I must be doing something wrong:

Have set up a basic Xen system, Dom0 + one Xen0 guest. Configured for
a routed network.

Ping Dom0 -> guest works.
Ping guest -> Dom0 works.

nmap Dom0 -> guest reports port 22 open.

Ssh Dom0 -> guest hangs.
ssh guest -> Dom0 hangs. Same behaviour. Watching a packet capture
shows traffic passing but with retransmits and poor performance.

If I build a gre tunnel between Dom0 and guest, everything works fine,
with the exception that I must generate some traffic from the guest
first.

I have no iptables rules configured, so it's not that. Looks like
there is maybe some issue with tcp traffic between domains.

Looks like a bug to me, but I'm posting to the user list first.

I am running unstable from last friday.
