[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
