[Qemu-devel] [Bug 1404278] [NEW] tap connections not working on windows host

[timsoft]

Public bug reported:

using latest qemu 2.2.0 64bit for windows host (installed from
qemu-w64-setup-20141210.exe obtained from http://qemu.weilnetz.de/w64/
),OpenVPN 2.6.3-I601 64bit tap adapter named tap01 and calling qemu
using the following.

qemu-system-x86_64.exe -m 512 -net nic -net tap,ifname=tap01 -hda
"c:\\data\\images\\test.img"

where the image contains a slackware 14.0 64bit install.
The tap is bridged with the real network adapter and the bridge is given an ip 
of 10.1.1.41 (which works as the ip for the windows host). The tap adapter (in 
network connections) shows connected when the qemu vm is running. inside the 
vm, the network is given an ip of 10.1.1.143 (the netmask and default gateway 
are the same for the virtual and real pc).
fault.
The vm cannot see the rest of the local network or visa-versa. This used to 
work in early (0.9 32bit) versions of qemu.
