Hi Granwille, I am not aware of any other other way than adding another IP range.

This is an add-on question/problem if I do proceed with making these changes. In short, by creating a shared network for each IP range, once that range is fully used, you can no longer assign secondary IPs to VMs on the same NIC. So that would mean I need to add a new range to an existing shared network, just so that I can accomplish adding secondary IPs to a VM. Kinda defeating the purpose. Or is there a way around this.

Just one more question, I noticed a flaw or probably a lack of my understanding. When I have completed this process, and lets assume I have now maxed out all IPs on one shared network, how do I assign a secondary IP to a VM, but on the same NIC? With the current setup I have, because I have more than one range in my existing network, I have the option to assign secondary IPs to an existing NIC for a VM. It seems by following the advice I was given this does not seem to be possible any more when my range is maxed on one shared network. Is there a way around this? I created two new networks with each their own range now. But on my existing VMs, I do not see the option to add an IP address as a secondary IP to the existing NIC, because its on a different network. And for me to use the new network I have to assign an additional NIC, which is not really what I would want on a VPS. On 6/22/23 10:12, Jithin Raju wrote: Granwille, Your understanding is correct. If you want to assign the same IPs back to the original VMs you need to add the new network as additional NIC to the same VMs then change the new network to default and remove the old one. -Jithin From: Granwille Strauss <granwi...@namhost.com><mailto:granwi...@namhost.com> Date: Thursday, 22 June 2023 at 12:28 PM To: users@cloudstack.apache.org<mailto:users@cloudstack.apache.org> <users@cloudstack.apache.org><mailto:users@cloudstack.apache.org> Cc: Jithin Raju <jithin.r...@shapeblue.com><mailto:jithin.r...@shapeblue.com> Subject: Re: Moving Multiple Shared IP ranges from one Guest network Hi Jithin Thank you for getting back to me. Sorry, that came out wrong I make use of Advanced and not basic zone. That said, I am not sure I understand the following: Identify the IP range VR uses that needs to be retained in the network Change IP to the one range that you want to retain. Since my network has three subnets that are being used by VMs and one VR, do I understand correctly that I need to leave one range in place, the range that is tied to the VRs public IP, yes? And then, for the other two ranges, after I have stopped VMs and changed their IPs I can remove those two ranges and create two new networks for each range. Will I then be able to assign the old IPs back to the VM afterwards?

You want to create new guest networks right, but that is not possible in a basic zone. You could add a new pod and add the new subnets there but within the same guest network. If you are using an advanced zone with shared network you can follow the below steps: Stop VM Identify the IP range VR uses that needs to be retained in the network Change IP to the one range that you want to retain. Goto VM->NICs -> change IP Once you change the IPs for all the VMs you should be able to delete the range from the existing network and create a new one. -Jithin From: Granwille Strauss <granwi...@namhost.com.INVALID><mailto:granwi...@namhost.com.INVALID> Date: Wednesday, 21 June 2023 at 9:47 PM To: users@cloudstack.apache.org<mailto:users@cloudstack.apache.org> <users@cloudstack.apache.org><mailto:users@cloudstack.apache.org> Subject: Moving Multiple Shared IP ranges from one Guest network Hi Guys I have basic private cloud setup. I have one guest network that contains three shared public IP subnet ranges consisting of /28 and /29 ranges. I have been recently advised that it would be better to make a guest network for each subnet range instead of having them all under one network. The issue is, I already have VMs assigned to those public IP ranges and they're currently running. What would be the best way to solve this? Can I just remove the ranges from the existing network and quickly add a new network with those ranges and have a new VR boot up? Would it then continue to run on the existing VMs? I reckon I need to have the VMs stopped first in any case, yes? Also, I have ZERO API experience so this needs to happen all via UI. -- Regards / Groete [Image removed by sender.]<https://www.namhost.com/><https://www.namhost.com/> Granwille Strauss // Senior Systems Admin e: granwi...@namhost.com<mailto:granwi...@namhost.com><mailto:granwi...@namhost.com><mailto:granwi...@namhost.com> m: +264 81 323 1260<tel:+264813231260><tel:+264813231260> w: www.namhost.com<http://www.namhost.com><https://www.namhost.com/><https://www.namhost.com/> [Image removed by sender.]<https://www.facebook.com/namhost><https://www.facebook.com/namhost>[Image removed by sender.]<https://twitter.com/namhost><https://twitter.com/namhost>[Image removed by sender.]<https://www.instagram.com/namhostinternetservices/><https://www.instagram.com/namhostinternetservices/>[Image removed by sender.]<https://www.linkedin.com/company/namhos><https://www.linkedin.com/company/namhos>[Image removed by sender.]<https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA><https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> [Image removed by sender.]<https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner><https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> Namhost Internet Services (Pty) Ltd, 24 Black Eagle Rd, Hermanus, 7210, RSA The content of this message is confidential.
