Title:
New default network card doesn't work with tap networking
Status in QEMU:
Expired
Bug description:
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.
