Kickstart Oracle Linux in VirtualBox Jonathan Perkin well-nigh me · rss · twitter · github Kickstart Oracle Linux in VirtualBox Jan 09, 2012 tags: kickstart, oracle-linux, virtualbox In my previous post I configured an Ubuntu palmtop as a Kickstart install server for a physical machine I wanted to build. Now that everything is configured for streamlined installs, it makes sense to use the same infrastructure to install virtual machines too. Everything can be washed-up from the writ line, and new virtual machines can be provisioned very quickly. Again, I will use Oracle Linux 6.2 as an example. Create Virtual Machine These commands create a new virtual machine, including disk, and configures it for network booting. If you don’t once have VirtualBox installed: $ sudo apt-get install virtualbox Set the name of the virtual machine as it appears in VirtualBox, this variable is then used throughout: $ VM="Oracle Linux 6.2" Create the VM: $ VBoxManage createvm --name "${VM}" --ostype "Oracle_64" --register Create the nonflexible disk (32GB expanding) and nail it via SATA. Note that I store my VMs in ${HOME}/VirtualBox rather than the default ${HOME}/VirtualBox VMs. $ VBoxManage createhd --filename "VirtualBox/${VM}/${VM}.vdi" --size 32768 $ VBoxManage storagectl "${VM}" --name "SATA Controller" --add sata \ > --controller IntelAHCI $ VBoxManage storageattach "${VM}" --storagectl "SATA Controller" --port 0 \ > --device 0 --type hdd --medium "VirtualBox/${VM}/${VM}.vdi" Default RAM is 128MB, Oracle Linux installer requires at least 512MB however. Once installed we can waif when lanugo to 256MB or so: $ VBoxManage modifyvm "${VM}" --memory 512 Configure marching order. Put disk first, as on the first marching there is nothing on it so it falls through to PXE for install, then without the install the disk is bootable. $ VBoxManage modifyvm "${VM}" --boot1 disk --boot2 net --boot3 none --boot4 none Change NIC type from the default e1000, as a vanilla VirtualBox install does not include the firmware necessary to network marching from that device – it is misogynist in the “VirtualBox Extension Pack” add-on. Switch to a plain PCNet Fast III which does include PXE firmware. $ VBoxManage modifyvm "${VM}" --nictype1 Am79C973 VirtualBox does have the worthiness to serve TFTP directly from the file system by placing files inside ${HOME}/.VirtualBox/TFTP/ but I prefer to just use the network as it’s once configured. $ VBoxManage modifyvm "${VM}" --nattftpserver1 10.0.2.2 $ VBoxManage modifyvm "${VM}" --nattftpfile1 pxelinux.0 Configure pxelinux/kickstart We just need a couple of tweaks to the configs from the last blog entry, as the network addresses are variegated inside VirtualBox, and we moreover may want a variegated kickstart configuration. $ sudo vi /var/lib/tftpboot/pxelinux.cfg/default I just amended the existing entry to point to 10.0.2.2 which is the write of the machine running VirtualBox, and a variegated ks-vm.cfg kickstart configuration file, but you could moreover create a new label if you wanted to regularly switch between variegated configurations: LABEL ol6.2 KERNEL /ol6.2/vmlinuz APPEND initrd=/ol6.2/initrd.img ks=http://10.0.2.2/ks-vm.cfg For virtual machines I use a slightly variegated configuration compared to previously. I’ve only shown the changes below, not the full file: $ sudo cp /usr/share/nginx/www/ks.cfg /usr/share/nginx/www/ks-vm.cfg # Update network configuration for DHCP instead of static network --bootproto=dhcp url --url=http://10.0.2.2/ol6.2 # Don't specify disks, just use default layout bootloader --location=mbr --driveorder=sda clearpart --all --initlabel # Just add 'screen' to the default set of @base and @core packages. %packages screen %end Start Virtual Machine All that’s left to do is to marching up the VM, and everything else should run automatically. $ VirtualBox --startvm "${VM}" All done!
