Embedded Virtualization Greg Ungerer greg.ungerer@accelerated.com
Embedded Virtualization For development • Run on host as testing tool • Native development platform On target • Fast cheap capable hardware • Multiple machine instances
Embedded Virtualization Advantages/Disadvantages: • Self contained restartable boxes • Combine multiple machines into one • Feature/functionality isolation • Hardware abstraction (“real” hardware) • Resource requirements (RAM/flash/etc)
Embedded Virtualization Software Support: • QEMU • KVM • Libvirt
Embedded Virtualization Building for Target: • Cross compiling • Use of other libc (uClibc, musl, etc) • Other missing libs
Embedded Virtualization Performance: • Slower? • Custom hardware • Driver acess • Acceleration technologies (openvswitch, Intel VT, AMD-V, PCI-SRIOV, DPDK, etc)
Embedded Virtualization Managing Virtual Machines: • Libvirt • Web management • VNC
