Hi,

i was using this guide 
https://alteeve.ca/w/2-Node_Red_Hat_KVM_Cluster_Tutorial_-_Archive to 
set up my cluster for some services, all works pretty good.

I decided to use this cluster as a HA vm provider for my network.

I have a little, maybe silly, question.

The guide tells me to disable qemu default network, like this:

>
>       Disable the 'qemu' Bridge
>
> By default, libvirtd <https://alteeve.ca/w/Libvirtd> creates a bridge 
> called virbr0 designed to connect virtual machines to the first eth0 
> interface. Our system will not need this, so we will remove it now.
>
> If libvirtd has started, skip to the next step. If you haven't started 
> libvirtd yet, you can manually disable the bridge by blanking out the 
> config file.
>
> cat  /dev/null>/etc/libvirt/qemu/networks/default.xml
i skipped the step to create the bridge device, as it was not needed for 
my belongings.

> vim  /etc/sysconfig/network-scripts/ifcfg-vbr2
> # Internet-Facing Network - Bridge
> DEVICE="vbr2"
> TYPE="Bridge"
> BOOTPROTO="static"
> IPADDR="10.255.0.1"
> NETMASK="255.255.0.0"
> GATEWAY="10.255.255.254"
> DNS1="8.8.8.8"
> DNS2="8.8.4.4"
> DEFROUTE="yes"


Now i want to know how to proceed?

i have bond0 - connected to my network (both nodes got different ip's 
from my dhcp)
bond1 & bond2 are used for corosync and drbd.

what would be the best decision to have some vm's served from this 
2-node cluster too?

thanks, and please tell me what infos i may have forgotten to provide 
for you. :)

cheers
