Today I was following up on some harmless messages I have been seeing on some iSCSI Initiators I have setup that provide disk to a number of ESX servers over a Gigabit LAN. It appears that there may be some limitations running the newest flavour of ESX with current IET. One recent comment from [...]  It seems that Virtualbox 3.1.x now implements a quick check to see if the hardware virtualization extensions are in use before launching AMD-V enabled guests. There seem to be two key issues with this change Buggy BIOS’s that do not clear a VERR_SVM_IN_USE flag properly on boot KVM modules that set the VERR_SVM_IN_USE flag [...] Recently somebody asked me about key verification and signing after noting that emails from some sources (in this case, the Debian Security team) contain key signatures for verification, and that by default the Evolution email client was not validating them. The simple answer is that by default Seahorse, the default key manager for Ubuntu [...] Lately I have been getting a hard lockup on a work laptop, and I suspect it may be temperature related. Unfortunately with the latest Karmic kernel (2.6.31-17-generic x86_64) I am seeing the following message on boot: [ 0.943491] ACPI Exception: AE_OK, No or invalid critical threshold 20090521 thermal-384 Additionally, there is no output reported [...] Recently I acquired a Novatel Ovation MC950D UMTS Modem. A quick google to find links on how to setup revealed a few generic methods, with nothing very Ubuntu specific. As is turns out, the Mobile Broadband setup is build right into the Network Manager. I simply configured a udev script to activate the [...] After mucking about with various combinations of grub2, xen and eucalyptus on Ubuntu Karmic and eventually Debian Squeeze I now have a working cloud computing sandbox using binaries entirely from debian packages. The final configuration is a Debian Squeeze instance on my HP dv7z laptop running standard grub2, xen and eucalyptus packages. The kernel [...] For some time now I have observed the Ubuntu dmesg line [ 10.799981] input: ST LIS3LV02DL Accelerometer as /devices/platform/lis3lv02d/input/input8 and wondered if this was (a) a properly recognized piece of hardware, (b) a feature of my laptop or my Seagate STxxxxxxxx hard disk and (c) what applications might take advantage of it, assuming I [...] The holidays are all about relaxing; For me, this means a bit of time exploring new technologies during my 18mo son William’s afternoon nap, typically from 1-3pm each day. Today, I am looking at getting a package-based eucalyptus cloud running on my ZM-80-based laptop, as an experiment for future updates to my linux infrastructure. [...] Responding to a LinkedIn discussion asking on how to clean up the boot menu and remove old or obsolete kernel packages, I have posted this quick set of steps I used today and from time to time to execute this task. With the GUI, there are a lot of options, with the most [...] Things are looking great for Jaunty, and the already released Debian Lenny. For virtual hosting, nothing is like the Debian v5.0 rock – stable and fully supporting Xen. For standalone web servers, Ubuntu Jaunty is very similar, and just a bit newer. With WordPress 2.7 and Gallery 2.3 + WPG2 supported out of the [...] |
