Selective Dynamic Analysis of Virtualized Whole-System Guest Environments
… of execution overhead. DECAF extends the mature QEMU whole-system emulator, a type-2 hypervisor capable of emulating every instruction that executes within a complete guest system environment.</p> <p>DECAF provides a novel, hardware event-based method of just-in-time virtual machine introspection …

On Optimizing and Leveraging Distributed Shared Memory for High Performance, Resource Aggregation, and Cache-coherent Heterogeneous-ISA Processors
… instances of an architecture emulator such as QEMU to execute in a shared address space, allowing multiple QEMU instances to emulate different ISAs in shared memory, i.e., emulate shared memory heterogeneous-ISA hardware. PopHype also includes a modified QEMU to use process-level DSM and an …

A Full System Co-Simulation Platform for Evaluating Edge Machine Learning Inference Using Compute-in-Memory
… this gap, we develop an integrated RISC-V QEMU-SystemC co-simulation environment that allows standard embedded Linux to interact with a transaction-level CIM accelerator model via memory-mapped I/O, direct memory access (DMA), and interrupts. To evaluate performance, we benchmark an MNIST …

Clouds of glass: fragility of virtual machine disk images
… Using the virtual machine software QEMU, we show that its qcow2 virtual hard disk format is vulnerable to failures. We then introduce and analyze two alternative solutions to RAID1 (mirror) that use less disk space and are more convenient to use. As a baseline, the qcow2 format is …

HetMigrate: Secure and Efficient Cross-architecture Process Live Migration
… (e.g. Cloud Lab), local setups virtualized with QEMU/KVM, and a server-embedded board pair. Similar to works in the past, we also evaluated the energy and throughput benefits that heterogeneous-ISA systems can offer by connecting a Xeon server to three embedded boards over the network. We …

Exploitation from Malicious PCI Express Peripherals
… by using a device model extracted from the QEMU emulator. We discovered a number of vulnerabilities in the PCIe protocol itself, and with the way that the defence mechanisms it provides are used by modern OSs. The principal defence mechanism provided is the Input/Output Memory Management …

Efficient Virtual Cache Coherency for Multi-core Systems and Accelerators
… dynamic binary translation (DBT), such as QEMU. The second contribution is a collection of open-source processor and system-on-chip (SoC) components, called Muntjac. Muntjac contains implementation of a RISC-V (RV64GC) core with machine and supervisor privilege levels, as well as cache …
