VirtualBox 5.0 Released July 9!

Posted by essjae on July 14, 2015

VirtualBox 5.0 (released 2015-07-09)

This is a major update. The following major new features were added:

  • Paravirtualization support for Windows and Linux guests to improve time-keeping accuracy and performance (see the manual for more information)
  • Make more instruction set extensions available to the guest when running with hardware-assisted virtualization and nested paging. Among others this includes: SSE 4.1, SSE4.2, AVX, AVX-2, AES-NI, POPCNT, RDRAND and RDSEED
  • xHCI Controller to support USB 3 devices (see the manual for more information)
  • Drag and drop support (bidirectional) for Windows, Linux and Solaris guests
  • Disk image encryption (see the manual for more information)
  • VMs can now be started in separate mode. The VM process is started headless while the frontend runs as a separate process which can be terminated without stopping the VM.
  • GUI: VM guest-content scaling support (including 3D acceleration)
  • GUI: New User Interface settings page for customizing status-bar, menu-bar and guest-content scaling
  • GUI: New Encryption settings tab for customizing encryption options for disk images
  • GUI: HiDPI support including application icons and optional unscaled HiDPI output on Mac OS X (including 3D acceleration)
  • GUI: Hot-plugging support for SATA disks
  • New, modular audio architecture for providing a better abstraction of the host audio backends
  • Support for the NDIS6 networking framework on Windows (default on Vista and later)

Exciting “new” Linux distros: SolydXK and Kwheezy

Posted by essjae on September 27, 2013

I stumbled across these two relatively new distros in my search for a Windows replacement.

Kwheezy is a great distro, almost everything you need is pre-installed and it’s got some great eye-candy.  http://www.kwheezy.com/en/.  Here’s a good review of Kwheezy: http://mylinuxexplore.blogspot.com/2013/08/kwheezy-11-review-good-debian-spin-for.html

SolydXK isn’t quite the “everything but the kitchen sink” distro, but it’s also a really good option.  http://www.solydxk.com

Both are based on Debian’s stable branch.  Kwheezy 1.2 is based on Debian 7.1.

I’m really leaning toward one of these two for a full install on my secondary machine…potentially replacing the Windows 7 install, but definitely a dual boot install.

Parallels Workstation/Workstation Extreme products cancelled for Windows and Linux

Posted by essjae on April 9, 2013

I went over to Parallels tonight to search for some info and found that their website only mentions the Mac product.

I dug a little deeper in the support forums and found this sad little post:

Parallels Workstation – End of Purchase or Renewal Ability Notification

We are ending sales of our Parallels Workstation product lines in order to focus on some different market segments and products. Effective immediately, you will no longer be able to purchase new licenses or renew maintenance on the following products:

·         Parallels Workstation

·         Parallels Workstation Extreme

What does it mean for you?
* Parallels will no longer release patches or updates for these products;

* Parallels Support will not be able to escalate the requests to the development team for patches/fixes which are not covered in existing version/build of the product.

* If you have a personal Support Plan, please contact your Parallels sales representative or one of the Parallels offices.

I wanted Parallels and the Workstation product to succeed, but you can only ignore a product and customers for so long.

Disabling a Dell PointStick (TrackStick) in CrunchBang Linux

Posted by essjae on April 9, 2012

I recently discovered CrunchBang Linux, an awesome Debian based distro, and have been testing it as an alternative to Windows 8.

I installed it on a spare Dell D630 notebook at work and found out the the little pointstick caused the pointer to randomly wander around the screen.  Since I never use the PointStick I wanted to disable it.  In Windows, there is a nice little Dell utility that allows you to customize the behavior of the PointStick and TouchPad.

However, in Linux, it’s a little different (command line), but almost as easy.

The key tool is xinput (thanks to this post on ceder’s blog)

You can disable the device via a couple simple commands:

"xinput list"
# xinput list
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ Microsoft Microsoft Wireless Optical Mouse® 1.0A    id=10    [slave  pointer  (2)]
⎜   ↳ DualPoint Stick                             id=12    [slave  pointer  (2)]
⎜   ↳ AlpsPS/2 ALPS DualPoint TouchPad            id=13    [slave  pointer  (2)]
⎜   ↳ Macintosh mouse button emulation            id=14    [slave  pointer  (2)]
⎣ Virtual core keyboard                       id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]
    ↳ Video Bus                                   id=6    [slave  keyboard (3)]
    ↳ Video Bus                                   id=7    [slave  keyboard (3)]
    ↳ Power Button                                id=8    [slave  keyboard (3)]
    ↳ Sleep Button                                id=9    [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard                id=11    [slave  keyboard (3)]

to find the “DualPoint Stick” device

# xinput -set-prop "DualPoint Stick" "Device Enabled" 0
to disable it

Linux Integration Services 3.2 released for Hyper-V

Posted by essjae on December 2, 2011

New version of the IC was released yesterday (1-Dec-2011).

http://www.microsoft.com/download/en/details.aspx?id=28188

Overview

When installed in a supported Linux virtual machine running on Hyper-V, the Linux Integration Components provide.

Driver support: Linux Integration Services supports the network controller and the IDE and SCSI storage controllers that were developed specifically for Hyper-V.

Fastpath Boot Support for Hyper-V: Boot devices now take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.

Timesync: The clock inside the virtual machine will remain synchronized with the clock on the virtualization server with the help of the pluggable time source device.

Integrated Shutdown: Virtual machines running Linux can be shut down from either Hyper-V Manager or System Center Virtual Machine Manager by using the “Shut Down” command.

Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.

Heartbeat: Allows the virtualization server to detect whether the virtual machine is running and responsive.

KVP (Key Value Pair) Exchange: Information about the running Linux virtual machine can be obtained by using the Key Value Pair exchange functionality on the Windows Server 2008 virtualization server.

Integrated Mouse Support: The cursor is no longer bound to the VMConnect window when used with the Linux Graphical User Interface.

====

New/updated from 3.1 release:

  • Synthetic Mouse Support: The virtualized mouse device is no longer bound to the VMConnect window, and can now be used with a RDP session.
  • Merged Device Drivers: We now present a single device driver for both IDE and SCSI devices (hv_storvsc).
  • Windows 8 Fix: The synthetic network device (hv_netvsc) can now be used with a Windows 8 host, eliminating the hang on boot that was previously seen.
  • SCVMM Fix: This release fixes the issue as described in KB2586286.
  • Improved Setup Experience: Users now only need to run install.sh (as root) to automatically detect the correct architecture and install the appropriate drivers.

Posted by essjae on May 17, 2011

http://blogs.technet.com/b/openness/archive/2011/05/15/expanding-interoperability-to-community-linux.aspx

“Specifically, effective immediately, Microsoft will support Windows Server2008 R2 Hyper-V to run CentOS. CentOS is a popular Linux distribution for Hosters, and this was the number one requirement for interoperability that we heard from that community. “

Installing VirtualBox 3.2 in Debian-based Linux Mint 9

Posted by essjae on October 13, 2010

I have struggled with this in the past, since VBox requires some different versions of packages that aren’t easily accessible/installable…at least until I found this hint.

  1. Download VBox
  2. From a terminal
      sudo dpkg -i "vbox-version".deb
      sudo apt-get -f install

That's it
