2.submit job in wlk.
3.during manual testing:
{"execute":"set_link","arguments":{"name":"net1","up":false}}
{"return": {}}

{"return": {}}

Actual results:
job failed.
Error message:
Warning 9/27/2014 12:49:22.265 PM Did not receive the WMI connect event within 300 seconds . This is probably a bug in the NIC driver for Red Hat VirtIO Ethernet Adapter. It may not have indicated the media connect status to NDIS or may not have connected back.
