23 Sep 2016 Internals. Design. Cappsule is a small hypervisor (roughly 15K lines of source code) designed for Linux x86-64. It has been heavily tested on Ubuntu 16.04, but any distro with a recent kernel should be able to use it. Since it relies on hardware virtualization, the CPU must support Intel VT-x and EPT. In order
25 Nov 2016 The following instructions will cause VM exit unconditionally: CPUID, INVD, MOV from CR3, RDMSR, WRMSR, and all the new VT-x instructions (which are listed below). There are other . Them xen-unstable tree now includes both intel VT and SVM support, using a common API which is called HVM.
detecting the presence of a VT-x hypervisor. While VT-x offers the possibility to disable traps for some instructions, Intel enforces VM Exits on a selected set of instructions in hardware. We also argue that in order to monitor the guest, the hypervisor has to use some kind of traps, which also gives additional space for evasion.
In computing, x86 virtualization refers to hardware virtualization for the x86 architecture. It allows multiple operating systems to simultaneously share x86 processor resources in a safe and efficient manner. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the
