KVM & OpenVZ Virtualization And Cloud Computing With Proxmox VE - Page 3

5 Creating OpenVZ Containers

To create an OpenVZ container, go to Virtual Machines > Create...

... and fill in the form. Select Container (OpenVZ) and then the template that you want to use. Specify a hostname (e.g. vm1.example.com), the amount of memory and swap, a root password, select Virtual Network (venet) and specify an IP address for the container (e.g., fill in a VMID, select a cluster node (if you haven't created a cluster (see chapter 3), you can select only the master, not any remote systems), specify if the container should automatically be started when the host boots, and fill in one or two DNS servers (e.g. and Then click on create:

The container is then created...

... and it should be listed on the List tab afterwards. The container is stoppped; to start it, click on the container:

This will open a page where you can control that container. To start it, click on the Start button:

You should then see the link Open VNC console - if you click on it...

... a browser-based console opens from where you can control the virtual machine (this is especially useful for desktop machines; if the virtual machine is a server, you can as well connect to it using SSH (e.g. with PuTTY)).


6 Creating Virtual Machines On Remote Systems In The Cluster

If you've created a cluster (see chapter 3), you can also create virtual machines on remote systems that belong to the cluster - just select a remote node under Cluster Node when you create a virtual machine (the screenshot shows this for OpenVZ, however, this works for KVM guests as well as long as the node supports hardware virtualization):

The List tab should then show that the virtual machine is running on a different node:


7 Creating KVM Guests

If the CPU supports hardware virtualization (Intel VT or AMD-V), you have the possibility to create KVM guests in addition to OpenVZ containers. Just select Fully virtualized (KVM) in the Type drop-down menu, and then either select the cdrom device or one of the ISO images that you've uploaded (if any) from the Installation Media drop-down menu. There are no network settings to be set as this will have to be done directly in the KVM guest. Make sure you select the correct Guest Type (Linux 2.6, Windows XP, etc.):

The KVM guest should be listed on the List tab afterwards; as always with new guests, it is stopped. Click on it...

... to get to its management page; click on the Start button there (if you've selected to install the guest from CD-ROM, please insert the OS CD or DVD into the target system's CD drive before you click on Start):

Then click on the Open VNC console link...

... to connect ot the graphical console of the guest; you should now be able to complete the OS installation just as if it was a physical system:
