Over the last few days have I experimented with UEFI and GPT in VirtualBox 4.3.26. The goal was to multiboot various operating system, in this case Windows 10 Enterprise Technical Preview 9926 x64 and FreeBSD/amd64 stable/10. First, I thought of persuading the UEFI firmware to always present its boot menu. It sure beats remembering to […]

VirtualBox 4.3.24 is out, so I wanted to try out the UEFI version of the latest FreeBSD/amd64 stable/10 snapshot. It didn’t go well until I realised something important, however strange it may be.

Configuring X11 is more or less a dark art, and you must almost be a wizard of the Slytherine House to get modern X.org 1.14.7 working on a FreeBSD guest in VirtualBox. Nonetheless, through lots of experimentation this evening, have I finally arrived at this configuration file: Somehow, you need both the InputClass and the […]

Update 2014-11-30 Upgrading to Oracle VirtualBox 4.3.20 removed the timeout messages shown below. The bug was acknowledged in the change log as Storage: fixed an interrupt acknowledge issue causing hanging guests or slower I/O (4.3.18 regression) Since upgrading Oracle VirtualBox from 4.3.16 to 4.3.18 on my Windows 7 x64 host, most of my FreeBSD guests […]

Strangely enough, Java Runtime Environment (JRE) fails to register javaws.exe as the handler for .jnlp files when installed in Windows 8/8.1. Just remember to choose javaws.exe, not java.exe nor javaw.exe. Further more, Blackboard Collaborate insists on using 64-bit JRE on 64-bit Windows, i.e. visit the directories and files usually found in C:\Program Files\Java, not the ones […]

I have a bunch of FreeBSD VMs running in VirtualBox. They all share a number of virtual harddrives, and among them are a virtual harddrive with the common contents of /var/db/ports. My ports configuration of emulators/virtualbox-ose-additions have the OPENGL and X11 options set. This is useless on some of my simpler VMs, as those VMs […]

If you’re like me, eager to test new stuff in FreeBSD, you might as well run a virtualized FreeBSD laboratory on your desktop. I use Oracle VirtualBox, but you might as well use Microsoft Hyper-V, real hardware, or some other contraption. Couple this with ZFS and boot environments, and you’re even able to rapidly revert […]

Update 2015-01-05: I was more or less forced to adopt VT, UTF-8, KMS, and DRM2 when I upgraded my laptop from stable/9 to stable/10 in the time between Christmas of 2014 and New Year of 2015. My laptop, a Dell Latitude D531 of mid-2007 design, is equipped with the AMD/ATI Radeon X1270 GPU. What an […]

The latest Oracle Java RE 7u51 at its normal level of “High” security causes the Dell iDRAC6 virtual console (version 1.95 (Build 05)) to die with this Java trace: java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: https://hostname.some.domain:443/software/avctKVM.jar at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source) at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source) at com.sun.javaws.Launcher.doLaunchApp(Unknown Source) at com.sun.javaws.Launcher.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Simply […]
