VirtMan: design and implementation of a fast booting system for homogeneous virtual machines in iVCE

Zi-yang Li, Yi-ming Zhang, Dong-sheng Li, Peng-fei Zhang, Xi-cheng Lu,ymzhang@nudt.edu.cn

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 2, Pages 110-121 doi: 10.1631/FITEE.1500216

Abstract: has been proposed to combine data centers and other kinds of computing resources on the Internet to provide efficient and economical services. s (VMs) have been widely used in iVCE to isolate different users/jobs and ensure trustworthiness, but traditionally VMs require a long period of time for booting, which cannot meet the requirement of iVCE’s large-scale and highly dynamic applications. To address this problem, in this paper we design and implement VirtMan, a system for a large number of s in iVCE. VirtMan uses the Linux Small Computer System Interface (SCSI) target to remotely mount to the source image in a scalable hierarchy, and leverages the of a set of VMs to transfer only necessary image data at runtime. We have implemented VirtMan both as a standalone system and for OpenStack. In our 100-server testbed, VirtMan boots up 1000 VMs (with a 15 GB image of Windows Server 2008) on 100 physical servers in less than 120 s, which is three orders of magnitude lower than current public clouds.
