (removeIPFromNic & addIpToNic) only allow the user to modify the secondary IP addresses. This proposal is to create a new API call allowing the user to reset the IP address without the need to remove and add a new NIC. Requirements: 1. Add a new API call under the NIC section for root & admin users, allowing them to specify a new IP address for a given NIC e.g. amendIpToNic ( int nicId, string oldIpAddress, string newIpAddress ) 2. The system should check to ensure the new IP address that is being applied isn't already in use on the network. 3. The API call on success will require the virtual machine to be restarted for DHCP to be refreshed. 4. The functionality should apply to Advanced Zones. Comments: While we will perform a cursory check to see that the IP address isn't already in use, no other checks will be made. It will still be up to the domain administrator to manage IP allocation.
