I'm not a VMWare expert but I suspect that you forgot enabling the
Promiscuous Mode on the vSwitch where your virtual host is connected.
vSwitch doesn't implement a MAC Learning algorithm and so only the frame
addressed to a well known MAC address (such as the interfaces of host which
is running as a VMWare virtual machine) will be sent over the right virtual
port, other frames (the ones addressed to the hosted-engine nested VM for
instance) will be lost.
Promiscuous Mode mode will fix this behavior but of course it will also
impact on the performance.
