+New default network card doesn't work with tap networking
+
+Unfortunately, I can provide very little information.
+
+Hope this will be useful anyway.
+
+I've upgraded qemu using debian apt to lastest unstable (QEMU PC emulator version 0.12.4 (Debian 0.12.4+dfsg-2), Copyright (c) 2003-2008 Fabrice Bellard): looks like at some point the default network card for -net nic option was switched to intel gigabit instead of the good old ne2k_pci.
+
+I was using -net tap -net nic options and my network stopped working.
+When not working,
+- tcpdump on the host shows me taht all packets are sent and received fine from guest
+- tcpdump on guest shows that packets from host are NOT received
+
+obviously, both host tap interface and guest eth0 interfaces, routing tables, dns, firewall, etc... are well configured.
+
+Having banged my head for a while, I finally stopped the host and started it again using -net nic,model=ne2k_pci option, then my network magically started working again.
