To save you the hassle of pushing the vib to each ESXi host, you can also install it by pulling it directly from the VRMA via HTTPS.

SSH to the ESXi Host and temporarily disable it's firewall:

      esxcli network firewall set --enabled=false

Install the vib: (NOTE: vmware-hbr-agent.vib is an alias for /opt/vmware/hbr/vib/vmware-hbr-agent-{version-build}.vib - which in my case is vmware-hbr-agent-6.8.6-1.1.14221959.i386.vib)

     esxcli software vib install -v https://{VRMA IP or FQDN}:8043/vib/vmware-hbr-agent.vib

The installation can take a minute. Nothing is displayed on screen until it is complete.

Don't forget to re-enable the firewall:

      esxcli network firewall set --enabled=true

Done.

If you are replicating to the cloud you can also install the vr2c-firewall.vib in the same way. It's URL is https://{VRMA IP or FQDN}:8043/vib/vr2c-firewall.vib

Hope this helps someone.
