[Qemu-devel] balloon driver on winxp guest start failed

[hkran]

Hi,

I used balloon driver for windows  virtio-win-0.1-15.iso (from 
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/)

following the install guard , I installed the balloon driver like this:

devcon.exe install d:\wxp\x86\balloon.inf 
"PCI\VEN_1AF4&DEV_1002&SUBSYS_00051AF4&REV_00"
 then reboot guest Os, but the status of driver installed is always 
incorrect, that show me the driver start failed (code 10) in the device 
manager.

I typed the following cmds in the monitor command line:

(qemu) device_add virtio-balloon
(qemu) info balloon
balloon: actual=2048
(qemu) balloon 1024
(qemu) info balloon
balloon: actual=2048
(qemu) info balloon
balloon: actual=2048

And I also tried it by using "qemu -balloon virtio" param  when getting 
qemu up, the status is worse, the winxp guest froze at boot screen.

Am I using balloon driver in a correct way?
