Using the 'personality(2)' system call, we can make a container on an x86_64 host appear to be i686. Likewise for most other Linux 64bit arches. * src/lxc/lxc_conf.c: Fill in 32bit capabilities for x86_64 hosts * src/lxc/lxc_container.h, src/lxc/lxc_container.c: Add API to check if an arch has a 32bit alternative * src/lxc/lxc_controller.c: Set the process personality when starting guest
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
