[AJNOURI]

RDO All-In-One devstack (Newton) on Vmware workstation.

and the most noticeable log:

for i in ls /var/log/nova/*.log; do tail $i ; echo ""; echo ">>> $i <<<" ;read -p "Press any key..."; done
.

/var/log/nova/nova-manage.log <<<
Press any key...

On the nova host (same as controller):
egrep -c '(vmx|svm)' /proc/cpuinfo
1
So I changed in the file /etc/nova/nova.conf in the section [libvirt]

virt_type = qemu

to

virt_type = kvm

which helped move forward, now it is stuck in

"Booting from Hard Disk ..."
GRUB

#50

[AJNOURI]

/etc/nova/nova.conf
section [libvirt]
Changing cpu_mode from host-model to none
cpu_mode = none
and virt_type back to qemu
virt_type = qemu
solved the problem for newly created VMs.
