BLUF: How do I configure the network for a warm site when the restored VM will have the IP address for the site that failed?
I'm going through all the SDN configuration options trying to figure out how I would be able to configure a Warm site without doing some sort of post processing for each VM to configure it for the subnet used at the warm site.
I've got two sites that I am using for my scenario site 1 is allocated the subnet 10.1.x.x/16; site 2 is allocated the subnet 10.2.x.x/16. Each site has more than 20 vlans with class c subnets for different purposes both in proxmox and on the physical network.
I have a proxmox cluster at each site and a proxmox backup server at each site. I am backing up each site to its local backup server and syncing the backups to the remote site. That makes the restore easy(haven't tested this yet) and allows for both sites to be a warm site for the other location. However the restored VM will be on the wrong subnet as I only have the gateway IPs setup for the subnets defined for the local site.
It seems like this would be a perfect use case for vxlan, however in a disaster the proxmox node at site 1 has failed with everything else at the site. I assume this would cause the vxlan to stop working properly and nothing would be able to reach the devices restored to the warm site that has the IP address of the failed site configured.
Am I right if so how would you do it? With the goal of not having to completely redo the network config during a disaster or redo the IP address for every VM you have recovered.
Thank you all in advanced for the assistance.
