Thanks,Frenkel.The test application of the balloon must be run as admin.



But I found 2 problems(question) this week when testing windows guest drivers:



    If only virtio serial driver installed,the virtio serial test app can not enumerate/find the virtio serial device,
    but after virtio balloon driver installed,the app can find the virtio serial device correctly.
    Because of the same GUID which balloon and serial both use?




    When inflate/deflate the balloon size using qemu monitor balloon command,
    the total physical memory did not decrease/increase correspondingly,as seen from "resource monitor",
    only the "available memory" size descrease/increase.But I test on other Linux guest,
    the total physical memory of the guest OS was changed.

    Is it a problem? If not,is it confusing to user?
    Related to the windows internal memory management?

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.



You need to run serial test app as admin only.

To install balloon you have to go throw additional option when click on
"Browse my computer for driver software". Choose "Let me pick from the
list of device drivers on my computer" option.
