Guest ARP/network problem when using balance-alb

Hello,

I have a proxmox cluster with 4 nodes. 1 node is configured with balance-alb, so the vmbr0 is using the bond0 interface.

If I migrate my VM from 1 node to this new node with balance-alb, the network stops responding. The switch tells me that the VM MAC address changed to the one on the physical host.

How can I use balance-alb without losing guest network due to MAC/ARP problems?
