VM on ESX suspending

on
Environ:  ESXi 6.0 running in a single host.  Three VMs.  One is Server 2016 and the other two are Win10 LTSB for a total of three VMs.

One of the VMs keeps suspending.  It's one of the two Win10 LTSB VMs.  The server one is fine.

Resources on the host are not constrained.

Power mgt on both host and VMs is set to max performance.

I can't find where this one VM is suspending and how to fix it.

Places I can look?  Ideas?  Suggestions?

Thanks

Look in the main Windows 10 power management screen. Set to balanced or like. Make sure it has not been set for Airplane Mode

You think it's in the VM?  I thought about that, but it's spun up from a template.  I'll check it all the same.

It is a Windows 10 VM and Windows 10 has Control Panel Windows Power Management which you checked and the main power plans Window.  So yes, check this to ensure proper settings.

Just check in the Balanced Plan the Suspend Settings (default Balanced will suspend the machine).

There are only two places

Windows Power Management (A control panel-like Window)  and the Power Plans as we have discussed. Check all the settings and compare both machines

Make a third one from the template, no changes and see what it does.

A VM which is suspending on ESXi is caused by the Power Management in the OS.

Common issue in ESXi with Windows 7, 8 and 10.

Disable All Power Management [SLEEP and HIBERNATION] it's of no use in a virtual environment.
