I have proxmox host (8.4.5) with 2 physical interfaces connected to TOR switches and used bond0 in active-passive mode. when one of the interfaces goes down, failover happens immediately to other interface and host side is good. But the VMs running on the host lost the network access for 30sec to 5min and then start respond to ping. When i put the continuous ping inside the VM and perform the same test, everything is working as normal ( both VMs & host). Did anyone have this similar behavior ?
