Setup the KVM Module to allow nested VMs:
[root@house-vscaler nova]# echo "options kvm-intel nested=y" >> /etc/modprobe.d/dist.conf
[root@house-vscaler nova]# cat /etc/modprobe.d/dist.conf
options kvm-intel nested=y
[root@house-vscaler nova]# scp /etc/modprobe.d/dist.conf node01:/etc/modprobe.d/
dist.conf 100% 27 0.0KB/s 00:00
[root@house-vscaler nova]# scp /etc/modprobe.d/dist.conf node02:/etc/modprobe.d/
dist.conf 100% 27 0.0KB/s 00:00
[root@house-vscaler nova]# scp /etc/modprobe.d/dist.conf node03:/etc/modprobe.d/
dist.conf 100% 27 0.0KB/s 00:00
[root@house-vscaler nova]#Then REPEAT on each node (or reboot)
[root@node02 ~]# cat /sys/module/kvm_intel/parameters/nested
N
[root@node02 ~]# modprobe kvm
[root@node02 ~]# modprobe kvm_intel
[root@node02 ~]# cat /sys/module/kvm_intel/parameters/nested
YSetup the kolla environment for nova.conf
[root@house-vscaler ~]# cat /etc/kolla/config/nova/nova.conf
[libvirt]
virt_type=kvm
cpu_mode=host-passthroughReconfigure OpenStack (using Kolla reconfigure)
[root@house-vscaler ~]# source /etc/kolla/admin-openrc.sh
[root@house-vscaler ~]# kolla-ansible -i vscaler/multinode reconfigure
You should end up with this: (fail should be=0 everywhere)
