Xen: How to Convert An Image-Based Guest To An LVM-Based Guest

Filed under
HowTos

This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it is often better to use LVM.

linuxjournal.com: Let's face it, databases are only minimally human-readable. In fact, to anybody who's not an accountant or a computer geek, reading databases can be downright intimidating. However, this limitation is partially compensated by the fact that reports in Base are quick and easy to create and are displayed and printed in Writer.

  • My Experiences Converting Users To GNU/Linux
    My wife, TLW, runs GNU/Linux with few problems. She uses a tablet, an Odroid-C2 ARMed thick client, and a big notebook all running Debian GNU/Linux or Ubuntu and her Android/Linux smartphone and her scanner and printer all deal with Beast, my GNU/Linux server. I have her file-system plugged in via NFS so she can do IT in bed, in front of the TV, on TV, or in her office and all her thousands of pictures, documents, scans etc. are all in the same place. She doesn’t even have much problem using Ubuntu or XFCE4 on Debian because she mostly uses the same applications all day long. It just works for her and memories of That Other Operating System are fading. She was locked to a single thick client with limited capabilities in those Dark Days. She had repeated crashes and malware. Today, her issues with IT are things like changing the name of a file on the FTP server or how to scan a light image or…, real problems, not problems M$ causes billions of people every day.
  • Shame on Microsoft for Leaving Surface Pro Customers in the Dark
    When Microsoft came out with its first batch of Surface tablets a few years ago, the company took a bath on them. It didn't help that they were conceived around the unpopular Windows 8 and the now-defunct Windows RT and that the prospects for the OS were in question. After Microsoft wrote off $900 million on its money-losing Surface business, the deathwatch was on. But the Intel-based Surface Pro and Surface Pro 2 showed a glimmer of hope, and Microsoft finally delivered a solid hit with the Surface Pro 3. After that water­shed release, the Surface division is now an important business that brings in more than $1 billion revenue per quarter. Yet Microsoft isn't showing much appreciation toward the customers who helped put its Surface business on solid footing.

  • ContractPatch, Step 2: Understanding the power balance
    At the point you are presented with a job offer, your prospective employer really wants to hire you. Chances are, they’ve screened and interviewed a number of candidates and put a lot of work into the process. Your manager has thought deeply about who they want in the position and has probably imagined how it will all work out with you in the role. Both you and the hiring decision-maker(s) are probably very optimistic about what you’ll accomplish in the role and how well you’ll get along working together. At this point, no one wants to go back to the drawing board and start the process over again. You will be excited to start the new job but it’s worth taking a step back to appreciate the unusual position you are in with your new employer.

  • Black Lab Linux 8 Beta 3 Is Out with Full EFI Support, Based on Ubuntu 16.04 LTS
    Softpedia was informed today, September 26, 2016, by Black Lab Software's CEO Robert J. Dohnert about the availability of the third Beta development snapshot of the upcoming Black Lab Linux 8 GNU/Linux operating system. Black Lab Linux 8 "Onyx" Beta 3 is here approximately three weeks after the second Beta pre-release and it comes with a major change. It is no longer based on Ubuntu 14.04 LTS (Trusty Tahr), as the development team decided to switch base and move to the next Ubuntu LTS version, namely Ubuntu 16.04 LTS (Xenial Xerus).
  • DevOps: All Development, No Database
    Since the last time I touched working code in a production environment, it’s no exaggeration to say that no part of the development process remains untouched. Over the last decade plus, effectively every aspect of the application development process has been scrutinized, rethought and in many cases reinvented. From version control to build systems to configuration and deployment to monitoring, modern development’s toolchain is multi-part and sophisticated. As it must be. Processes that work for code released in cycles measured in months cannot be expected to handle workflows measured in days or minutes. For all that the process of developing software has evolved, however, the database remains curiously overlooked. Consider the example of Cloud Native. Describing a modern, typically legacy-free approach to building applications appropriate for cloud environments, the term Cloud Native has gone from informal descriptor to accepted industry shorthand in short order – to the extent that it has its own technical foundation. If we look at the membership of that foundation, the CNCF, it would appear that the roster includes no database vendors at the Platinum or Gold membership levels, at least if you assume Google’s involvement is around Kubernetes and not tools such as BigQuery. Of the 41 silver members, meanwhile, two can be considered database vendors: Crunchy and Treasure Data.

  • What does it mean to change company culture?
    Tools are specific concrete things that a culture has decided is a way to improve a process. Buckminster Fuller has a great quote about tools and thinking: "If you want to teach people a new way of thinking, don't bother trying to teach them. Instead, give them a tool, the use of which will lead to new ways of thinking." In particular, DevOps tools can provide folks new ways to look at things—like delivering code into a production environment, for example. But there's lots of examples where a new tool doesn't influence the thinking of the people who use it, so things don't change.

Many people desire to be part of open source and contribute but often don’t know how they can, whether because they think they lack the skills or they just don’t have the time.

  • Public licenses and data: So what to do instead?
    Why you still need a (permissive) license Norms aren’t enough if the underlying legal system might allow an early contributor to later wield the law as a threat. That’s why the best practice in the data space is to use something like the Creative Commons public domain grant (CC-Zero) to set a clear, reliable, permissive baseline, and then use norms to add flexible requirements on top of that. This uses law to provide reliability and predictability, and then uses norms to address concerns about fairness, free-riding, and effectiveness. CC-Zero still isn’t perfect; most notably it has to try to be both a grant and a license to deal with different international rules around grants.
  • NIST Releases New 'Family' of Standardized Genomes
    With the addition of four new reference materials (RMs) to a growing collection of “measuring sticks” for gene sequencing, the National Institute of Standards and Technology (NIST) can now provide laboratories with even more capability to accurately “map” DNA for genetic testing, medical diagnoses and future customized drug therapies. The new tools feature sequenced genes from individuals in two genetically diverse groups, Asians and Ashkenazic Jews; a father-mother-child trio set from Ashkenazic Jews; and four microbes commonly used in research. NIST issued the world’s first genome reference material (NIST RM 8398)—detailing the genetic makeup for a woman with European ancestry—in May 2015. Together, all five RMs serve as a collection of well-characterized, whole genome standards that can tell a laboratory how well its DNA sequencing processes are working by measuring the performance of the equipment, chemistry and data analysis involved.

  • Pairing LLVM JIT With PostgreSQL Can Speed Up Database Performance
    Using the LLVM JIT with PostgreSQL can vastly speed up the query execution performance and shows off much potential but it hasn't been mainlined yet. Dmitry Melnik presented at this month's LLVM Cauldron over speeding up the query execution performance of PostgreSQL by using LLVM. Particularly with complex queries, the CPU becomes the bottleneck for PostgreSQL rather than the disk. LLVM JIT is used for just-in-time compilation of queries.
