A quick note about extracting and recreating RHEL6 or Centos6 (and their derivations) installation media components:
mv initrd.img /tmp/initrd.img.xz
xz –format=lzma initrd.img.xz –decompress
cpio -ivdum < ../initrd.img
Xen has long history and many features. Sometimes even experienced developers cannot be sure whether their new code is regression-free. To make sure new code doesn’t cause regression, Ian Jackson developed a test framework called OSSTest. In order to make this framework usable for individual ad-hoc testing, standalone mode was introduced. Recently I played with it and found it useful to share my experience with the community.
The Xen Project was well represented at LinuxCon North America and CloudOpen North America. Sponsored by the Linux Foundation, the two co-located conferences featured a number of Xen-related talks, as well as the first Xen Project User Summit (which will be discussed at length in a post to follow).

The goal – connecting multiple Oracle ASM snapshots (same source LUNs, of course) to the same machine. The next process will demonstrate how to do it.
