Thread-topic: [Xen-users] Network dies when downloading on dom0
>I'm running the following setup:

With the exception of Dom0/U OS, I run the exact setup :)

I had these same issues, do you run iptables in Dom0? I recall an issue
when doing so but I never tested the fix I just disabled it as Dom0 was
physically isolated.
