<font size="2" face="sans-serif"> I don't have a real PC to so created a test env ,so I created a 2nd level env (create a kvm virtual machine on top of a physical host then run devstack o the vm)</font><br>
<font size="2" face="sans-serif"> I am not sure whether it's doable because I saw following error when start nova-compute service , is it a bug or I need to update my configuration instead? thanks </font><br>
