VMware ESXi Secure boot support for Dell EMC
PowerEdge Servers
VMware supports UEFI Secure boot on versions ESXi 6.5 or later. UEFI Secure boot in general verifies the integrity of every
package loaded as part of the operating system (OS) bootup. Secure boot verifies the integrity of the vSphere Installation
Bundle (VIB) packages loaded from the boot device.
ESXi Secure boot workflow
The mboot boot loader in ESXi contains a VMware public key and is validated against the Certificate Authority (CA) present
in the platform BIOS UEFI Secure boot authorized Database (DB) during ESXi boot. The boot loader uses this key to verify the
signature of the kernel and a small subset of systems that includes a Secure boot VIB verifiera VIB package that is used for
validating the signature of the drivers and other VIB packages loaded from the boot device. If any of the VIB installed on ESXi
does not match with the signature of the public key contained in the bootloader, then ESXi boot ends up with the Purple Screen
Of Death (PSOD) mentioning a signature mismatch for the specific failing VIBs.
