When using bridge-networking it looks as if your interface has two MAC- addresses, one used in the host and one used in the guest. Your Ethernet interface is enabled to take all packages (promiscuous mode) and the filtering for the right MAC address is done in the host. The MAC address used for the guest is more or less randomly chosen when initializing the guest. You can change the address when (re)configuring the guest in the host. The name of the interface is chosen based on the hardware position of the interface. In the guest it is based on the virtual hardware position, so it is quite possible to have another name than the interface in the host. The IP address of your host is apparently a fixed address, so you do not use a DHCP server in your network. In case you do not have a DHCP server in your network, apparently you do not have one, you have to configure the same type of parameters in your guest as in your host. Logically you have two separate systems in your hardware, which need both the same type of configuration. So you need to configure, without a DHCP server, the IP address, the netmask, the default gateway and the DNS address(es) in both the guest as in the host. Obviously the IP addresses of the host and the guest must be different, but part of the same subnetwork. -- fr.gr.
