Start / Stop / Resize VM

This page explains how to manage the lifecycle of a Virtual Machine in CloudRaya, including starting, stopping, and resizing compute resources.

Start and Stop a Virtual Machine

You can start or stop a Virtual Machine using two available methods.

Option 1: From the Virtual Machine List

On the Virtual Machines page, each VM card provides quick action buttons:

• Start – Power on a stopped VM
• Stop – Gracefully shut down a running VM
• Restart VM – Reboot a running VM

These actions are useful for quick operational control without opening VM details.

Option 2: From the VM Detail Page

You can also start, stop, or restart a VM from its detail page:

1. Open Virtual Machines
2. Click View Detail on the selected VM
3. Use the Start, Stop, or Restart VM action buttons at the top of the Overview tab

VM State and Billing Behavior

CloudRaya applies different billing components depending on the current state of a Virtual Machine (VM).
Users can view real-time billing details directly from the VM Detail page.

Billing When a VM Is Running

When a VM is in the Running state:

• Compute resources (CPU and memory) are billed per hour
• Storage resources (root disk and any attached disks) are billed
• Additional components (such as licenses or extra storage) are billed if applicable

On the VM Detail page, the Current Charges section displays the total hourly cost while the VM is active.
This cost reflects all applicable components contributing to the running VM. Click the Current Charges value to see the Charged Detail, a breakdown of the Package Cost and any Additional Cost, such as an OS license or a Public IP.

Billing When a VM Is Stopped

When a VM is in the Stopped state:

• Compute resources (CPU and memory) are not billed
• Storage resources (root disk, additional disks, and snapshots) continue to be billed
• The VM configuration and all data remain intact

In this state, the Current Charges value shown on the VM Detail page is updated automatically.
The displayed hourly cost reflects only the remaining billable components, such as storage or other attached resources.

Billing When a VM is started again:

• The VM resumes using the same configuration
• The public IP address remains the same
• Billing for compute resumes automatically

Resize (Upgrade or Downgrade) a Virtual Machine

Resizing allows you to change the CPU and memory allocation of an existing VM, and to increase its root disk size.

Where to Resize

Resize operations are performed from the VM Detail page:

1. Open Virtual Machines
2. Click View Detail on the VM
3. Go to the Specification tab (you can also click Upgrade in the Specification card on the Overview tab)

The page shows your current configuration, which you can also review by hovering over the Current Specification info icon.

Choose a New Specification

On the Specification tab, you can either:

• Adjust the CPU Core, Memory, and Root Disk sliders to set a custom specification, or
• Choose one of the recommended packages, when available

You can upgrade or downgrade CPU and memory. The Public IP count is not changed on this page, manage Public IPs from the Network tab instead.

Confirm the Resize Operation

After setting your specification or choosing a package:

1. Click Select Package
2. In the confirmation dialog, review your current specification next to the new one, along with the prices that apply to the new specification
3. Type the VM name to confirm
4. Click Upgrade VM to proceed

Resize Behavior and Impact

When resizing a VM:

• The operation can be initiated while the VM is running
• The VM will automatically restart
• Downtime occurs during the restart process
• No data is lost during resizing

Public IP Behavior During Resize

• The VM keeps the same public IP address
• No IP reassignment occurs during resize
• Network configuration remains unchanged

Best Practices

• Perform resize operations during maintenance windows for production workloads
• Take a snapshot before resizing if the VM hosts critical applications
• Remember that root disk size can only be increased, so choose a root disk size you are comfortable keeping
• Monitor application behavior after resizing to validate performance changes
