Determine whether your compute node supports hardware acceleration for virtual machines:
$ egrep -c '(vmx|svm)' /proc/cpuinfo
If this command returns a value of one or greater, your compute node supports hardware acceleration which typically requires no additional configuration.
If this command returns a value of zero, your compute node does not support hardware acceleration and you must configure libvirt to use QEMU instead of KVM.
Edit the [libvirt] section in the /etc/nova/nova.conf file as follows:
[libvirt]
...
virt_type = qemu

openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu


systemctl enable libvirtd.service
systemctl start libvirtd.service
systemctl enable openstack-nova-compute.service
systemctl start openstack-nova-compute.service
