First login your VM from console to verify if your VM really gets the IP address you give. If no, it's the network installation/configuration problem. If yes, you can follow the steps in this video "" to troubleshoot it.

Thank you for your answer. The problem is that i can not login my VM, when i start it, i have this error: [end kernel panic - not syncing: VFS: unable to mount root fs onunknown-block (0,0). How can i fix this problem?

Go through google, and you will find a lot of information similar to your problem. Most of them point to a failed installation. Maybe it's caused by your image, not related to OpenStack. Could you give cirros a try?

Hi aisskar,

  1. you are not able to ssh/ping to the instance you created because you may have not set the security group setting do that. enable ICMP and SSH for that instance
  2. for document ion check for devstack guide . for reinstalltion the setps are ./ and ./ if you run these two scripts in your devstack it will clean up the old and setup the new
