Hyper-V Sidebar Gadget
Tore Lervik has made a great little Hyper-V Sidebar Gadget available on his website: http://mindre.net/post/Hyper-V-Monitor-Gadget-for-Windows-Sidebar.aspx
This gadget allows you to see the status of virtual machines on multiple servers "at a glance" and to quickly connect to them with the Virtual Machine Connection program.
I have this installed on my computer now - and find it very useful. So go check it out!
Cheers,
Ben
