You can start an instance from an instance snapshot. You can observe OpenStack instances in vSphere as VMs, but you can only manage them in OpenStack.
Before you begin
Verify that you have configured images, flavors, block storage, and networks, and that they are available.
- Log in to the VMware Integrated OpenStack dashboard.
- Select the project from the drop-down menu in the title bar.
The Images page lists the snapshots available to the current user.
- In the Actions column of the snapshot, click Launch.
- On the Details tab of the Launch Instance dialog box, configure the instance.
By default, this value is set to the availability zone that the cloud provider provides, for example, nova.
Assign a name to the VM. This value is a label and is not validated. When you create an instance, a UUID is assigned to the instance. When you view the VM in vSphere, you can identify it by the UUID but not by the instance name.
Specify the size of the instance to start. The cloud administrator defines and manages flavors .
To start multiple instances, enter a value greater than 1. The default is 1.
Instance Boot Source
Select Boot from snapshot, and select the snapshot from the list.
- On the Access & Security tab of the Launch Instance dialog box, configure access and security parameters by specifying a key pair and security group.
Specify a key pair.
If the image uses a static root password or a static key set, you do not need to provide a key pair to launch the instance. A best practice is to use a key pair.
Select the security groups to assign to the instance.
Security groups are sets of rules that determine which incoming network traffic is forwarded to instances. If you did not create security groups, you can assign only the default security group to the instance.
- On the Networking tab of the Launch Instance dialog box, click the + icon in the Available Networks field to add a network to the instance.
- (Optional) : On the Post-Creation tab, specify a customization script that runs after the instance starts.
- In the Advanced Options tab, select the type of disk partition from the drop-down menu.
The entire disk is a single partition and automatically resizes.
Enables faster build times but requires manual partitioning.
- Click Launch.
The new instance starts on a node in the Compute cluster.
- To view the new instance, select
The Instances tab shows the instance name, its private and public IP addresses, size, status, task, and power state.
