VirtualBox - convert RAW image to VDI and otherwise

Posted in Linux, Backup, Recovery, VirtualBox, Virtualization
VirtualBox command-line interface (VBoxManage) provides an easy way to convert raw disk image to the VDI/VMDK format and otherwise.

Let's assume that we have raw image of the sdb device:

$ sudo dd if=/dev/sdb of=./sdb.raw
To use it with VirtualBox we need to convert it to the VDI format:

$ VBoxManage convertdd sdb.raw sdb.vdi --format VDI
To use it with VMware we need to convert it to the VMDK format:

$ VBoxManage convertdd sdb.raw sdb.vmdk --format VMDK
Convert between VDI/VMDK formats:

$ VBoxManage clonehd sdb.vdi sdb.vmdk --format VMDK
$ VBoxManage clonehd sdb.vmdk sdb.vdi --format VDI
Convert to the RAW image:

$ VBoxManage clonehd sdb.vdi sdb.raw --format RAW
Alternative solution to get back raw image after applying modifications is to use qemu-img command from qemu package:

$ qemu-img convert -f vmdk sdb.vmdk -O raw sdb.raw
Now we can write image to the device:

$ sudo dd if=./sdb.raw of=/dev/sdb

How to do Arithmetic Operations in Ansible

You can use arithmetic calculations in Ansible using the Jinja syntax. This is helpful in many situations where you have stored the output of an operation, and you need to manipulate that value. All usual operation like addition, subtraction, multiplication, division, and modulo are possible. Let us start with an example. We will be using the  debug module  to print the out the result. The following tasks show all the basic arithmetic operations. The output is given in comments. Ansible arithmetic operation example - hosts: loc tasks: - debug: msg: "addition{{ 4 +3 }}" #Ansible addition 7 - debug: msg: "substraction {{ 4 - 3 }}" #Ansible arithmetic substraction 1 - debug: msg: "multiplication {{ 4 * 3 }}" #multiplication 12 - debug: msg: "Modulo operation {{ 7 % 4}}" #ansible Modulo operation - find remainder 3 - debug: msg: "floating division {{ 4 / 3}}" #ansible floating divisio...

#install ipmitool (this is for debian) apt-get install ipmitool #insert the kernel modules needed for ipmi modprobe ipmi_devintf modprobe ipmi_si modprobe ipmi_msghandler #get the current mode (01 00 is dedicated mode) ipmitool raw 0x30 0x70 0x0c 0 #send the raw command to enable dedicated lan ipmitool raw 0x30 0x70 0xc 1 1 0
Ansible - Appending to lists and dictionaries  n this blog post I'll show how to add items to lists and dictionaries, when using loops, and across tasks. Normally when trying to add a new item to the variable, while in the loop, or between tasks, Ansible will ovewrite the values, keeping the result of the last iteration. For example, let's see what will be the result of running the following playbook: --- - name: Append to list hosts: localhost vars: cisco: - CiscoRouter01 - CiscoRouter02 - CiscoRouter03 - CiscoSwitch01 arista: - AristaSwitch01 - AristaSwitch02 - AristaSwitch03 tasks: - name: Add Cisco and Airsta devices to the list set_fact: devices: "{{ item }}" with_items: - "{{ cisco }}" - "{{ arista }}" - name: Debug list debug: var: devices verbosity: 0 [przemek@quasar blog]$ ansible-playbook append_list.yml PLAY [Append to list] ****************...
