The VMware Tools label on the Summary tab changes to OK.
IMPORTANT When you upgrade VMware Tools on Linux guest operating systems, new network modules
are available but are not used until you either restart the guest operating system or stop networking, unload
and reload the VMware networking kernel modules, and restart networking. This behavior means that even
if VMware Tools is set to automatically upgrade, you must restart or reload network modules to make new
features available.
This strategy avoids network interruptions and allows you to install VMware Tools over SSH.
What to do next
Upgrade the virtual machine compatibility.
Upgrade the Compatibility for Virtual Machines
The virtual machine compatibility determines the virtual hardware available to the virtual machine, which
corresponds to the physical hardware available on the host machine. You can upgrade the compatibility
level to make a virtual machine compatible with the latest version of ESXi running on the host.
This procedure upgrades one or more virtual machines to the latest supported virtual hardware version
immediately. To schedule an upgrade for the next virtual machine reboot, and choose from all supported
virtual hardware upgrade versions, see “Schedule a Compatibility Upgrade for Virtual Machines,” on
page 247.
For information about virtual machine hardware versions and compatibility, see “Virtual Machine
Compatibility,” on page 89.
Prerequisites
n
Create a backup or snapshot of the virtual machines. See “Using Snapshots To Manage Virtual
Machines,” on page 192.
n
Upgrade VMware Tools. On Microsoft Windows virtual machines, if you upgrade the compatibility
before you upgrade VMware Tools, the virtual machine might automatically lose its network settings.
n
Verify that all virtual machines and their .vmdk files are stored on storage connected to the ESXi host or
the host cluster.
n
Verify that the compatibility settings for the virtual machines are not the latest supported version.
n
Determine the ESXi versions that you want the virtual machines to be compatible with. See “Virtual
Machine Compatibility,” on page 89.
