           Summary: Win Vista and Win2K8 guests cann't find NIC driver
           Product: Virtualization
           Version: unspecified
    Kernel Version: 3.0.0-rc6+
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: kvm
        AssignedTo: virtualization_kvm@kernel-bugs.osdl.org
        ReportedBy: yongjie.ren@intel.com
                CC: kvm@vger.kernel.org
        Regression: Yes


Win Vista and Win 2K8 guests cannot find NIC driver using latest kvm upstream
tree. (I've installed these NIC drivers in the win imgages, and they worked
well before.)
Windows XP doesn't have this this issue.
Both UP and SMP guests have the same issue.
Both virtual NIC and VTD NIC have the same issue, but SR-IOV NIC doesn't have
this issue.
Linux guest doesn't have this issue.

reproduce steps:
1.install qemu-kvm and kvm(e2dd78cba341fa7f4d2aa2a3f2a5ec48615155ad)
2.create a win2k8 or Vista guest: 
qemu-system-x86_64  -m 1024 -smp 2  -net
nic,macaddr=00:16:3e:41:50:cc,model=rtl8139 -net tap,script=/etc/kvm/qemu-ifup
-hda /root/win2k8.img
3.In guest, you'll find that NIC driver cannot be available. In device manager,
it shows the NIC doesn't have the corresponding driver. And 'ipconfig' command
shows nothing.

BTW,
e2dd78cba341fa7f4d2aa2a3f2a5ec48615155ad commit has the issue;
but e62c2ef9d55731476d5783b06c93976c70b96afa commit doesn't have this issue.
