Re: Does anyone successfully use USB drive in Windows7 guest?

I can't use PCI passthrough feature to pass the whole USB controller to VM, because the hypervisor also needs to use some USB ports. If I use Windows XP or Linux, the USB drive can work well. Try the following when starting qemu-kvm. Replace sdX with your USB device. ... -device usb-ehci,id=ehci \ -drive if=none,id=usbstick,file=/dev/sdX \ -device usb-storage,bus=ehci.0,drive=usbstick \ ... If would like to add the device while your VM is running, you may omit the last two lines and add this one instead: -monitor telnet:127.0.0.1:1,server,nowait,nodelay Add the device using the two commands below: echo "drive_add 0 id=usbdrive,if=none,file=/dev/sdX"| /bin/nc -w1 127.0.0.1 1 echo "device_add usb-storage,id=usbdrive,bus=ehci.0,drive=usbdrive"| /bin/nc -w1 127.0.0.1 1 Remove the device by first ejecting the USB drive under Win7. Then use this line to remove the drive from the VM: echo "device_del usbdrive"| /bin/nc -w1 127.0.0.1 1 Regards André -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Does anyone successfully use USB drive in Windows7 guest? If I pass a USB drive to Windows7 guest, Device Manager may find this device but the USB mass storage driver can't be installed successfully. I have tried many times. Is the emulated USB controller is so old and Windows7 doesn't support it? I can't use PCI passthrough feature to pass the whole USB controller to VM, because the hypervisor also needs to use some USB ports. If I use Windows XP or Linux, the USB drive can work well. I think it's because qemu/kvm does not support USB 2.0. http://wiki.qemu.org/Planning/0.15 -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
