For the past few months we have been working hard to provide a fast, reliable and secure KVM backend for VirtualBox. VirtualBox is a multi-platform Virtual Machine Monitor (VMM) with a great feature set, support for a wide variety of guest operating systems, and a consistent user interface across different host operating systems.
Cyberus Technology’s KVM backend allows VirtualBox to run virtual machines utilizing the Linux KVM hypervisor instead of the custom kernel module used by standard VirtualBox. Using KVM comes with a number of benefits.↫ Florian Pester, Markus Partheymüller
Excellent news. Dealing with the VirtualBox and VMware kernel modules can be a hassle if you’re using newer or custom kernels, and having the VirtualBox UI for kvm instead of things virt-manager is not something I’m unhappy about.
