CentOS 7 host with guests as bridge cannot access host
This is unfortunate.

To the "normal" user - BRIDGE means guest is on the same network and has
access to the host.
Bummer.

net interface direct - no IP communication between guest & host
hi everyone
I wonder why, when I attach an interface like this:
virsh # attach-interface --domain win10Ent --type direct
--source nm-team --config --persistent --model virtio
host cannot ip ping the guest and vice versa, yet guest can
ping other nodes(outside of its host, connected via phys net
via a switch)
Would you know?
I thought maybe routing on the host, so I did:
$ route add -host

I expect you'll be hitting this unfortunate gotcha:

Thanks I was using iptables and not converted to firewalld. I am doing so
now.
Will I need to delete the VM and re-add it ?
I am rebooting first.
