First, we need to understand that creating a virtual machine using the nova command line requires the following information:
GlanceID, flavorID, net-id, security-groupsID, availability-zone (specified parent machine}, keypairname
1. View glance
Use the command: glance image-list to list all the image on the node and select the desired image. Here we choose: 93449941-fba1-436e-a4f2-74a5c1250ad1
2. View flavor
Use the command: nova flavor-list to list all the flavor on the node, select the desired flavor, and we choose m1.smal here.
3. View the network id
(1): use the command: nova network-list can list all current networks. What we choose here is: 006f71f5-a26e-4040-9c12-67cafab70936 | net59
(2): use the command: neutron net-list | grep net59 to know more clearly the IP segment of the virtual machine we created.
4. View security groups
Generally, the security group is set to default, but sometimes it may not be necessary, so we need to check it and then make a choice. Command: nova secgroup-list
What you get here is: 457554a3-20fb-45b3-80af-f15c9d74613b
5. Obtain keypair
