OUTPUTDIRDESCRIPTIONVirt builder is a tool for quickly building new virtual machines. How To Install Xorg On Centos Commands' title='How To Install Xorg On Centos Commands' />You can build a variety of VMs for local or cloud use, usually within a few minutes or less. Virt builder also has many ways to customize these VMs. Everything is run from the command line and nothing requires root privileges, so automation and scripting is simple. Note that virt builder does not install guests from scratch. It takes cleanly prepared, digitally signed OS templates and customizes them. This approach is used because it is much faster, but if you need to do fresh installs you may want to look at virt install1 and oz install1. The easiest way to get started is by looking at the examples in the next section. How To Install Xorg On Centos Commands' title='How To Install Xorg On Centos Commands' />EXAMPLESList the virtual machines available virt builder listwill list out the operating systems available to install. A selection of freely redistributable OSes is available as standard. You can add your own too see below. After choosing a guest from the list, you may want to see if there are any installation notes virt builder notes fedora 2. Build a virtual machine virt builder fedora 2. Fedora 2. 5 image for the same architecture as virt builder so running it from an i. This will have all default configuration minimal size, no user accounts, random root password, only the bare minimum installed software, etc. You do not need to run this command as root. The first time this runs it has to download the template over the network, but this gets cached see CACHING. The name of the output file is derived from the template name, so above it will be fedora 2. LinuxVMware Tools,. How To Install Xorg On Centos Commands' title='How To Install Xorg On Centos Commands' />You can change the output filename using the o option virt builder fedora 2. You can also use the o option to write to existing devices or logical volumes. As above, but write the output in qcow. GAs above, but the output size will be 2. GB. The guest OS is resized as it is copied to the output automatically, using virt resize1. As above, but using an i. Setting the root password virt builder fedora 2. Create a Fedora 2. The root password is taken from the file tmprootpw. Note if you dont set root password then the guest is given a random root password which is printed on stdout. You can also create user accounts. See USERS AND PASSWORDS below. Set the hostname virt builder fedora 2. When prompted to choose between Try Ubuntu and Install Ubuntu, choose Try Ubuntu because well need to perform a step after the installer. The following simple guide help you to setup the VNC server on RHEL 7CentOS 7 machines, VNC help to share the desktop with the other machines which has a client. Set the hostname to virt. Installing software. To install packages from the ordinary guest software repository eg. Xfce DesktopIn Fedora, is used to install groups of packages. On Debian you would install a meta package instead. To update the installed packages to the latest version virt builder debian 7 update. For guests which use SELinux, like Fedora and Red Hat Enterprise Linux, you may need to do SELinux relabelling after installing or updating packages see SELINUX below virt builder fedora 2. Customizing the installation. There are many options that let you customize the installation. These include run run command, which run a shell script or command while the disk image is being generated and lets you add or edit files that go into the disk image. For example cat lt lt EOF tmpdnf update. Or virt builder fedora 2. You can combine these options, and have multiple options of all types. OPTIONS help. Display help. ARCHITECTUREUse the specified architecture for the output image. This means there must be sources providing the requested template for the requested architecture. See also ARCHITECTURE. ISOFILEDuring the customization phase, the given disk is attached to the libguestfs appliance. This is used to provide extra software repositories or other data for customization. You probably want to ensure the volumes or filesystems in the attached disks are labelled or use an ISO volume name so that you can mount them by label in your run scripts mkdir tmpmount. LABELEXTRA tmpmount. You can have multiple attach options, and the format can be any disk format not just an ISO. See also run, Installing packages at build time from a side repository, genisoimage1, virt make fs1. FORMATSpecify the disk format for the next attach option. The FORMAT is usually raw or qcow. Use raw for ISOs. DIR no cache cache DIR sets the directory to usecheck for cached template files. If not set, defaults to either XDGCACHEHOMEvirt builder or HOME. Download all templates to the cache and then exit. See CACHING. Note this doesnt cache everything. More templates might be uploaded. Also this doesnt cache packages the install, update options. Checkdont check the digital signature of the OS template. The default is to check the signature and exit if it is not correct. Using no check signature bypasses this check. See also fingerprint. Use ANSI colour sequences to colourize messages. This is the default when the output is a tty. If the output of the program is redirected to a file, ANSI colour sequences are disabled unless you use this option. CURLSpecify an alternate curl1 binary. You can also use this to add curl parameters, for example to disable https certificate checks virt builder curl curl insecure. Delete the template cache. See CACHING. no delete on failure. Dont delete the output file on failure to build. You can use this to debug failures to run scripts. See DEBUGGING BUILDS for ways to debug images. The default is to delete the output file if virt builder fails or, for example, some script that it runs fails. AAAA BBBB. Check that the index and templates are signed by the key with the given fingerprint. The fingerprint is a long string, usually written as 1. You can give this option multiple times. If you have multiple source URLs, then you can have either no fingerprint, one fingerprint or multiple fingerprints. If you have multiple, then each must correspond 1 1 with a source URL. For ordinary builds, this selects the output format. The default is raw. With get kernel this specifies the input format. To create an old style qcow. RHEL 6 or very old qemu lt 1. IMAGEThis option extracts the kernel and initramfs from a previously built disk image called IMAGE in fact it works for any VM disk image, not just ones built using virt builder. Note this method is deprecated there is a separate tool for this, virt get kernel1, which has more options for the file extraction. The kernel and initramfs are written to the current directory, unless you also specify the outputoutputdirdirectory name.
