[PATCH 1/2] Add no-virt mode to livemedia-creator

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Brian C. Lane" <bcl@xxxxxxxxxx>

This runs anaconda directly, using the --image install feature. The host
system should be the same release as the target system in order to avoid
unexpected problems.
