I am using KVM over centos7. My question is regarding networking issue that I am having in my setup.
I am using
Bridge Br1: Host device vnet0 for all kvm instances.
I have instance 1 and 2-5. Where 1 communicate with all 2-5 instances, the communication is full duplex. Instances 2-5 don't communicate each other.
At certain point the network goes down and it takes sometime to come up again.
