It may be an "HA resource type ip address".
Simple enough and been done for ages; what you're asking for is IP takeover. there's multiple ways to accomplish this and some are preferred over others depending on the OS of your VMs. Google is your friend.First of all I'd like to use a floating ip for virtual machines e.g. redundant HA proxy, ftp server
Just create 2 VMs and assign a floating IP to them. Of course you could use VM-HA, but you don't depend on distributed/remote storage (another point of failure).
Use cases:
- Floating IP for PVE management interface
- Assign floating IP to multiple VMs
- Manual trigger fail-over/back
- Specify timeouts
- Manual fail-over/back conditions (tcp port checks, HTTP response code, custom scripts, etc)
- Email notifications
I have no idea regarding feasibility or how it could be implemented.
