Lets start with the main symptoms; 1) Slirp guestfwd is broken, start an nc with: nc -l 127.0.0.1 4444 and then qemu with: -netdev user,id=3Dunet,guestfwd=3Dtcp:10.0.2.50:4444-tcp:localhost:44= 44 -device e1000,netdev=3Dunet=20 and from the guest do: seq 1 10000000 | nc 10.0.2.50 4444 & you should get a spew of numbers coming out of nc but on current head it does nothing. This seems to work at becdfa00cfa2995e859ccefa4b7d72a72eb96581 but segs by 386f07d1fc02fb4316039994b855c4feb9b091ce and is silently broken somewhere around 72ac876248ca2d33b3e1170b2f86f= b68daaacdc8 2) If you start qemu with qemu-system-x86_64 -nographic you normally get no output until you ctrl-a c at which you get a banner and then a (qemu) prompt, however with current head, at startup you get: ./x86_64-softmmu/qemu-system-x86_64 -nographic QEMU 2.7.50 monitor - type 'help' for more information (qemu)=20 and although it gives you a prompt it's not responsive, so you ctrl-ac and then you get a : QEMU 2.7.50 monitor - type 'help' for more information QEMU 2.7.50 monitor - type 'help' for more information (qemu)=20 =20 and it works - but you've got the extra banner. It's fine at 6dfa8298faa0fce47c68659fd4d92e76745d4edb ecb672d14f092f481000ac9cd9d7dc0500692eba is broken but a bit different= ly 94a40fc56036b5058b0b194d9e372a22e65ce7be doesn't build (!)
