Tech Virtualization Xenserver Howtos Automated install of Kali Linux VM (64 bit) using preseed

Automated install of Kali Linux VM (64 bit) using preseed

Note: This has not really been tested yet. I wanted to get it up here so people can start using it and I can work on it.

Install Type

  • Non-interactive
  • Network boot
  • Commandline
  • Paravirtualized

Prerequisites

  • XCP/Xenserver
  • Access to Internet
  • Working DHCP server
  • Working DNS name resolution
 

Introduction

In this tutorial I create a disk, download a kernel, preseed file and install Kali LInux using the preseed file. This has proven very popular since you can't install a paravirtualized domain using an install disk. This has been a very nice installation howto because you don't have to download any install CD/DVDs and you could create VMs using nothing more than a commandline login. It's also very nice because it can be mirrored locally if you're doing a bunch of them just by rsyncing a Ubuntu mirror locally then downloading my files and editing them.

 

 Note: This tutorial is designed so you can copy and paste the text inside the boxes. I don't actually type any of this in and neither should you.

 

1. Getting the network info

This line gets the Network UUID for xenbr0. If you're using a different bridge you will want to insert it here. Get a list of XCP networks with xe network-list. This network is connected to the outside interface. This tutorial requires there to be a DHCP server on this network answering requests and providing network access to the Internet.

NETUUID=$(xe network-list bridge=xenbr0 --minimal)

 

2. Creating the VM and setting parameters

Here we create a new template from the Debian Squeeze template. Then we create the VM from the new Debian template, create a network interface and add it to our network from step one. Additional settings are for configuring the install repository and specifying thepreseed file from my site. The last setting turns off VNC so we can watch the install via a text console (very important in my environment).  Even if you can't see all the text below just highlight and paste. The text is there even if it's not visible.

 

TMPLUUID=$(xe template-list | grep -B1 'name-label.*Debian.*Squeeze.*64-bit' | awk -F: '/uuid/{print $2}'| tr -d " ")
VMUUID=$(xe vm-install new-name-label="Kali Linux" template=${TMPLUUID}) 
xe vif-create vm-uuid=${VMUUID} network-uuid=${NETUUID} mac=random device=0
xe vm-param-set uuid=${VMUUID} other-config-install-repository=http://http.kali.org
xe vm-param-set uuid=${VMUUID} other-config:debian-release=kali
xe vm-param-set uuid=${VMUUID} other-config:install-methods=http,cdrom,ftp,nfs
xe vm-param-set uuid=${VMUUID} PV-args="netcfg/get_hostname=Kali debian-installer/locale=en_US console-keymaps-at/keymap=us console-setup/layoutcode=us console-setup/ask_detect=false interface=eth0 netcfg/disable_dhcp=false preseed/url=http://grantmcwilliams.com/files/preseed-kali-linux.cfg console=hvc0"
xe vm-param-set uuid=${VMUUID} other-config:disable_pv_vnc=1

 

3. Starting the VM and watching the install

The VM installs without any interaction from the user at this point. It is however, nice to watch it using xenconsole. Once it's done installing it will shutdown.

If you're using XCP 1.0/1.1

xe vm-start uuid=$VMUUID
DOMID=$(xe vm-list uuid=${VMUUID} params=dom-id --minimal)
/usr/lib/xen/bin/xenconsole ${DOMID

If you're using XCP 1.5b/1.6

xe vm-start uuid=$VMUUID ; xe console uuid=$VMUUID

4. Starting the VM and configuring settings

We need to boot the VM up again and using xenconsole log in to reset the finish configuration.

If you're using XCP 1.0/1.1

xe vm-start uuid=$VMUUID
DOMID=$(xe vm-list uuid=${VMUUID} params=dom-id --minimal)
/usr/lib/xen/bin/xenconsole ${DOMID}

 

If you're using XCP 1.5b/1.6

xe vm-start uuid=$VMUUID
xe console uuid=$VMUUID

 

Now that your Kali Linux VM is running you can login. The password was automatically set by the preseed file.

  • Username: root
  • Password: password

Reset the root users password.  If you want to keep the IP assignment dynamic note the ip address.

5. Shutting down the VM and re-enabling VNC

If you're going to use XVP or some other method of connecting to the VMs direct VNC connection you'll need to enable it.

xe vm-shutdown uuid=$VMUUID
xe vm-param-remove uuid=${VMUUID} other-config:disable_pv_vnc
xe vm-start uuid=$VMUUID

 

7. Export our VM for safe keeping

Before you start modifying the base Kali Linux image you should back it up.

xe vm-export uuid=$VMUUID filename=Kali-Linux-base.xva

 

 

Be aware that you may not have enough space on the Control Domain's disk to export it. A good solution (and shorter than explaining how to add disks to the control domain) is to mount an nfs volume and export it there.

mount nfsserver:/share /media/share
xe vm-export uuid=$VMUUID filename=/media/share/Kali-Linux-base.xva

 

This would mount the NFS share on nfsserver to /media/share. The exported disk would be saved on the NFS share.
