At the J-PARC Main Ring (MR), we have used virtual-machine environment extensively in our accelerator control. In 2011, we developed a virtual-IOC, an EPICS In/Out Controller running on a virtual machine [1]. Now in 2013, about 20 virtual-IOCs are used in daily MR operation. In the summer of 2012, we updated our operating system from Scientific Linux 4 (SL4) to Scientific Linux 6 (SL6). In the SL6, KVM virtual-machine environment is supported as a default service. This fact encouraged us to port basic control services (ldap, dhcp, tftp, rdb, achiver, etc.) to multiple virtual machines. Each virtual machine has one service. Virtual machines are running on a few (not many) physical machines. This scheme enables easier maintenance of control services than before. In this paper, our experiences using virtual machines during J-PARC MR operation will be reported.
