To install packages, first configure it to use our local package proxy by typing vi /etc/apt/apt.conf and putting in this one line: Acquire::http::Proxy '' Jeos is a very minimal install, it doesn't even have an openssh server. 3.1 Login to the VMĬonnect to your VM's VNC console - by now you should know how to do this, or ask for help.Īt the console, login as root/root, and type ifconfig to find out what IP address your VM has picked up via DHCP. This will take over the given logical volume and rename it to the Ganeti standard (UUID-based), without running any OS installation and since we didn't specify -no-start it will also start it running. The -n flag gives the node where you created the logical volume. You will create an instance and tell Ganeti to adopt the logical volume you have created. The final parameter is where you want to write the output.The next parameter is the input you are reading.-O raw says the format you want the output to be written in (just a raw stream of blocks).Now unpack the VMDK and write it to this volume: # qemu-img convert -O raw /iso/ub1404lts-disk1.vmdk /dev/ganeti/jeosX Lrwxrwxrwx 1 root root 7 May 15 09:32 /dev/ganeti/jeosX ->. Also check that a new block device has been created under /dev/ganeti # ls -l /dev/ganeti/jeosX Type lvs to see that your logical volume is present. This ensures all the logical volume names are unique) (replacing X with your group number, e.g. Now create a logical volume of exactly that size. Let's just check this is exactly 1GiB, using a calculator program bc: # bc (Note that this is using Gibibytes, where 1GiB = 1024^3 bytes)

What you need to know is the size of the disk drive which is being emulated, and you can find this out using qemu-img info # qemu-img info /iso/ub1404lts-disk1.vmdk That doesn't tell us much, because a VMDK file is an image which grows as it is used. Have a look at the file you're going to use: # ls -l /iso/ub1404lts-disk1.vmdk For example, if you are working with host2 then login to host2, not the cluster master node. 2 Importing a VMDKĭo this part of this exercise on whichever host you want the virtual machine to be created on. This will work efficiently because there will be no fragmentation on the host it can also be converted easily to DRBD if you wish. Since Ganeti won't work directly with vmdk files, you are going to convert it into a logical volume. You are going to import a tiny Ubuntu 14.04 installation called 'Jeos' from the vmdk software appliance provided.
