Note: MultiPortal is functional with Proxmox VE 9; however, during testing we identified issues with High Availability (HA). The deprecation of HA Groups in favour of Affinity Rules prevents proper group creation and breaks part of the API integration.
While general functionality remains intact, we recommend not upgrading to Proxmox VE 9 until MultiPortal is updated to support both Proxmox VE 8 Groups and Proxmox VE 9 Affinity Rules moving forward.
Proxmox VE 9 is not supported in production until testing and integration issues are resolved.
Please continue to deploy and maintain Proxmox VE 8 for all customer and internal environments.
Updates will be provided once official support for Proxmox VE 9 is available.
