+ * @vm: domain object
+ * @disk: index of disk to check
+ * @cold_boot: true if a new VM is being started
+ *
+ * This function should be called when the source storage for a disk device is

+ * removal of the source (or disk) according to the state of the VM.
+ *
+ * The function returns 0 if the source or disk was dropped and -1 if the state
+ * of the VM does not allow this. This function does not report errors, but
+ * clears any reported error if 0 is returned.
