Which interface is used for VM state and storage migration?

[pxmxadm]

I have a cluster with local and NFS storage for VMs. From what I understand, there are two types of VM migrations:
* VM state (from pve01 to pve02)
* VM storage (e.g. from one NFS storage to another, in between NFS and local storage, etc)

In Web UI, it has datacenter > options > migration settings where I can choose the interface for "migration." which type of migration does it refer to? I am trying to make sure such traffic are not competing with the VM guest traffic.

thank you.

Hi,
only migrations across nodes will use that network. Disk move operations involving NFS storages will use the configured server IP/hostname to read/write to the storage. In case a hostname is used, the actual network depends on the host's network configuration.
