Xen devel - Jul 2010 - Need help to get networking to work in WinXP domU

Hi all,

I am running a WinXPsp3 domU in Xen-4.0.1-rc5-pre x86_64 environment, but
with no network interface enabled. The only way I could get the domU to boot
successfully was when I commented out the vif line in the win.hvm config
file (see attached win.hvm, which is based on /etc/xen/xmexample.hvm).
Also attached are few other log files (xend.log and
qemu-dm-WinXPDomain.log).
Any help on what might be going wrong, and how I can enable networking in
the guest will be much appreciated.
Dom0 has full networking capability though.

Thanks in advance,
Jon

The log says:

domid: 16
warning: could not open /dev/net/tun: no virtual network emulation
Could not initialize device ''tap''

If you google for this you find hints about checking what
''dev/net/tun''
is. And some of them might mention to do ''modprobe tun''.

Say 

linux-y4jf:~ # brctl show
bridge name    bridge id        STP enabled    interfaces
br0        8000.90e6ba2d11eb    no        eth0

and vif =[''type=ioemu, bridge=br0'' ] is included in win.hvm.

What output you get to screen and logs ?
Isn''t it "Hotplug scripts fail to work" ?

Boris.
