We have a HyperV 2008 cluster and every so often the VMs will go missing from the network. You go to the console and it says you can not use your mouse, and the screen is small, you can not resize it and it has no bars to move up and down, so all you can see is the top left hand side of the screen.
We can recue it by migrating it from one machine to the other and its then fine but we would like to stop it happening in the first place. Any one seen this before?
