Unable to launch CoreOS VM using `corectl`

[asridharan]

I am using corectl HEAD:

corectl version

Server:
 Version:	0.7.18-19-g074c74
 Go Version:	go1.8
 Built:		Mon Oct 23 11:34:12 PDT 2017

Client:
 Version:	0.7.18-19-g074c74
 Go Version:	go1.8

 suggested version is 0.7.18

I was able to download the CoreOS image, but the VM itself doesn't bootup. These are the logs for the CoreOSVM boot logs:
