5 Things I learned the hard way while setting up Hyper-V
1. Hyper-V can only be turned on in 64 bit versions of Windows Server 2008. Don’t spend 4 hours downloading and installing the 32 bit version DVD from MSDN, realise the Hyper-V role doesn’t exist, and then another 4 hours downloading and installing the 64 bit version.
2. Make sure you RTFM and enable the hardware virtualisation in your BIOS or it just won’t work.
3. Make sure you download all automatic updates as Windows Server 2008 shipped without Hyper-V. It has to be downloaded as an update. Remember to turn auto updates on too.
4. If you want more than 4 virtual machines, you need Windows Server 2008 Data Centre edition.
5. Dell Poweredge 5110 take ages to boot up, and the installation of Windows Server 2008 needs many restarts. Hyper-V itself takes an age itself to install. Get a good book as you are going to be doing lots of sitting around.
On the up side, Hyper-V is a fantastic technology and I have managed to re-purpose a high spec server into 5 high spec VPSs making us thrifty in these hard economic times, and greener and friendlier to the planet by opting for virtualisation.
Another year jars to a halt and without any pause for thought a new one appears.
