I am sure I am missing something fundamental here. I have been working with ESX 5.5 to setup a new deployment with virtual distributed switches using LACP (this is new to me). I seem to have run into an issue where following a vmotion the VM is no longer accessible from the network until I migrate the vm network to a portgroup on the local host. i.e. One portgroup per host which contains 4x 1gb ports configured for LACP.
So lets call this host A and host B and the VM linux. Both hosts have a 4 port LACP port group which resides in the same virtual distributed switch. linux has a network adapter in the h1-portgroup which contains the interfaces on host A. The h2-portgroup contains the interfaces on host B. When I vmotion a VM from host A to host B I lose network access to the VM until I go in and do a network migration for said VM from the host A port group to the host B port group. Essentially all this is doing is moving the network adapter to the h2-portgroup. I am not sure if my understanding of this is just flawed but when I do a vmmotion I expect, or would like, for the VM to re-associate its network adapter to the h2-portgroup.
Any help would be greatly appreciated.
Do you see anything in vcenter logs?
I'm confused- why do you have portgroups per host? Generally you would want the same port group on your dvSwitch, and each host will have NICs in the uplinks portgroup.
Could you post a screenshot of the switch config?
