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, On Thu, May 12, 2016 at 12:56 AM, Tong Li <liton...@us.ibm.com> wrote: > try with a tiny image and see what you get.
