instance console got stuck saying : starting up
when i lunch an instance it says successfully complete and says its running but when i switch to console it shows a sentence : starting up my version is newton and im running openstack on vmware workstation
Are you using qemu or KVM? If using qemu with libvirt 2, there is a issue that need to add this at libvirt section in nova.conf
In any case, check nova compute,scheduler abf api logs.
I had the same problem using libvirt 2.0.0 on CentOS 7.3, I've changed the value of cpu_mode parameter in nova.conf from "host-model" to "none" and then the wm boot up successfully. The vm boot from volume using ceph rbd as back end.
Same situation: RDO All-In-One devstack (Newton) on Vmware workstation. Changing cpu_mode from host-model to none solved the problem for newly created VMs.
