Error seems nova not able to allocate memory to instance as disk file got deleted and fails. So you need to provide required resources, check KVM and restart Nova service before creating instances.

Create the needed resources, then sync with data base after restarting openstack services and sync your database. Then check launching VMs.

I have reinstalled the nova services and Database was resynced even getting the same problem. Check the end to end logs while launching new instance..kindly advise.

Hi Manohar,

Could you check all your nova related services are running fine using nova service-list. Also check the qpidd service is running file.

Since you have deleted the disk file from /var/log/nova/instances/ your instance can't find the bootable disk while spawning. Is it possible to create a fresh instance from image after restarting all the nova related services.?

Your instance id in log (ded56ad8-e5a2-46a6-b62e-c6519d6af402/disk) does not match any instance in the output of nova list.

Run command :

virsh list --all

Check if there is already an instance named "instance-00000002" but not in running status. like this:

 -     instance-00000002              shut off

Remove the instance from libvirt by hand:

virsh managedsave-remove instance-00000002
virsh undefine instance-00000002

This is what exactly I have done, just took the help of google to find the solution. After I use the below commands the disk dependency has been removed to launch new instance. Anyway thanks for the help..
