Hello,
I've been following the various instructions I've found on the web in an
attempt to get tap networking with qemu-devel-0.9.0s.20070802 and
kqemu-kmod-1.3.0.p11_2 on 6.2-STABLE.
qemu was compiled with:
_OPTIONS_READ=qemu-devel-0.9.0s.20070802
WITH_KQEMU=true
WITHOUT_HACKS_CIRRUS=true
WITHOUT_RTL8139_TIMER=true
WITHOUT_SAMBA=true
WITH_SDL=true
WITH_CDROM_DMA=true
The kernel modules are loaded:
if_tap, bridge, aio, kqemu
The sysctls are changed:
sysctl net.link.ether.bridge_cfg=ath0,tap0
sysctl net.link.ether.bridge.enable=1
The tap device exists:
crw------- 1 root wheel 0, 134 Sep 19 22:42 /dev/tap0
tap0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 0.0.0.0 netmask 0xff000000 broadcast 0.255.255.255
ether 00:bd:01:3c:01:00
Opened by PID 1317
The qemu-ifup script exists:
cat /etc/qemu-ifup
#!/bin/sh
ifconfig ${1} 0.0.0.0
I launch qemu like this:
qemu -m 512 -localtime -hda VMs/w2k3.img -net nic -net tap
Windows Server 2003 comes up. If I attempt to use DHCP to configure the
interface in W2K3, I get a several minute pause while it attempts to
contact a DHCP server, finally it fails with the message:
"This connection has limited or no connectivity"
and windows assigns itself the 169.254.244.101 address.
If I try to manually configure the windows interface, i.e.,
IP: 172.16.1.15
NM: 255.255.255.0
DG: 172.16.1.1
NS: 172.16.1.17
NS: 172.16.1.21
Windows thinks it has connectivity, but I cannot ping the default
gateway from the guest and I cannot ping the IP of the guest from the
host.
So at this point, I have no networking from the guest OS. About the
only thing that I haven't seen on the web is people using wireless NICs
in the host. In my case, I have an atheros chipset connected via WPA2
to my WAP.
All help is appreciated...

Doug
