Sorry but I did not understand what you mean.

VMware doesn't provide a separate kernel, only VMware tools which
include Guest OS drivers.


Do I also need to install "linux-virtual" metapackage, which includes a
separate virtualisation kernel "linux-image-2.6.32-23-virtual"?:


Linux kernel image for version 2.6.32 on x86/x86_64

This package contains the Linux kernel image for version 2.6.32 on
x86/x86_64.

Also includes the corresponding System.map file, the modules built by
the
packager, and scripts that try to ensure that the system is not left in
an
unbootable state after an update.

Supports Virtual processors.

Geared toward virtual machine guests.

You likely do not want to install this package directly. Instead,
install
the linux-virtual meta-package, which will ensure that upgrades work
correctly, and that supporting packages are also installed.

Canonical provides critical updates for linux-image-2.6.32-23-virtual
until October 2011.




Thanks a lot.
