These are my notes on how to configure some aspects of VMWare ESXi when operating it on a standalone server with the free license.
ESXi's SSH server must first be enabled via the host client (web interface).
Actually, on ESXi, it is a Purple Screen of Death (PSOD)
This command checks whether the system is configured to automatically reboot after a purple-screen failure:
esxcfg-advcfg -g /Misc/BlueScreenTimeout
It tells you the number of seconds it will wait after a crash before rebooting. 0 means no reboot.
To change the value to, for example, 120 seconds:
esxcfg-advcfg -s 120 /Misc/BlueScreenTimeout
