I recently had the need to get a USB to 1-Wire bus adapter working on an Ubuntu Virtual Machine running inside a Ubuntu host. Both systems were Ubuntu Server 10.04. However, after testing under Windows, where the USB device worked perfectly, when exported to the Ubuntu host, the USB device was always ‘busy’. Here are my findings on how to resolve this issue to a successful conclusion. Continue reading HowTo: Enabling a USB device in a VirtualBox VM in Ubuntu » OWFS, the One Wire Filing System for Linux is a very useful interface for communicating with the Maxim 1-Wire range of devices. Most of the commentaries on how to install OWFS refer to much older versions of Ubuntu than 10.04, this article is an upgraded version to cover the newer versions of the packages concerned.

With the Oracle VirtualBox, this is no exception. Time keeping on some of my VMs has been a serious issue. I tried to used NTP to resolve the problem, however the clock accuracy is so poor within the VM, that the offsets and jitters are far too large for the clock correction algorithms to correct. So an alternative solution was needed. It appears this was a well documented problem. The resolution was to make sure that I was using a version where this issue had been fixed in the Guest Additions.

The main problem I haves that the main cURL site was down at the time (for me anyway). Now that you have the basic controls of your Virtual Machine (VM) in place, we can move on to slightly more useful tasks. This third article in the series, we will discuss more topics to get your system further down the line. If you missed the previous instalments , you can catch up here: Continue reading Series: Ubuntu VirtualBox Host III – Control » |
