Hi, I encounter a problem. My virtual machine is windows 7 . I install it using bus ide. There is not any problem until now. but when I want to attach a disk to it(bus=scsi ) , the os can’t find the suitable SCSI driver. I search the problem on the internet ,it seems that the windows7 don’t support SCSI driver. So ,I want attach the disk to vm using SATA. So I want to know that whether the kvm support SATA driver and whether the kvm support USB 2.0? Hope for reply. Thank in advance.
