HP ProLiant Essentials Server Migration Pack: New P2V tools from HP.  Features:

  • Systems Insight Manager Integration - enables all operations required for P2V or V2V migrations to be accessed from the SIM console
  • Automated P2V - automates the migration of physical servers into VMware ESX/GSX or Microsoft virtual machines
  • Automated V2V - automates the conversion of Virtual Machines between VMware ESX & GSX and Microsoft Virtual Server virtualization layers
  • Peer to Peer Migrations - accelerates the migration process and enables the ability to perform multiple P2V migrations concurrently
  • No boot CD required"

IBM offers VMware apps: "Hoping to inspire more enthusiasm among corporate and smaller users alike for virtualization technology, VMware signed a deal to bundle evaluation copies of its entire virtual infrastructure software line with all IBM Intel-based eServer BladeCenter servers.

VMWare Workstation raw disk with WinXP guest: Nifty trick of converting a dual-boot machine into a multi-OS VMware system.  Starts with dual boot Linux and XP; adds vmware under linux; creates an XP vm that runs off the XP partition in raw mode.  Result is much faster execution of XP, and continued ability to boot XP.  The downside is loss of snapshots and other virtual disk functions (obviously).  I wonder if VMware workstation 5 can create an unlinked clone of the XP partition, to convert it to a true virtual disk.  VMware today probably doesn't support cloning of raw disks, but if it did, it might make a more elegant p2v process -- boot, say, from a USB drive that has vmware, define a VM with a raw disk link to a partition, and clone it.  (See also VMware 4.5 docs, caveat, and support comment. Thanks to 'perigrin' in deli.cio.us)  9:39:19 AM  permalink

New Virtual Platform: "Chris Stone, late vice-chairman of Novell responsible for its acquisition of SUSE and Ximian, has surfaced on the shiny new advisory board of Virtual Iron Software Inc.. [Virtual Iron] claims it can virtualize anything from a fraction of a processor to large-scale multiprocessors. .. The company was founded in 2003 under the name Katana Technology Inc by chief scientist Alex Vasilevsky, a grid pioneer and Thinking Machines veteran, along with CTO and head of business development Scott Davis, the former CTO of Mangosoft who in his youth was technical director of DEC's VAXCluster, VMS Volume Shadowing and DEC's NT clustering technology."  Virtual Iron has raised $20m, has many luminaries on its advisory board. 

The product calims to combine multiple servers into a single fabric.  "Virtual Iron is betting that Linux will be the big growth driver in data center computing going forward and that many small servers will be racked up in these places like so many books in a library. VMware has spread its bet across the Windows and Linux worlds and believes that, increasingly, data center operators will use fewer machines with more processors in each. Either way, thanks to their advances, get ready to see microprocessors from Intel and AMD make tons of headway in the heavy-duty corporate computing scene. .. Virtual Iron's product, VFe (get it?), allows computing system managers to turn a host of Linux servers into a single virtual server, in real time shifting jobs from one server to another as computing demands dictate. The idea is that the system is much easier to manage this way, since all of the servers run on a single Linux operating system--rather than requiring each computer to run its own operating system. (Linux sellers Red Hat and Novell must be saying "Ouch!") Also, with a setup like this, there's less unused computing power sitting around idle."  Commercial availability of VFe release 1.0 will be in Q2 of 2005.  Initial support for x86 and SUSE and RedHat only.

Analyst opinions: "Pund-IT analyst Charles King said Xen is likely to be a greater threat to VMware than Virtual Iron, which he said sports an approach so different from VMware's that Virtual Iron will more likely compete with grid computing vendors like Platform Computing or United Devices.  .. IDC analyst Dan Kusnetzky said .. "On the edges, VMware and Virtual Iron will compete with each other. But VMware can't do what Virtual Iron does, which is spread resources among number of blades or boxes connected by InfiniBand. This is not to say VMware could not implement this, but it would probably take two to three years to implement."   [Thanks for the lead, Scott!]

Fedora Project Wiki - FedoraXenQuickstart: How to run Xen in Fedora.  "As some people have noticed, Xen is now available from the Fedora development repository. More information on Xen itself can be found at http://www.cl.cam.ac.uk/Research/SRG/netos/xen/index.html. We're following the -unstable Xen tree at the moment which does occasionally lead to things being broken but also lets us track a lot of the more interesting work going on there. Since setting up to run Xen isn't entirely straight-forward, here's a run-through of what should work for setting up a single Xen guest running the Fedora development tree."  9:26:04 AM  permalink

Solaris Zones Feature: Good intro to "Solaris Containers technology, a way to virtualize system resources and use multiple software partitions with one instance of the OS."   Built into Solaris 10.  I wonder if it runs on Intel x86 hardware; and if so, if it would run in a Solaris vm  under vmware.  I don't have an application in mind, just curious.  8:48:38 AM  permalink

Vizioncore: Backup and Control for VMWare ESX: Vizioncore provides products for ESX management that grew out of a consulting company.  For example, "esxRanger CLI runs on a windows host and can be scheduled to perform online hot backups of guest operating systems on VMware ESX Server. [It] compresses the disks before sending them to the destination server [with] NO Agents needed on the ESX Servers or the guest operating systems. .. esxRanger CLI uses the standard COM interface provided by VMware for adding and committing REDO logs. While it is possible to achieve a similar functionality with scripting, there are many hidden costs and known bugs to consider."  60-day eval available, starts at $125/server. "  A hardware appliance for swappable hard disk backup is under development.

John Howard - Virtual Server, Virtual PC: John Howard, IT Pro Evangelist, Microsoft UK, keeps a blog on many interesting topic, especially MS virtual computing products.  Recent samples:  how to share a vm desktop with VMRC with 2 or more simultaneous remote sessions; and how to use WMIC (Windows Management Interface Commands) to generate html pages with Windows system info.  9:04:11 PM  permalink  

Sysprepping a virtual machine: Details on use of the Windows Server sysprep command when cloning virtual machines.  3:54:35 PM  permalink  

Howto for UML: Steps for installation and use of the mature User Mode Linux platform. For new development, see FAUmachine: "We are working on an Open Source Virtual Machine which started out as a User Mode Linux, and which we therefore used to call UMLinux. Since the project has evolved from a User Mode Linux to a Virtual Machine we have chosen to give it the more appropriate name FAUmachine... FAUmachine development is supported by the European Community."  3:49:57 PM  permalink  

Linux-VServer: "the vserver project: It allows you to run linux inside linux: Any distributions inside any distributions. Each virtual server has its own packages, its own services, its own users and is confined to using some IP numbers only and some area(s) of the file system. You can think of them as virtual machines."  All vms are linux, and they share the host kernel.   So there is essentially no CPU overhead.  VM disks can be resized, and vms moved easily, just like other vm solutions, getting many vm advantages with almost no overhead costs.  Active development.  3:48:14 PM  permalink
