Linux – KVM VMs and virtual network, how to assign external IP addresses

bridgekvm-virtualizationlinuxnetworkingredhat

So, my question is: there is a remote server on Red-Hat with an external IP-address, eth0: inet addr: 87.112.140.53 Bcast: 87.112.140.255 Mask: 255.255.252.0, and is a virtual interface, which raises the kvm – virbr0: inet addr: 192.168.122.1 Bcast: 192.168.122.255

And I made two virtual machines that with that virbr0 received addresses at the interface via DHCP.

Problem: how to assign my VMs two external IP address from the network 87.112.140.0?

192.168.122.x are the default NAT networks set up by libvirt. If you want the VMs to be in the same network as the host, you need to set up a bridged network instead. take a look here: http://www.linux-kvm.com/content/using-bridged-networking-virt-manager
