| USB Boot: Undoable Stack Boot |
| ============================= |
| |
| Boot DevStack from a USB disk into a RAM disk. |
| |
| Prerequisites |
| ------------- |
| |
| Hardware |
| ~~~~~~~~ |
| |
| This guide covers the creation of a bootable USB drive. Your computer |
| BIOS must support booting from USB and You will want at least 3GB of |
| RAM. You also will need a USB drive of at least 2GB. |
| |
| Software |
| ~~~~~~~~ |
| |
| Ubuntu 11.10 (Oneiric Ocelot) is required on host to create images. |
| |
| Installation bit blasting |
| ------------------------- |
| |
| Set Up USB Drive |
| ~~~~~~~~~~~~~~~~ |
| |
| - Insert the USB drive into the computer. Make a note of the device |
| name, such as ``sdb``. Do not mount the device. |
| - Install the boot system: |
| |
| :: |
| |
| tools/build_usb_boot.sh /dev/sdb1 |
| |
| This calls tools/build\_ramdisk.sh to create a 2GB ramdisk containing |
| a complete development Oneiric OS plus the OpenStack code checkouts. |
| It then writes a syslinux boot sector to the specified device and |
| creates ``/syslinux``. |
| |
| - If desired, you may now mount the device: |
| |
| :: |
| |
| mount /dev/sdb1 /mnt/tmp |
| # foo |
| umount /mnt/tmp |
| |
| Now `return <ramdisk.html>`__ to the RAM disk Guide to kick off your |
| DevStack experience. |
