I have been using qemu and qemu-devel with if_tap and if_bridge. The home network is a 192.168.1.0/24, I give the bridge a 192.168.1.x/32 address add tap0 and vr0 (the host machine's interface) as members, and give the qemu guest a 192.168.1.x/24 address with the same gateway as the host. This has worked perfectly through March. The host runs CURRENT. I didn't upgrade it through most of March, then finally had time to do a buildworld the first week of April. The bridged networking stopped working. The guest can only ping its own interface. Running tcpdump briefly indicated that nothing was reaching bridge0 or tap0 from the guest. Trying to figure out if it's a CURRENT issue or qemu issue, I threw a March snapshot of CURRENT on a second box, then qemu. I set it up as I usually do with bridging and it worked. I then ran buildworld and had the same result--the guest could no longer reach the outside world. I'm not sure what other information would help. I lack the time and expertise to try various dates of CURRENT and see exactly when this happened. Thank you for any pointers.

Do you have any idea how lonely it is, how dangerous? I would love to be upstairs watching TV or gossiping about boys or... God, even studying! But I have to save the world. Again.
