Proxmox VE Dedicated Migration Interface

In the video below, we show you how to configure a dedicated migration interface for Proxmox VE

We show you how to re-configure the management interface created during the installation so that it is in your management VLAN

By default this traffic will be sent over the interface Proxmox VE was configured with when it was installed

And that can cause remote management and user connectivity issues for instance

Because even if a VM’s hard drive is on shared storage, a live migration requires transferring the VM’s RAM

Provided the hypervisors have multiple physical or partitioned interfaces, you can assign a specific interface to carry this migration traffic and avoid oversubscribing other interfaces

NOTE: If you are using the firewall in Proxmox VE, you will need to allow SSH traffic between the hypervisors on this interface

Sharing is caring!
