A Purple Screen of
Death (PSOD) is a diagnostic screen with white type on a purple background that
is displayed when the VMkernel of
an ESX/ESXi host
experiences a critical error, becomes inoperative and terminates any virtual machines that are running.
Typically, the PSOD
details the memory state at the time of the crash and includes other
information such as the ESX/ESXI version and build, the exception type,
register dump, what was running on each CPU at
the time of the crash, backtrace, server uptime,
error messages and core dumpinformation.
The core dump (or
memory dump) is a file that contains further diagnostic information from a PSOD
that can be given to VMware support to determine a root cause analysis for the
failure.
The term Purple Screen
of Death is a play on the Blue Screen of
Death, the informal name given by users to the Windows general
protection fault (GPF)
error.
