Virtualization - the bad stuff.

This is important stuff, especially if your new to it like I am, and don't have the budget for iSCSI, SAN or whatever else is out there.

Have a backup of the data on the VM.
Raid is not a VM Data backup.

Have a backup of the VM.
Raid is not a VM VHD backup.

Have a backup of the Host machine.
Raid is not a backup of a Server.

Have notes on all the machines, including at least the following and anything else you care and if you have extra please email them to me at -

IP's of all the machines both virtual and Physical.

Server names, FQDN and Netbios.

An odd one, but how long the physical machine needs to reboot, trust me, if your sitting there waiting for a machine to reboot and you thing that it should do it in 2 minutes, the 5 minutes it may take to reboot is real long and lonely.

Physical drive sizes, nice to know what should have been there.

Virtual drive sizes, again nice to know what should be there.

A set of Server XXX or whatever is your flavour disks, nothing like trying to rebuild a server when all you have is a XP Service Pack CD.

As a friend of mine calls it, a lifeboat machine. You need another box to run your VM's on if your main box crashes, I mean after all, isn't this part of the reason we are here...

Notes on the complete build, what did and did not go right. What programs are installed on each VM. This is real important if you have to rebuild a VM that did something...but what was it... Belarc will give you a nice report of all installed software.

All of this stored somewhere else other than on a VM or the Host machine. A printout is good, a CD is good, but whatever works for you.

A VM toolkit. start looking at some of the VM or VHD tools out there and see what can or cannot help you if a VHD disk gets corrupted.

Belarc - nice report on a server, hardware software etc.

VM Back - Driver Disk to open a VHD

WinImage - a program to allow you take a look at the data on a VHD

Hope this is of some use.

Norfolk Airport.

Just so I remember next time.
The VB Resort Hotel is about 20/ 25 minutes from the Airport.
The Marriot where we stayed in 2007 was about 45 minutes.

Thanks to Dave for the lift.

I have to leave.....I've had a great time, but between un-notified flight changes etc I had to leave early and I'm sad about that. I'm missing the end of JamesNT's talk on SQL, the finial words from Eric and Mark and the roundtable.

I was a bit aprehensive about the meeting as I wasn't sure that I'd have an interest in all of the stuff, but just the sheer energy comming from the speakers about their subjects is enough to infect their interest in you. I've had the hardest time trying to get my head around power shell and why I need it. But Don Jones, great speaker, made a point thats hard to not accept. If you want to be a 'high level IT' person in the windows world, you will have to be a Power Shell user. And PS2 is on its way. Everything in the Windows world will aparently be controlled from this interface.

For all its scareyness there appears to only be a few things in it. 16 Verbs as per some places, but 14 in others and approx 130 Nouns. Help actually works, and its almost close to readable language. At least I'm a bit more confident that I'll learn this thing.

I need to finish this up, but I think a plane is waiting.
