	J-PARC accelerator complex comprises Linac, 3-GeV RCS (Rapid Cycle Synchrotron), and 30-GeV MR (Main Ring). The J-PARC is a joint project between JAEA and KEK. Two control systems, one for Linac and RCS and another for MR, were developed by two institutes. Both control systems use the EPICS toolkit, thus, inter-operation between two systems is possible. After the first beam in November, 2006, beam commissioning and operation have been successful. However, operation experience shows that two control systems often make operators distressed: for example, different GUI look-and-feels, separated alarm screens, independent archive systems, and so on. Considering demands of further power upgrade and longer beam delivery, we need something new, which is easy to understand for operators. It is essential to improve reliability of operation. We, two control groups, started to discuss future directions of our control systems. Ideas to develop common GUI screens of status and alarms, and to develop interfaces to connect archive systems to each other, are discussed. Progress will be reported.

	The control system for J-PARC accelerator complex has been developed based on the EPICS toolkit. About 100 traditional ("real") VME-bus computers are used as EPICS IOCs in the control system for J-PARC MR (Main Ring). Recently, we have introduced "virtual" IOCs using Xen, an open-source virtual machine monitor. Scientific Linux with an EPICS iocCore runs on a Xen virtual machine. EPICS databases for network devices and EPICS soft records can be configured. Multiple virtual IOCs run on a high performance blade-type server, running Scientific Linux as native OS. A few number of virtual IOCs have been demonstrated in MR operation since October, 2010. Experience and future perspective will be discussed.
