Secure boot can be enabled: All vib signatures verified. All tardisks validated. All acceptance levels validated
Hardware machine is configured to boot in legacy BIOS mode.
Booting stops early in the boot process with messages displayed in red on black with wording similar to “Error 10 (Out of resources) while loading module”, “Requested malloc size failed”, or “No free memory”.
“Error 10 (Out of resources) while loading module”, “Requested malloc size failed”, or “No free memory”
VMware’s recommended workaround is to transition the machine to UEFI boot mode permanently, as discussed in KB article 84233 . There will not be a future ESXi change to allow legacy BIOS to work on this machine again.
VMware’s plans to deprecate support for legacy BIOS in server platforms.
If you upgrade a server that was certified and running successfully with legacy BIOS to a newer release of ESXi, it is possible the server will no longer function with that release. For example, some servers may fail to boot with an “Out of resources” message because the newer ESXi release is too large to boot in legacy BIOS mode. Generally, VMware will not provide any fix or workaround for such issues besides either switching the server to UEFI
Motivation
UEFI provides several advantages over legacy BIOS and aligns with VMware goals for being “secure by default”. UEFI
UEFI Secure Boot, a security standard that helps ensure that the server boots using only software that is trusted by the server manufacturer.
Automatic update of the system boot order during ESXi installation.
Securing Cloud Applications demystifies complex security protocols, algorithms, and patterns, and demonstrates how to put them into practice in everyday development.
The deployment wizard for VMware Cloud Builder (CB) can accept either an XLSX or JSON configuration file that describes your desired VMware Cloud Foundation (VCF) deployment. Interestingly enough, only an XLSX template is available for users to download, edit and then provide that back as user […]
After installing Windows Server 2022 update KB5022842 (OS Build 20348.1547), guest OS can not boot up when virtual machine(s) configured with secure boot enabled running on vSphere ESXi 6.7 U2/U3 or vSphere ESXi 7.0.x.
In VM vmware.log, there is ‘Image DENIED’ info like the below:
2023-02-15T05:34:31.379Z In(05) vcpu-0 - SECUREBOOT: Signature: 0 in db, 0 in dbx, 1 unrecognized, 0 unsupported alg.
2023-02-15T05:34:31.379Z In(05) vcpu-0 - Hash: 0 in db, 0 in dbx.
2023-02-15T05:34:31.379Z In(05) vcpu-0 - SECUREBOOT: Image DENIED.
To identify the location of vmware.log files:
Establish an SSH session to your host. For ESXi hosts
Log in to the ESXi Host CLI using root account.
To list the locations of the configuration files for the virtual machines registered on the host, run the below command:
#vim-cmd vmsvc/getallvms | grep -i "VM_Name"
The vmware.log file is located in virtual machine folder along with the vmx file.
Record the location of the .vmx configuration file for the virtual machine you are troubleshooting. For example:
Currently there is no resolution for virtual machines running on vSphere ESXi 6.7 U2/U3 and vSphere ESXi 7.0.x. However the issue doesn’t exist with virtual machines running on vSphere ESXi 8.0.x.
