# Setup Ledger Nano S in Linux 
# according to http://support.ledgerwallet.com/knowledge_base/topics/ledger-wallet-is-not-recognized-on-linux
# However, in Fedora, the "plugdev" group is not existed (obsolete).
# The solution is to replace `GROUP=\"plugdev\"` to `OWNER=\"<username>\"` in the script, for example:
# Original rule: SUBSYSTEMS=="usb", ATTRS{idVendor}=="2c97", ATTRS{idProduct}=="0001", MODE="0660", GROUP="plugdev"
# Change to: SUBSYSTEMS=="usb", ATTRS{idVendor}=="2c97", ATTRS{idProduct}=="0001", MODE="0660", OWNER="ptantiku"

Disable cloud-init from CirrOS

Problem: when cirros boot, it takes too long to reach the login prompt, because it starts process of cloud-init.

1. Download cirros from CirrOS 0.3.5
2. convert .img file (qcow2 format) to .vdi or .vmdk format, using command:

   qemu-image convert -f qcow2 -O vmdk cirros_0.3.5_i386.img cirros_0.3.5_i386.vmdk

3. Create a new vm in virtualbox/vmware with the .vdi/.vmdk as its harddisk.

Create Boot CD for Openstack

Why?

I got stuck when trying to extend the root partition. The partition table ended up broken and I cannot boot into the system.

Preparation

• download Hiren Boot CD, it will come in .iso format
• install syslinux in the system (sudo yum install -y syslinux)

Make the CD image with partition table
