# HG changeset patch

# Node ID 899532500ada24763c01ad27f781701d8240be3a
# Parent 5ea87acc07dc748ad7aaa60e32bfd2f3a1fccfea
Add a parallel set of APIs to the domain builders to allow images and
ramdisks to be passed via buffer, rather than via file. This allows
usage of the underlying domain building routines in "file-challenged"
enviroments.
Specifically, xc_linux_build_mem is the buffer oriented version of the
file-oriented xc_linux_build. Likewise, xc_hvm_build_mem is the
buffer oriented analog of the file based xc_hvm_build.
