Kirk Kosinski commented on CLOUDSTACK-3482:
-------------------------------------------

I don't this is a CloudStack issue. After following the steps above, attempting to detach
the volume via XenCenter also fails. If the volume is attached at VM boot it is considered
in use and the following is seen in xensource.log:

[20131001T23:39:59.873Z|error|xenserver-vs01|51421 inet-RPC|VBD.unplug R:98e8244db6a5|xapi]
Xapi_vbd.destroy_vbd got an error (frontend (domid=3 | kind=vbd | devid=51728); backend (domid=0
| kind=vbd | devid=51728)) 16 Device in use; refusing to close

And in /var/log/messages in the VM:

Oct  1 23:39:59 vm2 kernel: vbd vbd-51728: 16 Device in use; refusing to close
