Open Stack

thanks.
No, i am not even able to create instance using tiny flavor as well. before
integrating Ironic service , i was able to create instances and it was
working fine. issues stared coming when ironic came into the picture.
as i mentioned earlier, i have two compute nodes .. one for VMs and one for
baremetal.
now i dont know which compute host has the issue

should i host the nova.conf file somewhere so that you can review ?
Regards,
