Today we are going over a script I wrote to utilize the ovmcli to rename all virtual disks to follow a understandable standard, in this case we will take the vmname and append a disk identifier to it.  The first disk (slot 0) will be appended with “_system.img” with all subsequent being appended with “_dataX.img” […]

When using a Core version of Hyper-V 2008 R2, be it Hyper-V Server 2008 R2 or Windows Server 2008 R2 Standard Core, you are doing a good thing to conserve resources and minimize the attack footprint of your virtualization hosts. However this comes at a price. One of the most obvious misses in this matter is the enabling of Jumbo Frames on the Virtual Switch Interface.
