[Error message] error: Failed to start domain lxc_test1 error: internal error Failed to create veth device pair: 512 The reason of the failure is that lxc driver unexpectedly re-uses an auto-assigned veth name and tries to create the created veth again. The failure will happen when a domain has multiple network interfaces and the names of those are not specified in XML. The patch fixes the problem by resetting buffers of veth names in every iteration of creating veth. * src/lxc/lxc_driver.c: prevent re-using auto-assigned veth name Reported by Kumar L Srikanth-B22348.
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.
