A lot of the research on this is dedicated to detecting so-called “blue pill” attacks, that is, a malicious hypervisor that is actively attempting to evade detection. The classic trick to detect a VM is to populate the ITLB, run an instruction that must be virtualized (which necessarily clears out such processor state when it … Read more
You can just pause the VM and make a copy the VM folder.
Emulation and virtualization are related but not the same. Emulation is using software to provide a different execution environment or architecture. For example, you might have an Android emulator run on a Windows box. The Windows box doesn’t have the same processor that an Android device does so the emulator actually executes the Android application … Read more
Kill the VBoxHeadless process and run “vagrant destroy” Destroying vagrant and sending the kill signal with the “killall” command looks like: killall -9 VBoxHeadless && vagrant destroy
QEMU is a powerful emulator, which means that it can emulate a variety of processor types. Xen uses QEMU for HVM guests, more specifically for the HVM guest’s device model. The Xen-specific QEMU is called qemu-dm (short for QEMU device model) QEMU uses emulation; KVM uses processor extensions (HVM) for virtualization. Both Xen and KVM … Read more
VMDK/VMX are VMWare file formats but you can use it with VirtualBox: Create a new Virtual Machine and when asks for a hard disk choose “Use an existing hard disk” Click on the “button with folder and green arrow image on the combo box right” which opens Virtual Media Manager, it looks like this (you … Read more
