The Hyperthreading technology has been introduced to enhance CPU resource utilization so as to increase overall system performance. We briefly present this technology and evaluate its impact on CPU performance by means of a small test series. On the software side, VMware is becoming increasingly of interest in the private and professional sectors, allowing the installation of various operating ...

Tujuan dari penelitian ini adalah untuk mengetahui mesin virtual mana yang lebih bagus dan kecil penggunaannya diukur dalam kinerja memory, disk, CPU setelah dibangun web server mail server, serta kualitas jaringan masing-masing virtualisasi parameter jaringan. Penelitian menggunakan pendekatan kuantitatif dengan deskriptif. Dalam dibandingkan dua software yaitu Proxmox versi 6.0 VMware ESXi 6....

Virtual machines were developed by IBM in the 1960’s to provide concurrent, interactive access to a mainframe computer. Each virtual machine is a replica of the underlying physical machine and users are given the illusion of running directly on the physical machine. Virtual machines also provide benefits like isolation and resource sharing, and the ability to run multiple flavors and configurat...

The IT center of Kuwait Oil Company (KOC) is one of the largest information centers in the State of Kuwait. It provides many services to KOC departments and other Kuwait oil sector companies (K-Companies). These services need to ensure High Availability (HA) and flexibility in their operations. The aim of this paper is to investigate the impact of the damage that affects the Business Continuity...

Virtualization is becoming increasingly popular, both for servers as well as desktop systems. It is a core technology of the IT applications such as green IT and cloud computing. Operating system which directly communicates with system hardware is host operating system and Operating system which runs on hypervisor type-2 is guest (virtual) operating system. Performance of the guest (virtual) op...

This work exposes further vulnerabilities in virtualized cloud servers by mounting Cross-VM cache attacks in Xen and VMware VMs targeting AES running in the victim VM. Even though there exists a rich literature on cache attacks on AES, so far only a single work, demonstrating a working attack on an ARM platform running a L4Re virtualization layer has been published. Here we show that AES in a n...
