Installing Xen Cloud Platform (XCP) from USB
Last week we started a new series of articles that will provide you with all the information you need to create your own private cloud and virtual desktop infrastructure. In the first article we covered Getting Started with Xen Cloud Platform (XCP). Today, we are going to show you how to create your own Xen Cloud Platform USB Installer and walk through the installation process.
For this installation I will be installing to an ITX Server that I recently built. If you want to check out the build log hit us up on the forums.
Meet the Xen Cloud Platform XCP Hosts
- Case: iStar S-21
- Motherboard: Intel S1200KPR
- CPU: Intel Xeon E3-1265L
- Ram: Crucial 16GB Kit (2x8GB) 240-Pin DIMM DDR3 PC3-12800 CT2KIT102472BA160B
- HDD: Intel 320 Series 40GB SSD
- VM Storage: Hosted on a NFS Share from my Synology DS1812+
Software you need
Creating the Xen Cloud Platform XCP USB Installer
The USB drive does not need to be very large but it does need to have a FAT32 partition. The installer itself is only about 400MB. After you create your FAT32 Partition you are ready to image the drive with the XCP Installer.
- Start unetbootin
- Select Diskimage and then your XCP 1.6 ISO image that you downloaded
- Select USB Drive under Type
- Select your thumb drive device
- Press OK
After this completes we have a few steps to accomplish so that your thumbdrive will work properly:
- Open your thumbdrive
- Rename the file syslinux.cfg to syslinux.cfg.bak
- Rename the directory boot/isolinux to boot/syslinux
- Rename the file boot/isolinux/isolinux.cfg to boot/isolinux/syslinux.cfg
- Rename the file boot/isolinux/isolinux.bin to boot/isolinux/syslinux.bin
Not renaming the syslinux/isolinux files will get you an Unfound kernel error on boot.
Installing XCP from USB
Now just insert your USB drive into your host and boot to the USB device!
Today I will be installing this to one of my ITX Hosts that I built. After booting to your newly created USB XCP Installer you should be greeted with this screen. If you do not hit enter it will automatically boot into the installer.
After the boot process you will see a series of familiar Linux Distro Install Questions. I have not detailed each of them here because I am expecting you to be able to choose your own keyboard type, accept EULAs, warnings, etc. The important screens I have captured below.
Virtual Machine Storage – During the Installer you have to choose a default storage repository for VM Storage. Don’t worry we will be changing this later to our Shared Storage on the Synology DS1812+. I have not checked the Thin Provisioning option because we will not be storing VMs on this disk.
Next choose Local Media in the Xen Cloud Platform installer:
Now decide if you want to add any supplemental packs. As a note: No…you can always (easily) add stuff later.
Skip Installation Verification – This is usually a waste of time, just double check the checksum after you download if you are worried about it though.
Set a Password – Do not forget this, you will need it to manage your host.
Networking – I prefer to set Static IPs for my hosts because XenCenter (what we will use to manage the hosts) does not handle resources changing IPs very well. You will also set your hostname, DNS servers, Time Zone, and NTP Servers.
Finally Install XCP!
Now we just have to play the waiting game. This should not take very long, on the system listed above it took about 5 minutes.
When it completes, choose OK and remove your USB device.
After a reboot, you will be greeted with a cute little panda loading screen.
After bootup you will see the administrative console – Here you can modify all system settings as well as open the shell.
For the most part this will be unneeded as you will be doing most of the changes from the XenCenter Management tool.
Stay tuned for the next installment! We will be covering XenCenter and will show how to add a host, add a storage repository, modify host settings, and create your first Virtual Machine!
