For the boot failure case, I take more looks into it. I open the trace output and see the following when boot failedHi,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=2048And 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?
Balloon driver, built on Oct 13 2011 10:46:59 ^M<-- DriverEntry ^Mfile z:\source\kvm-guest-drivers-windows\balloon\sys\driver.c line 151 ^M--> BalloonDeviceAdd ^M<-- BalloonDeviceAdd ^M--> BalloonEvtDevicePrepareHardware ^M<-> Port Resource [0000C0A0-0000C0C0] ^M<-- BalloonEvtDevicePrepareHardware ^M--> BalloonEvtDeviceD0Entry ^M--> BalloonInit ^M--> VIRTIO_BALLOON_F_STATS_VQ ^M<-- BalloonInit ^M--> BalloonInterruptEnable ^M<-- BalloonInterruptEnable here, the system is blocked.I compare it with the logfile in the normal case that I hot-plugin the balloon device, and then find the system blocked before calling at BalloonInterruptDpc.
Is it meaning that we open the interrupt of balloon device too soon when booting the system?
