No connectivity between Host and VM machine

Hi,

I have an host running Red Hat and KVM.

From my laptop, I can reach the host through management VLAN.
I had to configure eth0.10 subinterface to have connectivity.

Code:eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

From the host, I cannot reach the VM.
Please check guest.jpg to see what I have configured.

Besides, from the Virt Manager I can see that for NIC *3b I have:

Network source - Host device eth0: macvtap
Source mode - bridge

What am I missing?

Thanks.
