No patches, no place on the virtual net

摘要

One critical but often overlooked management task in a virtual environment is how to raise a computer securely from suspend, or sleep, mode. The issue is making sure the machines that have been in a sleep state are opdated and patched before allowing them to go live on the virtual network. This is handled differently depending on the virtualization management provider. As part of its life-cycle program, for example, Novell keeps varying states of virtual servers in a controlled "warehouse."
