Xen-Cap: A Capability Framework for Xen
Hypervisors provide strong isolation and can be leveraged to disaggregate large software stack of a traditional, monolithic system. Disaggregation can be achieved by running individual applications and kernel components in separate VMs. Existing hypervisors, however, do not offer a fine grained access control mechanism. Without such mechanism, individual VMs still run in one of two extremes—com...
متن کاملRT-Xen: Towards Real-time Hierarchical Scheduling in Xen
Recent years have seen significant demand for supporting real-time systems in virtualized environments as system integration become an increasingly important challenge for complex real-time systems. This paper presents RT-Xen, the first hierarchical real-time scheduling framework for Xen, the most widely used open-source virtual machine monitor (VMM). RT-Xen bridges the gap between hierarchical...
متن کاملDeconstructing Xen
Hypervisors have quickly become essential but are vulnerable to attack. Unfortunately, efficiently hardening hypervisors is challenging because they lack a privileged security monitor and decomposition strategies. In this work we systematically analyze the 191 Xen hypervisor vulnerabilities from Xen Security Advisories, revealing that the majority (144) are in the core hypervisor not Dom0. We t...
متن کاملUsing KVM to run Xen guests without Xen
The inclusion of the Kernel Virtual Machine (KVM) driver in Linux 2.6.20 has dramatically improved Linux’s ability to act as a hypervisor. Previously, Linux was only capable of running UML guests and containers. KVM adds support for running unmodified x86 operating systems using hardware-based virtualization. The current KVM user community is limited by the availability of said hardware. The Xe...
متن کاملXenITH: Xen in the Hand
Usability and portability have been key commercial drivers for increasingly capable handheld devices, which have been enabled by advances in Moore’s Law and well as in wireless systems. The nature of such devices makes them extremely personal, and yet they offer an untapped resource for new forms of peer-to-peer and cooperative communications relaying. Taking advantage of such capabilities requ...
