[libvirt] A problem about libvir

Hello, I have a problem for help. I use the libvir library 0.4.2 on Xen 3.2.0, the host OS is Suse 10.2 . I start a windows domain (windows xp). I use the function virDomainAttachDevice() to attach an iSCSI device to the windows domain,but it failed. I can use this function to attach an iSCSI device to a linux domain. How can I attach an iSCSI device to a windows domain ? or libvir doesn't support attach device to windows domain ? thanks a lot! MOBILE: 13622388220 HUAWEI TECHNOLOGIES CO.,LTD.
