It’s one thing to set up a new workload. It’s another thing entirely to keep it running. All production workloads require at least a bit of attention. Maybe resources configured for a virtual machine (VM) at installation have fallen behind an application’s requirements as its usage expands and it gets upgrades. Perhaps a driver update installed on the host caused issues with storage. Maybe every VM on the host started running slowly for no apparent reason. These are examples of issues you might encounter while maintaining a virtualization environment. This chapter helps you predict, identify, locate, and resolve problems in your Hyper-V deployment.
