Setup ClearOS 7 as ClearVM Guest using ISO

This howto covers installing ClearOS 7 using the ISO image on the ClearOS mirrors. Some information here is useful for installing any operating system where you can see the ISO image on the web.


You should already have your ClearVM server setup and provisioned. You should be able to see your server in the 'Physical Machines' section of the web interface and should have a drive already initialized before continuing.

Adding a Reference ISO to your Store

Navigate to your 'Store' in ClearVM. Here you will see a list of images you can choose from. Scroll all the way to the bottom and click 'Add bookmark'.

In the dialog box, enter ClearOS 7 in the 'Name' section. Check the box that indicates that this is an ISO image. In the 'Image' field, insert the following:
The URL above is the universal/latest ISO image for ClearOS 7 and should not need to be changed throughout the entire release cycle of ClearOS 7

Click the button that indicates that this is 'Linux'. For memory, you should specify at least 1.024 GB (You can allocate more at this time or modify the amount later!) Choose, also, the number of cores and Disk Size you want for your typical installation of ClearOS 7. Remember, this is a template!

Click 'Add'.

From here you will see your entry on your 'Store' under the 'Private' section.

If you need to delete or modify this entry, click the down arrow just to the right of the 'Start' button.

Starting the Installation

To setup and use this image to install ClearOS 7, Click the 'Start' button. Here you will presented with a Dialog box to customize this particular deployment apart from the template configuration. If you want to manipulate the additional paramaters such as Memory and CPU, click the blue field that says 'Mem, CPU, Storage, Net and more'.

For purposes of demonstration, you can see my selections here differ from the template. You must select the Physical Server that you want this to run on. This will limit your allocation of Memory and CPUs. You can also dictate a specific MAC address to use or just use the randomly generated one. The password field is important for management purposes as this is the password that you will use to VNC into the box for remote management. This password is NOT the 'root' password. You will specify that later during the install of ClearOS 7. Make sure to scroll down on this form if you've selected to deviate from the template. You will need to specify the disk and appropriate VLAN. If you are unsure about the VLAN, choose VLAN 0.

When you are done configuring, press the 'Power on' button.

Managing your VM

With your VM powered on, navigate to the 'Machines' tab at the top of the interface, you should see it now listed and running on the left hand navigation screen under the 'Virtual Machines' section. Click on it and you will see a status page for the running VM.

If you click the 'Connect' button in the left hand navigation pane, or if you look in the 'VNC Address' field in the status page, you will see that you can connect using VNC to the virtual machine using a particular address. The colon in the address separates the IP address and the VNC session number. If your VNC client requires port numbers, add the second number to 5900 to find the actual port number. For example, a 1 would be on port 5901.

For security reasons, you need to be on the same network as the ClearVM host in order to manage the virtual machines using VNC.


There are multiple VNC clients that you can use to connect to ClearVM for management of your Virtual machine during installation.


By far, the easiest way to manage launch VNC is from Safari on Mac OSX because VNC is already built in. Simply open a new Safari browser and type in the URL bar the appropriate IP address for your VNC instance. In my case, I'm on session 1 on the IP address listed above.


You can also use full VNC clients such as Chicken of the VNC (now a fork called Chicken) or others. These may have more options which you can use like the ability to switch between virtual screens.


For Windows, you can use TightVNC, TigerVNC, or RealVNC Viewer. You only need the viewer portion of the application. The full blown version will make your local machine also a VNC host.


As with Windows, these VNC applications are also available for Linux. We recommend using one that is turnkey for your Linux distribution.
