So what do you use now? routing? bridge to virbr0?

does the problem occur on your "ethernet ports locked to a single Mac
address" environment, or "at home and connected to my Home-Hub"
environment?

who sets that? by default any OS installation does not have http_proxy
environment variable. User must set it manually.

the same question, who sets that?

how did you determine it's not cleared? what's the output of
echo $http_proxy
echo $HTTP_PROXY

There's no such thing.
the only thing dom0 can pass to domU is in the form of kernel extra
line. And that's only when you put kernel on dom0.

Again, what is the current content of those variables?
Does your ISP uses transparent proxy?

Short answer, it should have nothing to do with Xen.
It has everything to do with the configuration of whatever OS your
domU is running, and how your ISP sets up networking (like transparent
proxy).
