udev device naming

Hello All, I have a virtual machine to which I dynamically attach/detach disk devices. On this VM the boot device is always '/dev/sda'. When a attach and detach different disk continuously to this virtual machine, every-time, the same device file '/deb/sdb' is created. Is there anyway I can tell
