Hello, I have some difficulties regarding to above title. Windows as guest OS is running on KVM(Ubuntu natty). After attaching LVM volume to guest OS and did "safely remove device" in guest windows, detaching volume was failed. 'virtio-disk2' not found But kvm(qemu?) seems like detaching device successfully. file=/opt/win/win2008server.virtio.img ro=0 drv=qcow2 encrypted=0 So, problem is, libvirt doesn't know detaching, but kvm(qemu) knows. Again, please let me know if anybody has workaround. P.S. at some website, I found "hotunplugging is not supported in current libvirt", is that related on this matter? Regards, mkey
