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 ?
