![]() Unlike libvirt’s destroy or undefine actions, this will (by default) also remove the associated virtual storage files. Once you are done with your VM, you can destroy it with: uvt-kvm destroy secondtest ![]() You can get the list of VMs running on your system with the uvt-kvm list command. See "man sudo_root" for the list of running VMs $ ssh -i ~/.ssh/id_rsa run a command as administrator (user "root"), use "sudo ". The address can be queried using the following command: $ uvt-kvm ip secondtest You can also connect to your VM using a regular SSH session using the IP address of the VM. Once the virtual machine creation is completed, you can connect to it using SSH: uvt-kvm ssh secondtest The uvt-kvm wait command can be used to wait until the creation of the VM has completed: uvt-kvm wait secondttest ![]() If you want to specify a release to be used to create the VM, you need to use the release= filter: uvt-kvm create secondtest release=DISTRO-SHORT-CODENAME This will create a VM named ‘firsttest’ using the current locally-available LTS cloud image. To create of a new virtual machine using uvtool, run the following in a terminal: uvt-kvm create firsttest Your identification has been saved in /home/ubuntu/.ssh/id_rsa. If your environment does not have an SSH key, you can easily create one using the ssh-keygen command, which will produce similar output to this: Generating public/private rsa key pair.Įnter file in which to save the key (/home/ubuntu/.ssh/id_rsa):Įnter passphrase (empty for no passphrase): In order to connect to the virtual machine once it has been created, you must have a valid SSH key available for the Ubuntu user. As an example: uvt-simplestreams-libvirt sync -source A common case is the daily image, which helps you get the very latest images, or if you need access to the not-yet-released development release of Ubuntu. uvt-simplestreams-libvirt sync release=DISTRO-SHORT-CODENAME arch=amd64įurthermore, you can provide an alternative URL to fetch images from. In the case where you want to synchronise only one specific cloud image, you need to use the release= and arch= filters to identify which image needs to be synchronised. Release=focal arch=amd64 label=daily (20191029) Release=bionic arch=amd64 label=daily (20191107) To see what has been downloaded, use the following command: uvt-simplestreams-libvirt query For instance, if you want to synchronise all cloud images for the amd64 architecture, the uvtool command would be: uvt-simplestreams-libvirt -verbose sync arch=amd64Īfter all the images are downloaded from the Internet, you will have a complete set of locally-stored cloud images. It knows where to find the cloud images so only one command is required to get a new cloud image. This is one of the major simplifications that uvtool brings. Get the Ubuntu cloud image with uvt-simplestreams-libvirt This will install uvtool's main commands, uvt-simplestreams-libvirt and uvt-kvm. To install uvtool, run: sudo apt -y install uvtool The following packages and their dependencies will be required in order to use uvtool: uvtool provides a simple mechanism for synchronising cloud images locally and using them to create new VMs in minutes. Starting with 14.04 LTS, a tool called uvtool has greatly facilitated the creation of virtual machines (VM) using cloud images. It is now possible to use those images to create a virtual machine without needing a complete installation. As of 12.04 the use of cloud images outside of a cloud infrastructure has been improved. ![]() With Ubuntu being one of the most used operating systems on many cloud platforms, the availability of stable and secure cloud images has become very important.
