Optimizing I/O performance in ViMo-S hypervisor with zero-copy method
Pages 50 - 54
Abstract
ARM CPU is expanding into server market with the introduction of virtualization extensions. Virtualization is one of the key technologies that is commonly employed in servers. Virtualization is provided by hypervisor and ViMo-S is a prototype hypervisor specifically designed for ARM servers supporting full virtualization. I/O performance is one of the main challenges in hypervisor implementation. In this paper we will explain how we optimize I/O performance in virtual machines of ViMo-S hypervisor with zero-copy method. Through rigorous performance comparison between virtual machine running with zero-copy and virtual machine without zero-copy, we note that zero-copy method have increased block device's transaction-efficiency by up to 25.4% and transfer-efficiency by 31.5%.

My VM is Lighter (and Safer) than your Container
SOSP '17: Proceedings of the 26th Symposium on Operating Systems PrinciplesContainers are in great demand because they are lightweight when compared to virtual machines. On the downside, containers offer weaker isolation than VMs, to the point where people run containers in virtual machines to achieve proper isolation. In this ...
