At Work with Linux: RHEL 6 and VirtualBox 3.2.12

Virtual Machines 2011
A Dell 690 with RHEL 6 as the host OS.
Virtual Box 3.2.12 is running Fedora 14
 in a virtual machine.
It's been a little over two months since I last wrote about using Virtual Box with Redhat Enterprise Linux (RHEL). At that time I was attempting to host a Fedora 14 virtual machine on RHEL 5.4. This time, I upgraded one of the RHEL 5.4 boxes to RHEL 6, and installed Virtual Box 3.2.12 (and before you write to me in the comments, I'm well aware that VB 4 has been released).

What you're looking at on the left is a Fedora 14 VM running under Virtual Box 3.2.12 r68302. The host OS is RHEL 6 x86-64.

Absolutely everything works, especially USB device sharing between the host and the VM. Under RHEL 5.4, USB device sharing refused to work. I suspect that the older kernel that RHEL 5 was based on would not support that capability. RHEL 6's more up-to-date kernel allows that particular feature to function, and function flawlessly (so far).

To date I've installed and tested RHEL 6 Server, RHEL 5.6 Server, and Fedora 14 as Virtual Box VMs hosted on RHEL 6 Server. I can't tell from my limited testing if performance is better or worse, but I can't tell the difference between older versions of Virtual Box on older versions of RHEL and this current setup. Regardless, everything runs smooth as butter.

One other feature that moving up to RHEL 6 brings, and that's the ability to install (via RPM) and run Chrome, specifically version 8. Not only is everything in place on RHEL 6 to support error-free installation, but Chrome 8 on RHEL 6 updates itself just like it does under Windows. I no longer have to depend upon Redhat (or Fedora, for that matter) to release security updates; it comes directly from The Google. Now, if only Firefox 4, when it's released, will do the same.

No other issues to talk about. As a server and development platform (primarily Java EE, Mule ESB, and JBoss) it provides a trouble free platform. For a desktop, I'd rather stick with Windows, installed on hardware or as another VM.

The right tool for the right job.

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…

vm networking problem fixed

Over the weekend I upgraded to Windows 8.1, then discovered that networking for the virtual machines wouldn't work. Then I tried something incredibly simple and fixed the problem.

Checking the system I noticed that three VMware Windows services weren't running; VMnetDHCP, VMUSBArbService, and VMwareNatService. VMware Player allows you to install, remove, or fix an existing installation. I chose to try fixing the installation, and that fixed the problem. The services were re-installed/restarted, and the virtual machines had networking again.

Once network connectivity was established there was exactly one updated file for Ubuntu 13.10, a data file. This underscores how solid and finished the release was this time. Every other version of every other Linux installation I've ever dealt with has always been succeeded by boatloads of updates after the initial installation. But not this time.

Everything is working properly on my notebook. All's right with the world.

sony's pivotal mirrorless move

I'm a died-in-the-wool technologist, even when it comes to photography. I have always been fascinated with the technology that goes into manufacturing any camera, from the lenses (optics) through the mechanical construction, the electronics involved, and especially the chemistry of the film and the sophistication of the digital sensor. It's amazing that the camera can do all it's asked of it, regardless of manufacturer.

Of all the types of cameras that I've really taken an interest in, contemporary mirrorless (again, regardless of manufacturer) are the most interesting because of the challenging problems the scientists and engineers have had to solve in order to build a compact but highly functional camera. In particular I've followed the sensor advances over the years and watched image quality climb (especially with μ4:3rds) to exceed film and rival one another such that there's very little difference any more as you move from the smaller sensors such as 4:3r…
