Occasionally we will deploy a virtual instance into our KVM infrastructure and realize after the fact that we need more local disk space available. This is the process we use to expand the disk image. This process assumes the following:

• You're using legacy disk partitions. The process for LVM is similar and I will describe that in another post.

This process will work with either a qcow2 or raw disk image. For

Session state at disconnection

TCP and HTTP logs provide a session termination indicator in the
"termination_state" field, just before the number of active connections. It is
