SLIDE 2

Embedded Virtualization

For development

Run on host as testing tool
Native development platform

On target

Fast cheap capable hardware
Multiple machine instances

SLIDE 3

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)

SLIDE 4

Embedded Virtualization

Software Support:

QEMU
KVM
Libvirt

SLIDE 5

Embedded Virtualization

Building for Target:

Cross compiling
Use of other libc (uClibc, musl, etc)
Other missing libs

SLIDE 6

Embedded Virtualization

Performance:

Slower?
Custom hardware
Driver acess
Acceleration technologies

(openvswitch, Intel VT, AMD-V, PCI-SRIOV, DPDK, etc)

SLIDE 7

Embedded Virtualization

Managing Virtual Machines:

Libvirt
Web management
VNC
