The veth device creation code run in two steps, first it looks for two free veth device names, then it runs ip link to create the veth pair. There is an obvious race between finding free names and creating them, when guests are started in parallel. Rewrite the code to loop and re-try creation if it fails, to deal with the race condition.

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.
