The database seems to be unaware that the VM is no more running and hence needs to be synchronised.

First synchronize the database using nova-manage db sync and then reboot the instance. Refer this if you need help for rebooting an instance using nova or you could even use the GUI client: horizon, if you have it installed on your system.

Not work either. The link to http://docs.openstack.org/cli/quick-start/content/nova_client.html (http://docs.openstack.org/cli/quick-s...) is broken (404). Here is the process I went through:

However, that link doesn't work. netstat -pant shows nothing is listening on port 6000. I assume that the warning about the 4 in the database and 0 on the hypervisor is related to my novnc console problem.
