- * All parameters are in MBytes
+ * @param pm Physical machine that will host the VM
+ * @param net_cap Maximal bandwidth that the VM can consume (in MByte/s)
+ * @param disk_path (unused) Path to the image that boots
+ * @param disksize (unused) will represent the size of the VM (will be used during migrations)
+ * @param mig_netspeed Amount of Mbyte/s allocated to the migration (cannot be larger than net_cap). Use 0 if unsure.
+ * @param dp_intensity Dirty page percentage according to migNetSpeed, [0-100]. Use 0 if unsure.
