Virtual machines

Explore the functionality of the Virtual Machines screen, which provides a comprehensive overview and control of your virtual machines, including creation, management, and monitoring features.

Overview

Navigate to the Virtual Machines overview screen by selecting the 'Virtual Machines' item directly from the left navigation menu. This view will display running and stopped instances.

Creating a new VM

To launch a new Virtual Machine instance, click the 'Create Virtual Machine' button:

Begin by entering a unique name for the instance and highlight the on-demand or reserved resource pool to use (if your tenant has reservations).

Select the operating system type and release version. Denvr Cloud can optionally install current stable releases of GPU drivers and required toolkits.

Finally, choose what types of network attached storage to use with your instance, and paste your SSH public key in the 'SSH Keys' box. Click 'Launch Instance' to begin provisioning.

You will be redirected back to the overview screen where the new VM appears. You will notice the VM status changing as it progresses from PENDING to ONLINE.

Once the Virtual Machine you created reaches ONLINE status, it is ready for use, and you can try pinging it throught the Public IP.

Connect to the instance using your SSH:

$ ssh -i ~/.ssh/id_rsa ubuntu@130.250.171.45

You don't need to provide the -i parameter to SSH if your private key is the default key (id_rsa) or your key is setup in $HOME/.ssh/config file.

You should see output similar to this:

Managing VMs

The main screen for Virtual Machines serves as a control hub, allowing you to start, stop, delete, and view detailed information about each instance.

Use the 3 vertical dots icon next to each VM for lifecycle actions:

• Start - resume a stopped VM

• Stop - stop a running VM. Resources are freed, while the root disk remains persisted

• Delete - fully release a VM. This action can't be undone and removes all instance data

VM details are provided by selecting the instance Name:

Usage metrics

To track the real-time usage of your tenants' virtual machines, explore the 'GPU Utilization' screen. It offers a graphical and tabular representation of your Virtual Machines' usage, providing daily insights and performance data analysis for up to the last two months.

Each utilization record begins at the moment a Virtual Machine is provisioned and continues until the Virtual Machine is stopped, ensuring accurate and continuous tracking of usage.
