Introducing VBareMetal!

I’ve been very busy lately, here is one of my latest incarnations, a Virtualisation Linux Distribution, which you can use as a live-cd or a bare-metal installer, it is debian based with virtualbox. Everything configured out of the box. You can run Linux/BSD/Solaris/Windows/Other virtual machines on this distribution, even if your system does not support virtualisation natively! =) Please note, this release is super early, it works, but very bare. In the coming weeks i’ll make it a pretty fully functional system. Continue reading

Hey guys :) this weekend I’ll try to write some cool how-to’s and things, But I’m running out of ideas heh, leave a comment on this post to let me know what you would like to see most, also if you could, could you all place a small link to my blog from your websites/blogs please :) this code will do it:

Thanks everyone, and don’t forget to comment =)

Recently i had a thought… Most of my machines are sitting redundant and have upto 4 drives in each… without unscrewing every single one of out of my rack… i want to utilise all of that space into one giant zpool using ZFS.

Imagine combining the drive space resources of 10 computers into 1 giant drive? see where i’m going with this now?

So my idea is to make the drives in each machine available to the “ZFS Master” (the solaris box running the ZFS pool) via iSCSI which is a sort of “offer your drives at a block level over ethernet” protocol… then add them all into a giant zpool… the advantages of this are:

  • Utilising all of my hardware
  • iSCSI can work over WAN so i could use boxes i have in other cities
  • Have each Lun “individual computer + drives” power up via WOL (wake on lan) initiated by the ZFS Master
  • Greater level of redundancy possible.
  • Backup “ZFS Master” possible
  • Everything connected via either Gigabit Ethernet or Fibre Channel.

So imagine.. a rack full of computers with hard drives in them… at the bottom is a more powerful computer running solaris which mounts the hdd’s of every single other computer and adds them into the zpool… then advertises this zpool over AFP / SMB to computers in my house…

Yet another way to make a α size tb system out of old free components that could possibly outperform a £20,000 solution! =) I’ll post all of the results of my testing after the break in a few days :)

P.S. This idea is without considering performance as that is something i can work out later :) & thanks bda for your advice

Hurricane Electric, the most reliable tunnel broker in my opinion have always provided ipv4 exhaustion statistics as found somewhere on this site! however, they’ve now launched an iPhone application and gadgets/widgets for google desktop and windows. From the email they sent me i quote:

“We have just released a free iPhone App, Webpage Widget, and
Google and Windows Desktop Gadgets that report the growth of IPv6 deployment and the exhaustion of IPv4.”

I thought it would be worth  mentioning as i know lots of readers here have iPhones :) . The iPhone App, Webpage Widget, and Desktop Gadgets are available at:

So you’ve probably wondered why i went from posting 3 times a day to not posting at all. I’ve been pretty busy recently with exams, jobs, personal-issues and so on. Few bits of news regarding the project. I’ve moved house, therefor am going to migrate everything thats using UKERNA over to HE.NET purely as they seem to be much more stable, and I can use 6over4 :) Also i am working on something you are all gonna like, just gimme time and i’ll have it sorted :) need to buy a more powerful server first heh :)

For now peace! and stay tuned for whats coming next :)

ETA: 2 weeks

As you all know, i’m a big fan of virtualisation, however when i purchased my Sony Vaio VGN-FW31E the thing that highly disappointed me was that the VT-x extensions were disabled for the CPU, and there was no option in the BIOS to enable them, however i knew the CPU inside this laptop did indeed support VT-x.

For those of you who are wondering WTF? am i on about, VT-x extensions in the CPU allow virtualisation software such as Sun Virtualbox, Vmware, Linux KVM and others to perform direct real virtualisation rather than passing everything through the host os. This really improves speed / performance on virtual machines, aswell as allowing 64bit guests on a 32bit OS (as long as the host CPU is 64bit capable). It is really a must.

Anyway… After being annoyed for a long time i came across this website, on it the clever guy Igor has basically made a utility which grabs your bios from EEPROM, backs it up, patches it (by changing 1 bit only!) and reflash’s it back to your VAIO. Once this is done, VT-x extensions are enabled!!! however there are a few important notes / qwerkyness things. Anyway check out Igor’s site for full instructions, information and download!

If any of you have been recently experiencing connectivity issues with the site or problems with zones generated using the zone builder, these bugs have been now rectified.

The zone builder was not specifying a $TTL correctly, Also as all of my zones are generated here, my bind9 stopped working properly. All fixed now, sorry for any inconvenience caused :)
