eSOL has released the 'When and How to Use Virtualization in Embedded Systems Design (and How a Hypervisor Helps)' whitepaper, discussing containers and the four different hypervisor types. Furthermore, a new real-time hypervisor based on an innovative multikernel technology RTOS with POSIX interface is presented. It is also explained how to achieve better performance and freedom from interference (FFI) on multi/manycore hardware.
