I have a network card, and it is setup with:
ip addr add dev enp5s0 10.0.0.61/24
ip link set dev enp5s0 up
ip route add default via 10.0.0.1
brctl addbr br0
brctl addif br0 enp5s0
ip link set up dev br0
then I use the br0 bridge with a virtual machine and I am able to connect to the internet and all is working fine from the guest host.
But the moment do "ip link set up dev br0", I am not able to use the network from the host machine.
I thought about having a tap device that was added to the bridge. I tried some stuff that I was not able to get to work, so I am a bit lost at this point.
How can I configure it so the network is usable from the host and the virtual machine guest at the same time?
Thanks.

I don't see any use in setting up a bridge with just one interface. Shouldn't a bridge connect to interfaces with each other?
Which VM software are you using?
I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do. (Gune | Titan A.E.)

qemu creates a tap device and attaches it to the bridge with:
qemu-system-i386 -net nic -net bridge,br=br0
And that works great, network inside virtual machine is ok and all.
To get network access for the host I tried to create another tap device and add it to the bridge:
ip tuntap add mode tap enta
ip addr add dev enta 10.0.0.62/24
brctl addif br0 enta
ip link set dev enta up
The enta device shows: no-carrier ... master br0 state down...
So probably something is missing here, probably me not doing the right things here...
