I have a kvm/qemu/libvirt host with several VMs running happily on br0 with IP addresses that are in the same network as the host they run inside, 192.168.10.0/24.
So I'm playing with CoreOS and following their cluster guide Running CoreOS on libvirt as closely as possible. When I attempt to user their
deploy_coreos_libvirt.sh script, it can't find the virtual network "default." Indeed there is no virtual network defined according to
My Ubuntu 14.04.4 host has no example network/default.xml file but my CentOS 7 kvm host does. Again, both machines have no virtual networks defined. Below is the example network/default.xml from CentOS 7.
<network> <name>default</name> <bridge name="virbr0"/> <forward/> <ip address="192.168.122.1" netmask="255.255.255.0"> <dhcp> <range start="192.168.122.2" end="192.168.122.254"/> </dhcp> </ip> </network>
So if my physical lab network is 192.168.10.0/24, what network should I use for my virtual network? The user_data example on the CoreOS page has "Network": "10.1.0.0/16". Should I use that in the virtual network config?
