The Xen project itself doesn't have anything to build disk images; just as KVM itself doesn't have anything to build disk images. It leaves that to higher-level tools. I know some people use virsh to install the guest, and then use the xl command-line to manage it after that; but I haven't tested that. It would be good to have recommendations on the wiki for a simple, standardized way to create guests in CentOS. >> If you describe which bit of documentation on the Xen website you >> tried to follow, what you were trying to do, and what happened, then >> we can figure out which of those it is and address the issue. > > Well, I didn`t really care about the documentation that didn`t work. > Like I said, using xl didn`t work because it only says the kernel can`t > be booted; xm seems to be deprecated (yet still used with centos), and > virsh-install works. *I* care about the documentation that didn't work, so that other people don't trip over the same thing. :-) If you've walked this path and become frustrated, there are probably a dozen other people who have also walked it and just not said anything.
