How can I boot from an LVM snapshot on Red Hat Enterprise Linux?

Solution Unverified - Updated -

Issue

  • Test changes to your Operating System without impacting the installed OS until the changes have been verified to work.
  • Is there a way to boot a LVM root snapshot? I can restore a root snapshot and boot it, but I want to boot the snapshot without restoring first.

Environment

  • Red Hat Enterprise Linux (RHEL), including:
    • Red Hat Enterprise Linux 5 (RHEL5); or
    • Red Hat Enterprise Linux 6 (RHEL6)
  • Root volume is an LVM2 device
