On the host I was trying to put on maintenance:
vdsm-xmlrpc-4.17.28-0.el7.centos.noarch
vdsm-4.17.28-0.el7.centos.noarch
vdsm-infra-4.17.28-0.el7.centos.noarch
vdsm-yajsonrpc-4.17.28-0.el7.centos.noarch
vdsm-python-4.17.28-0.el7.centos.noarch
vdsm-jsonrpc-4.17.28-0.el7.centos.noarch
vdsm-hook-vmfex-dev-4.17.28-0.el7.centos.noarch
vdsm-cli-4.17.28-0.el7.centos.noarch

And it was trying to send to an host with:
vdsm-yajsonrpc-4.17.28-1.el7.noarch
vdsm-cli-4.17.28-1.el7.noarch
vdsm-python-4.17.28-1.el7.noarch
vdsm-hook-vmfex-dev-4.17.28-1.el7.noarch
vdsm-xmlrpc-4.17.28-1.el7.noarch
vdsm-4.17.28-1.el7.noarch
vdsm-infra-4.17.28-1.el7.noarch
vdsm-jsonrpc-4.17.28-1.el7.noarch

And in the log about that:
jsonrpc.Executor/1::DEBUG::2016-06-17 11:39:57,233::__init__::503::jsonrpc.JsonRpcServer::(_serveRequest) Calling 'VM.migrate' in bridge with {u'params': {u
