+-net socket,connect/listen does not work in 2.7.0
+
+Using 2.7.0 release on Debian Sid. What I did: start one VM with:

+typing "ping -c 1 10.0.2.10" on the first machine returns:

+92 bytes from virtuallfs (10.0.2.9): Destination Host Unreachable
+--- 10.0.2.10 ping statistics ---
+1 packets transmitted, 0 packets received, 100% packet loss
+----
+and something similar when typing "ping -c 1 10.0.2.9" on the second machine.
+
+This very same setting works as expected in version 2.6.0. I could bisect, and the offending commit is 16a3df403b1:

+    net/net: Add SocketReadState for reuse codes
+    
+    This function is from net/socket.c, move it to net.c and net.h.
+    Add SocketReadState to make others reuse net_fill_rstate().
+    suggestion from jason.
+    
+    v4:
+     - move 'rs->finalize = finalize' to rs_init()
+    
+    v3:
+     - remove SocketReadState init callback
+     - put finalize callback to net_fill_rstate()
+    
+    v2:
+     - rename ReadState to SocketReadState
+     - add SocketReadState init and finalize callback
+    
+    v1:
+     - init patch

+BTW, the systems on both VM are built from http://www.linuxfromscratch.org. But I do not think this is important, since I could do the bisect. Of course, I'll be happy to try other VMs, if you point me to some.
+
+The patch for this issue is here:
+
+https://lists.gnu.org/archive/html/qemu-devel/2016-11/msg00811.html
+
+Fix has been committed: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=e79cd4068063ea285919
+
+Great. Thanks to you both.
+
+Fix has been released with QEMU v2.8
