Hi Guys

For those of you out there running XenServer, and using Linux.. Look into XOA/Xen-Orchestra if you need an alternative to running XenCenter on Windows..

https://xen-orchestra.com/

The basic version is free, but if you want to play around will the full version without the support, there is an alternative:

Build XOA from the source, cause yes… XOA is open source…

Instruction are available here:

https://github.com/MrMEEE/xoa-community

I will try to provide RPMs in time..

Remember, I’m not responsible for the code or stability.. just trying to share 🙂

Hi guys

Red Hat recently released Ansible Tower to the community, under the name AWX..

But, the installation instructions only instructs us on howto spin up an installation inside docker instanses…

I have been working on howto do an “old fashion” installation… and here it is:

BEWARE: There might be dragons…

Please submit issues here:

And so I got Beta access to Blizzards newest game, Hearthstone.. And as always, I play it on Linux…

Installation:

Download installer from you Blizzard Battle.net account.

mkdir /home/username/Games/Heartstone/
WINEPREFIX=/home/username/Games/Heartstone/.wine winecfg

In winecfg, override “dbghelp”-> disabled and “msvcp100”-> Native under Libraries.

then run:
WINEPREFIX=/home/username/Games/Heartstone/.wine winetricks wininet

And then install:

WINEPREFIX=/home/username/Games/Heartstone/.wine wine Hearthstone-Beta-Setup-enGB.exe

click->click->click->click…

Game installed, and running beautifully.. Good job Blizzard.. Again.. next best thing to native Linux games, are Windows games that just runs..

And I must say, that Hearthstone is also a very nice game so far…

Today I struggled with migration of some Windows 2003 machines from VMWare to XenServer.

The guys that were migrating the machines were using Symantec to backup the VMWare machines and restore them to XenServer.

Apparently it seems like the way that Symantec configure the virtual machines, is no longer compatible with XenServer after the upgrade from 5.6 -> 6.0/6.1/6.2. When they migrated a Windows 2003 machine it started on XenServer with no issues, but when XenTools were installed, the machines stopped during bootup with Error code 0x0000DEAD (Kinda funny :D)..

By comparing the virtual machine configuration, I have developed this small script to fix the issue:

#!/bin/bash
xe vm-param-clear param-name=platform uuid=$1
params=”nx=false pae=true apic=true acpi=true stdvga=0 viridian=true”
for i in $params;do
xe vm-param-set platform:$i uuid=$1
done

The script should be fed with the UID of the virtual machine, accessiable through “xe vm-list”.

Hope this will someone out there..

And so, it’s time for a new project…

The last few years I been working a lot with a mix of SpaceWalk, Red Hat Network Satellite, SuSE Manager, ZenWorks, Puppet, Chef, CFEngine, Landscape and many other ways of managing and deploying Linux Servers..

I’m not saying that these tool are bad or not functioning.. but I always end up with problems/challenges that annoys me, and in the end makes me feel like the software could have been better.. For the bigger solutions in the Spacewalk Family (Satellite, Spacewalk, SuSE manager), I feel that software solutions like tomcat and Oracle are overkill for the purpose..

Recently a lot of people have been talking Cloud, and indicating that the future is mobile datacenters and no locale installation.. For my part, I don’t believe it .. I still think we’ll need locale installations in the future..

So now I have decided that I will try to it better myself…

I’m aiming for:

Cross-platform compability (First off, I will try to support RHEL,CentOS,Fedora,SLES,OpenSuSE,Debian and Ubuntu).. The software should also be installable on these platforms..

Full life Circle management (Deployment, Patch Management, Configuration, Monitoring)

Integration to Virtualization (VMware, XenServer, ProxMox)

Simple technologies for simple operations

The “Cloud” in “rainCloud”, should be the ONLY place this term is used.

Right now, most of the work is only in my head.. but I hope that a test version should be completed around Christmas.. (Hopefully sooner)..

I’m keeping the code open @github.. and if anyone should be interested in being a tester in the future, please contact me at mj@casalogic.dk or Twitter @martinjuhl

So.. I decided to try to promote Linux as a gaming platform…

I know it might not be as easy for some games as it could be, but I try..

Follow my gaming experiences here: http://www.twitch.tv/im60erWell.. så har jeg besluttet mig til at prøve at reklamere lidt for Linux til gamere…

Jeg ved godt at ikke alle spil er lige nemme at få til at køre.. men jeg prøver så godt jeg kan…

Følg mine hyggelige timer med at få diverse spil til at køre på Linux her: http://www.twitch.tv/im60er

So… just wanted to share with you guys, that I received my OUYA OpenSource Android Based Gaming Console…

I’m definitly going to post some reviews of games.. but for now, let me just say that i’m very impressed with the hardware quality…

Sure, there are still improvements to be made in the software.. but it actually works pretty great…

And one of the good things about OpenSource: If you don’t like it… Fix it… and Share it…

Hoping that I will have the time this summer to look into creating applications for the OUYA or even do some development on the interface.. I have some ideas, but right now I’m just enjoying the small box..

Also, I just want to mention that I have installed XBMC on the OUYA.. which works great together with my tvheadend backend, and streaming both 720p and 1080p.. The WIFI in the OUYA lacks a little speed on streaming 1080p movies, but Wired network works perfectly..

If you haven’t heard anything about the OUYA, or want to purchase on.. this is a good place to start: https://www.ouya.tv/

FireSSH is a Firefox plug-in that allows you to ssh from your Firefox Web Browser :)..

Sweet..
