Im not sure if this is of use to anyone here but you never know.
Microsoft has recently released Service Pack 1 for 2008 R2.
There are some niffty upgraded/new features for Hyper-V Virtulisation servers regarding memory utils etc.
At work we run three Hyper-V Host Servers containing around 35 VM Guest Servers.
We upgraded our Host servers last week and started to notice slow downs on the network which got worse as time went by.
Today we spent the wole day backing up all of our servers and uninstalling Service Pack 1 on the three main servers.
After the initial upgrade the network traffic between our servers and iScsi SAN was horrendously slow. One of our servers took 1.3 hrs to boot. We also lost 2 LUNS (and servers) on our SAN which had been working perfectly before the upgrade.
Neadless to say its been a very stressfull week but we are back to normal again after removing SP1.
Just wanted to warn others if you are thinking of upgrading. I would hold off for the moment as I found that on the Microsoft Forums one of their senior technical guys admitted there was a bug and a fix was coming sometime after the 18th April.
Alot of other people were in the same boat as us, I found out after some google digging.
Well the good news is that my Chrome front indicator bulbs, side light smd's and rear number plater 501's were wating for me when I got home tonight.
At least I get to play tomorrow morning with the Vec again. A much more enjoyable experience that servers/computers.
