Computerhok 2013#
Intro#
The old computerhok is running for almost 5 years now (Ubuntu 8.04, both hypervisor and guests), time for something new.Functions to be ported from old to new#
- Gallery
- JSPWiki, including apache frontend
- home for geocaching hof images
- nagios (on a separate guest or on hypervisor?)
- fail2ban like solution (see current ~/bin/cron/blockHost.sh)
- backuphost for krm2DB
- a backup hardware node on remote location, and easy backup
- dhfds
- http://www.esthercreations.nl
can retire
- webmin still necessary ?
- mail server (not open relay!, see /etc/postfix/main.cf)
- uptime script
- OpenVZ logo should go from homepage
VirtualBox#
We will no longer use OpenVZ, it is too restrictive in choice of guest OS'es.
We intend to use VirtualBox as hypervisor, and Ubuntu 12.04 LTS as both host and guest OS.
Work in progress / install log#

VirtualBox installation#
- install packages
- add deb http://download.virtualbox.org/virtualbox/debian precise contrib
- add the apt key : sudo apt-key add oracle_vbox.asc
- apt-get install virtualbox-4.2
- create test VM:
root@apollo:~# VBoxManage createvm --name Ubuntu1 --ostype Linux --register Virtual machine 'Ubuntu1' is created and registered. UUID: 1ed5e417-1eca-4a60-b6d4-5c8f40e44019 Settings file: '/root/VirtualBox VMs/Ubuntu1/Ubuntu1.vbox' root@apollo:~#
- modify attributes (more memory, VT off, network bridged instead of NAT:
VBoxManage modifyvm Ubuntu1 --memory=512 --hwvirtex=off --hwvirtexexcl=off --vtxvpid=off --boot1=dvd --boot2=disk --boot3=none --nic1=bridged --bridgeadapter1=wlan0 --nicpromisc1=allow-all --vrde=on --vrdeport=13389
- Add CD and disk:
VBoxManage storagectl Ubuntu1 --name='IDE Controller' --add=ide --controller=PIIX4 --bootable=on VBoxManage storagectl Ubuntu1 --name='SATA Controller' --add=sata --controller=IntelAhci --bootable=on
- show me how you look now:

- attach the CD image
VBoxManage storageattach Ubuntu1 --storagectl='IDE Controller' --port=1 --device=1 --type=dvddrive --medium=/tmp/ff/ubuntu-12.04.1-server-i386.iso
- create HD:
VBoxManage createhd --filename '/root/VirtualBox VMs/Ubuntu1/disk1.vdi' --size=15000
- attach HD:
VBoxManage storageattach Ubuntu1 --storagectl='SATA Controller' --port=1 --device=0 --type=hdd --medium='/root/VirtualBox VMs/Ubuntu1/disk1.vdi'
- fire up the VM :
VBoxManage startvm Ubuntu1 --type=headless
Deleted the kernel source again to free up some disk space:
