It is necesssary to unoptimize qemu. Attached is a patch for it and pcnet  I
used.

Qemu is 0.7.0 and a patch is from your post.

Apply attatched patch and ./configure --target-list=i386-softmmu and make.

I used RedHat 7.2 guest but I think it is the same as Linux. When I used
dhcpcd, the program break without messages so that I disabled DHCP client
and set IP address manually

# modprobe pcnet32
# ifconfig eth0 10.0.2.15
# ping 10.0.2.2

Then the program stops with segment fault and get backtrace.

This patch probably works on Linux. Please try to see differences between on
Linux and on Windows if you can.
