Hello guys, I'm getting problems when trying to migrate a VM.


I'm getting this error on my log:

Thank you.

Hello Wangpan, I've looking at the logs and I saw one error with my ssh port, and then I fixed the port, but now I'm getting this error:

What "host key verification"? Where should I put this key?


Thank you.

I've done chmod 777 -R /var/log/nova/instances 


Does it work?



2013/7/24 Wangpan <hzwangpan@xxxxxxxxxxxxxxxx>

I saw this error "Permission denied: '/var/lib/nova/instances/'" in your logs.
you may need to chown the instances path  '/var/lib/nova/instances/'
