is There any swap file for the ESXI host ?

Hi,

Yes it has, is a swap file that creates automatically during the installation and is for the VMkernel processes. See below the explanation from the "The Architecture of ESXi" book:

User Worlds:

The term “user world” refers to a process running in the

VMkernel operating system. The environment in which a user

world runs is limited compared to what would be found in a

general-purpose POSIX-compliant operating system such as

Linux. For example:

• The set of available signals is limited.

• The system API is a subset of POSIX.

•The /proc file system is very limited.

• A single swap file is available for all user world processes. If

a local disk exists, the swap file is created automatically in a

small VFAT partition. Otherwise, the user is free to set up a

swap file on one of the attached VMFS datastores.

In short, a user world is not intended as a general-purpose

mechanism to run arbitrary applications but provides only

enough of a framework for processes that need to run in the

hypervisor environment.

Several important process run in user worlds. These can be

thought of as native VMkernel applications and are described in

the following sections.
