In "bridge mode", the guest interface acts like it has its own
cable to the local network - just without having to use a
seperate cable.

This means if the host needs to use DHCP to get an IP address,
so should the guest.

From what you posted as the content of etc/network/interface
it looks like you have the guest on a different subnet than
the host.

To see what the interfaces are available and how there are set
us ifconfig
Code:
# ifconfig -a
I'd try either changing the guest's the static IP address (how
it's currently set) to match the host's network - or change
the guest to use DHCP.
