Thanks Ethan. Core file generation is enabled. However, I do not see
any core files under failed test directory i.e
tests/testsuite.dir/0449. Is the generated core file available in that
directory or some place else? or it could be that ovs-vswitchd didn't
segfault at all?
openvswitch# ulimit -a
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
