Abstract (in Japanese) (See Japanese page) 
(in English) The operation support system (OSS) of the mobile communication network is a large-scale system which monitors various network devices and it has already become an important social infrastructure with the recent spread of smartphones and IoT.
We have succeeded in a cost reduction for system replacement and its operation by introducing hypervisor virtualization technologies and an OpenStack private cloud.
The new system is now stably operating as the result of clarifying problems and restrictions by an investigation in advance.
In this paper, we will introduce knowledge in realization of a stable operation of a large-scale system on OpenStack, and will explain situations and issues in the future operation.
