/etc/nova/nova-compute.conf configuration file
Compute_driver=libvirt. Libvirtdriver
[Libvirt]
Virt_type=qemu

If you cannot use VIRT_TYPE=KVM in a virtual machine environment

Compute_dirver should be replaced

#compute_driver =libvirt. Libvirtdriver

Compute_driver=nova.virt.libvirt.libvirtdriver

Next you will be prompted for a firewall error

Error message:

"Attributeerror: ' Module ' object has no attribute ' noopfirewalldriver ' \ n

The reason is: in the configuration file

Firewall_driver=nova.virt.libvirt.firewall.noopfirewalldrive

Replaced by

Firewall_driver=nova.virt.firewall.noopfirewalldrive

6.openstack command not available?

Yum Install Python-openstackclient

7. Control node Execution neutron agent-list error

Unable to establish connection to Http://controller:9696/v2.0/agents.json

8. Time Out of sync causes neutron ageng-list xxx problem

Synchronize the time between nodes to be able

9.compute node Error

Connectionrefused:unable to establish connection to Http://controller:35357/v2.0/tokens

Because the firewall on the control node is causing the firewall to Systemctl stop Firewall.service

10.VNC connection Virtual machine failure reason

Because the firewall on the compute node does not release the 5900+ port
