There is very little information in this bug report, like what release
of nova are you using? What's the env topology? There is obviously a
mysql connection failure, so you should probably investigate the mysql
deployment / config / logs as that's what nova is failing on:
2016-11-16 19:44:18.958 2762 ERROR nova.api.openstack.extensions raise
err.OperationalError(2006, "MySQL server has gone away (%r)" % (e,))

OperationalError: (pymysql.err.OperationalError) (2006, "MySQL server has gone
away (error(32, 'Broken pipe'))")
