Internet Access Problem

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

I am running Bullseye and attempting to use QEMU/KVM virt-manager, on 
the computers on my LAN rather than Oracle VM VirtualBox.

I particularly would like to be able to run Windows 10 as there in one 
application that I need for my molecular modeling research that is not 
available for Linux.

I followed the How To (HowTo.txt, attached) without any warning or error 
messages. However, when I pinged yahoo.com. I got the result:

Reply from 169.234.75.136: Destination host unreachable.

It is my understanding the internet should be reachable from Windows 10 
from the default connection.

The default virt-manger xml file and the host i pa results are also 
attached.

I would appreciate any sort of insight as to what might have gone wrong.

Thanks in advance.
