vmbr0 is the host’s bridge to eth0, so eth0 does not have any configuration. The host’s ip address needs to be setted on the vmbr0 interface. If you want your virtual machine to be bridged, you need to bridge it to vmbr0.
Supposing that 84.200.50.187 is the VM’s IP address, change the host’s network configuration as follow:
nano /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.0.24
netmask 255.255.255.0
bridge_ports eth0
bridge_stp off
bridge_fd 0
gateway 192.168.0.1
