[Bug 39412] New: Win Vista and Win2K8 guests cann't find NIC driver

[bugzilla-daemon]

https://bugzilla.kernel.org/show_bug.cgi?id=39412

           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.

Driver for Realtek nic (rtl8139) is no longer included in inbox drivers
starting with Windows Vista.

Either use e1000 driver NIC or it is possible to copy related files from the
previous Windows (XP) and use them (inf, sys files).

Guest have driver for the assigned NIC ( If not originally, I installed the
driver), but network in guest breaks down. Sorry for unclear description, and I
modified the bug title. It shows NIC has driver, but network breaks down, for
example guest cannot get IP from the DHCP server. If using kvm.git commit
e62c2ef9, it doesn't have this issue. I use the same win2k8 and Vista image in
my test.
BTW, even if I use e1000 NIC, Win2k8 and Vista guest's network is bad, while
Win7 and Win XP works well.

Please close it, when it hit's Linus tree. In the meantime we leave it as open,
so this doesn't get lost. 

Do you have a pointer to the actual commit that fixed it?

Has the bug been fixed in the mainline kernel?

This bug has been fixed in master tree of kvm.git
Sorry but I don't think I have time to bisect which commit or patch introduced
and fixed this issue very accurately.

As far as I can see, the master branch of kvm.git is based upon v3.0.
In fact none of the 3 commits mentioned above are contained in Linus tree.

Can you please test Linus tree (i.e the mainline kernel, currently at v3.1-rc3)
and verify that it works (or doesn't work)?

RE: [Bug #39412] Win Vista and Win2K8 guests' network breaks down

[Ren, Yongjie]

Hi folks,
I'm the reporter for the bug. Sorry for being late cause I was busy with other stuff.
I only test upstream of Avi's kvm.git and qemu-kvm.git.
>From my test, my automatic test cases for Win Vista and Win2k8 failed at that time. And I also tried this manually, and met the same issue. So I'm sure this was a bug at that time.
Sorry, I don't think I have time to bisect which commit or patch introduced and fixed this issue very accurately.
I can provide some info.

Hi folks,
I'm the reporter for the bug. Sorry for being late cause I was busy with other stuff.
I only test upstream of Avi's kvm.git and qemu-kvm.git.
From my test, my automatic test cases for Win Vista and Win2k8 failed at that time. And I also tried this manually, and met the same issue. So I'm sure this was a bug at that time.
Sorry, I don't think I have time to bisect which commit or patch introduced and fixed this issue very accurately.

Hm ok. But the tree tested by the reporter is contained in kvm/master
and kvm/next and not in Linus tree. 

Anyhow, Rafael did ask the correct question on the bug to resolve
this. :)

Most likely kvm.git got that commit from Linus - I don't think the fix 
came from kvm.git.

I have a truly marvellous patch that fixes the bug which this
