Hi,
Sorry of this is the wrong list, trying to find some help.
I am trying to set up 2 KVM hosts using Debian 9 (connecting to a 3 node Centos 7.4 gluster cluster) To get the bandwidth I have bonded 2 NICS each end. However while the network works fine for the Debian VM host the VM guests cannot connect/get an IP using DHCP connecting to br0. (Same setup on the Centos end works fine however)
On the Debian host if I connect to br1 which is a bridge to a NIC port it works fine. My problem then seems to be at the bonding layer for libvirt/kvm ?
Here is my interfaces config, I cannot see the problem. The VM guest is on the gluster cluster and boots fine just no networking.
any ideas what I am doing wrong pls? or a better group/list to go ask in?
