			<content:encoded><![CDATA[<p>It is possible to backup a Hyper-V server without taking it down using the Hyper-V VSS writer.</p>
<p>The way I do it is with a small batch file that is run as a scheduled task. The command is quite simple.</p>
<blockquote><p>WBADMIN START BACKUP -backupTarget:&#8221;\\<span style="color: #ff0000;">SERVER\BACKUP_SHARE</span>&#8221; -user:<span style="color: #ff0000;">DOMAIN\USERNAME</span> -password:<span style="color: #ff0000;">PASSWORD</span> -include:C:,D: -vssFull -quiet &gt; c:\Backup\hyperbackup.log</p></blockquote>
<p>As you can see the command is output to a text file located at c:\Backup\hyperbackup.log so that you can check the progress.</p>
<p>As I will always forget to check on it I set another scheduled task to run a VBS file to e-mail the log to me.</p>
<p>This is the vbscript I use.</p>

			<content:encoded><![CDATA[<p>Here is my process for installing Hyper-V on a Windows 2008 Server.</p>
<p><strong>Basic install</strong></p>
<p>First make sure the hardware can support virtualisation. <a  href="http://www.grc.com/securable.htm" target="_self">Securable</a> is the easiest tool for this.</p>
<p style="text-align: center;"><a  href="http://gravo.co.uk/wordpress/wp-content/uploads/2010/02/AllFeatures.png" class="thickbox no_icon" rel="gallery-157" title="AllFeatures"><img class="size-thumbnail wp-image-158 aligncenter" title="AllFeatures" src="http://gravo.co.uk/wordpress/wp-content/uploads/2010/02/AllFeatures-150x150.png" alt="" width="150" height="150" /></a></p>
<p>If Securable shows a failure check these setting (names may vary) in the BIOS</p>
<ul>
<li>Security &gt; Execute Disable (set to On)</li>
<li>Performance &gt; Virtualization (set to On)</li>
<li>Performance &gt; VT for Direct I/O Access (set to On)</li>
<li>Performance &gt; Trusted Execution (set to Off)</li>
</ul>
<p>Next install Server 2008 Enterprise as normal</p>
<p>Once the install has finished install all drivers, run windows update and add to the domain (or not).</p>
<p>Run Add Roles from server manager and select Hyper-V.</p>
<p>On the virtual networks page select the adapter(s) you want to use to give physical network access.</p>
<p>Complete the installation process and reboot the server. Log back in with the same account you started the install with and let it finish the install proccess.</p>
<p>You can now create / manage the virtual network / machines from server manager or from the Hyper-V mmc snap-in.</p>
<p><strong>Additional Steps</strong></p>
<p>I use the<a  href="http://mindre.net/post/Hyper-V-Monitor-Gadget-for-Windows-Sidebar.aspx" target="_self"> Hyper-V Monitor gadget</a> to monitor my virtual servers. This gadget relies on pinging the server as part of the monitoring process. By default ICMP is blocked by the windows firewall. The easiest way of enabling ICMP is from the command prompt with the line</p>
<blockquote><p>netsh firewall set icmpsetting 8</p></blockquote>
<p>And your done!</p>

Simply choose the software you want and run the installer. Your favorite apps installed silently and with any junk automatically removed (i.e. Toolbars and adware).

I don&#8217;t normally trust these things but this one is really good.

The parts list is pretty simple -

2m of 25&#215;25x3mm Angle Iron
2m of 25&#215;15x3mm Angle Iron
5m of 3mm steel rod
300&#215;300mm steel plate

			<content:encoded><![CDATA[<p>I&#8217;ve gotten bored of trying to balance bits of old disposable BBQ on rocks when camping so I decided to make a folding grill.</p>
<p>The parts list is pretty simple -</p>
<ul>
<li>2m of 25&#215;25x3mm Angle Iron</li>
<li>2m of 25&#215;15x3mm Angle Iron</li>
<li>5m of 3mm steel rod</li>
<li>300&#215;300mm steel plate</li>
<li>4 x nuts and bolts</li>
</ul>
<p>This is also a good excuse for me to buy some new tools like a welder!</p>
<p>I did try to scrounge the parts for this but the scrap men have done a pretty thorough job of taking anything not bolted down so I had to buy most of it new.</p>
<p>Step 1</p>
<p>Cut 45 degree  mitre&#8217;s in the Angle Iron</p>
<p><a  href="http://gravo.co.uk/wordpress/wp-content/uploads/2009/05/plan.jpg" class="thickbox no_icon" rel="gallery-56" title="plan"><img class="aligncenter size-medium wp-image-61" title="plan" src="http://projects.gravo.co.uk/wp-content/uploads/plan-300x18.jpg" alt="plan" width="300" height="18" /></a></p>
<p>Step 2</p>
<p>Heat the bend points and slowly bend the metal.</p>
<p>Step 3</p>
<p>Weld the two corners of the Angle Iron together and weld the steel plate at one end. As you can tell by the picture this is the first time I have ever welded! I would have made the welder myself from microwave transformers but when you can buy them from eBay for £20 it&#8217;s not really worth it.</p>
<p><a  href="http://gravo.co.uk/wordpress/wp-content/uploads/2009/05/nasty-welding1.jpg" class="thickbox no_icon" rel="gallery-56" title="nasty-welding"><img class="alignnone size-thumbnail wp-image-59" title="nasty-welding" src="http://projects.gravo.co.uk/wp-content/uploads/nasty-welding1-150x150.jpg" alt="nasty-welding" width="150" height="150" /></a><a  href="http://gravo.co.uk/wordpress/wp-content/uploads/2009/05/welder.jpg" class="thickbox no_icon" rel="gallery-56" title="welder"><img class="alignnone size-thumbnail wp-image-63" title="welder" src="http://projects.gravo.co.uk/wp-content/uploads/welder-150x150.jpg" alt="welder" width="150" height="150" /></a></p>
<p>Step 4</p>
<p>Cut the rods to length and weld them on.</p>
<p>Step 5</p>
<p>Grind down all of the nastyness and spray on some high tempreture BBQ paint.</p>
<p><a  href="http://gravo.co.uk/wordpress/wp-content/uploads/2009/05/painted.jpg" class="thickbox no_icon" rel="gallery-56" title="painted"><img class="aligncenter size-medium wp-image-60" title="painted" src="http://projects.gravo.co.uk/wp-content/uploads/painted-225x300.jpg" alt="painted" width="225" height="300" /></a></p>
<p>Step 6</p>
<p>Cut the legs to length and cut a notch in to one end so that they can hinge then drill the legs and frame and bolt it all together. I also added some cross bracing to the legs to stableize the whole thing.</p>

As you can see in the following pictures it is simply powered by a 12volt cordless drill battery and even comes with it&#8217;s own carry case.</p>
