1) Authentication

2) check the specifications. The following specifications are available by default.

Because the default image size is incorrect, create a virtual machine and report an error. A new image is uploaded here. For more information, please see "troubleshooting".

Second, create a virtual machine

1) create through the openstack interface

2) View the virtual machine

3) enter the virtual machine operating system through VNC

Third, troubleshooting

1) OpenStack error: Host is not mapped to any cell

Create a virtual machine with the command: Host is not mapped to any cell, and after executing nova-manage cell_v2 discover_hosts-- verbose, you can create a virtual machine.

2) openstack vnc error: failed to connect to server (code: 1006)

Log in to openstack using Firefox in vmware, log in through VNC and report an error failed to connect to server (code: 1006). After adding hostname and IP address resolution to / etc/hosts, you can open VNC.

3) there is a problem with the default cirror image, which causes the creation of a virtual machine to report an error

Troubleshooting idea: at the beginning, creating a virtual machine through the command can run, but creating a virtual machine through the interface reported the error of did not finish being created even after we waited 22 seconds, and it was also wrong to view the disk. I thought that cinder was not configured, but it was normal to create a disk separately. I looked at cinder's log, found lvm': Image is not in qcow2 format, and checked the default mirror. It was found that the mirror was only 4k, while the normal cirros should be about 13m. So upload the new cirros, create the virtual machine again, and the problem is solved.
