I’ve set up a nested ESXi 6.7 + vCenter lab at home.
Initially, the vMotion portgroup was configured to use 2 active uplinks but I decided to experiment with just one uplink. However when looking at the data receive rate/data transmit rate network graph for the hosts, I still can see traffic going through the 2 vmnic when vMotioning VMs across hosts.
​[Receiving host. vMotion traffic received on vmnic0 and vmnic1](https://preview.redd.it/76367d8lc4j41.png?width=1545&format=png&auto=webp&s=2a8b643c29ab01a8522416c94ca9d39fa8629528)
​[Transmitting host. Note that vMotion traffic is sent by vmnic0 and received on vmnic1.](https://preview.redd.it/f5fl2mf7e4j41.png?width=1549&format=png&auto=webp&s=cf9c7657b73afe13a339e8beb8599b2540bd4d41)
I’m pretty sure my previous non-nested ESXi lab wasn’t showing this weirdness.
Is it a specificity of nested ESXi ?
(Promiscuous mode & Forged transmits are enabled on the physical ESXi host virtual switch).
