[Qemu-devel] windows guest virtio serial and balloon driver test issues

[Cao,Bing Bu]

Hi,

    Recently,I am testing windows guest driver on Win7 and WinXP(32bit) 
with the latest windows guest driver development source.
    Download from 
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/src/


virtio-blk:
    It seems OK both on Win7 and WinXP,the r/w performance is better 
than IDE disk.



virtio-serial:
    I tried to test virtio serial driver using the test application in 
the project.

    WinXP:
    Write: OK
    Read: Error: Read File Failed.

    Win7:
    The test application return error "can not find vioserial device".
    But i debug the code and check that the GetDevicePath() return 
value is not NULL,and same as the value when testing on WinXP.
    Why the CreateFile() in init() not called? (:


virtio-balloon:

    QEMU monitor: device_add virtio-balloon-pci

    On the guest,a new device "PCI standard RAM controller" added.
    But the Device Manager prompt "No driver installed for this 
device", but install the driver "balloon.sys" failed.
    It said the driver is up to date.    Confused. (:

    How can I install and test the balloon driver on Windows?



The kvm-guest-drivers-windows.git on kernel.org is not available,is 
there any mirror git repository?
Any mail-list or bugzilla for windows guest driver?

Any help from will be appreciated.
