Your appliance has it set to ovirt1.test.lab.
Are these pointing to the same IP address?

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.

[ovirt-users] Networking issues on Hosted Engine Appliance

[Bryan Sockel]

Having some issues with my Hosted Engine Appliance,  I am able to get it up 
and running, and i can access it only from the server that is hosting it.  
The host server can ping the appliance, and the appliance can ping the host 
server.  The host server can ping the rest of my network and get out to the 
internet.

This is a nested setup i am using for testing and poc and is running on a 
vmware platform.
