Hi All In order to use a libvirt network with forward mode='route', you must have an *entire subnet* available to assign to the libvirt network, and the rest of your physical network must have a route entry for that subnet which points to your host's physical-side IP address as the gateway. Since you say that you only have 192.168.111.1 - 192.168.111.25 available, I am guessing that you don't have an entire subnet, and that you probably aren't able to alter the routing tables of routers on the physical network, so routed mode will not work for you. If, instead, the case is that your host's physical-side (i.e. em1) IP address is 192.168.111.2, you should instead investigate putting a Linux host bridge on that interface, and configuring the guests for a bridged network connection: http://wiki.libvirt.org/page/Networking#Host_configuration_2 We would like to do exactly as mentioned in this link https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/sub-sect-routed-mode-libvirt.html |
