I have CentOS 7 host. Two guests on bridge network setup by GUI and virt-manager. 1 CentOS 8 guest 1 Win 10 guest Both cannot access the host. They can other machines on the network. Guests can access the internet just not the host.
I used virt-manager GUi to set up everything. Selected the eth0:macvtap and Bridge. I "desire" bridge network.
If I select something else I get access to host - but of course machine is not on the main network.
Thoughts ?
