dedicated migration network in ring_1?

[HFernandez]

Hi, I have a corosync with high availability, the question is if I can use the ring_1, the ip and network board to set it in the migration network?

ring_0 = 192.168.11.2
ring_1 = 192.168.12.2

/etc/pve/datacenter.cfg file:

# use dedicated migration network
migration: insecure, network = 192.168.12.0 / 24

Hi,
please do not use any of the corosync network rings for migration. It is strongly recommended to use a dedicated network for this.

Ok, I understand, this means that the migration network uses the bond that vm uses, right?

I have the IMM boards of the servers that I only use to see their status, can I use those boards?

By default migration does use the cluster network, but you should use a high bandwidth network for the migration traffic instead.
See the docs and especially the example there https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_guest_migration
