Additional files are created when you perform certain tasks with the virtual machine.

A .hlog file is a log file that is used by vCenter Server to keep track of virtual machine files that must
be removed after a certain operation completes.

A .vmtx file is created when you convert a virtual machine to a template. The .vmtx file replaces the
virtual machine configuration file (.vmx file).
Virtual Machines and the Virtual Infrastructure
The infrastructure that supports virtual machines consists of at least two software layers, virtualization and
management. In vSphere, ESXi provides the virtualization capabilities that aggregate and present the
host hardware to virtual machines as a normalized set of resources. Virtual machines run on ESXi hosts
that vCenter Server manages.
vCenter Server can pool the resources of multiple hosts and lets you effectively monitor and manage your
data center infrastructure. You can manage resources for virtual machines, provision virtual machines,
schedule tasks, collect statistics logs, create templates, and more. vCenter Server also provides vSphere
vMotion™, vSphere Storage vMotion, vSphere Distributed Resource Scheduler (DRS), vSphere High
Availability (HA), and vSphere Fault Tolerance. These services enable efficient and automated resource
management and high availability for virtual machines.
The vSphere Client is the primary interface for managing vCenter Server, ESXi hosts, and virtual
machines. The vSphere Client also provides console access to virtual machines.
Note For information about running virtual machines on an isolated ESXi host, see the vSphere Single
Host Management documentation.
The vSphere Client presents the organizational hierarchy of managed objects in inventory views.
Inventories are the hierarchal structure used by vCenter Server or the host to organize managed objects.
This hierarchy includes the monitored objects in vCenter Server.
