If you have different subnets you need a router, not a bridge, and
a "default route on other subnet" is an oxymoron.

dom0 is 10.1.1.1/24 on the real interface and 10.1.1.254 is the gateway.

domU is 10.2.2.2/24 and needs a gateway in 10.2.2.0/24, e.g. 10.2.2.254.

dom0 needs a second interface to be configured for 10.2.2.254. This can
be a bridge that is used by multiple domUs, all in 10.2.2.0/24.

dom0 needs to be configured for ip forwarding.

your gateway 10.1.1.254 needs a proper route to 10.2.2.0/24 pointing
to the dom0. Other machines in 10.1.1.0/24 either need the same or
routing redirects have to work (they usually do).
