KVM-17 & WinXP network setup hangs

["Alessandro Sardo" <sandro.sardo-8RLafaVCWuNeoWH0uzbU5w@public.gmane.org>]

Hello KVM devs,

I've just downloaded and checked out KVM-17. I tried 
installing a Windows XP SP2 guest, using the following 
script (notice how I did NOT use the '-no-acpi' flag):

qemu -hda /var/vm/img/WinXP.img -cdrom 
/var/vm/iso/WinXP.iso -boot d -m 512

The first phase of installation went straight without any 
problem - and it was quite faster than previous releases! 
Then, when the guest had to reboot, KVM crashed with the 
following output:

Not a big problem though, I just manually restarted it and 
kept going on with the second phase of the installation.

This is where I got the big problem: after installing the 
devices and asking for the cd-key (among other things), 
the guest totally *stalled* while configuring the network. 
It just says "Installing the network...", but the progress 
bar is frozen - and there's no output on the shell. I've 
also tried with the '-net nic,model=rtl8139' flag, but the 
result was the same. I'm unable to complete the 
installation.

Is there a work-around for this?

Thanks!
