UEFI support for Windows update.

The KB5012170 security update for Windows Server 2019, Windows 2022 and Windows 10 has increased the boot system UEFI requirements. It requires a larger virtual memory (NVRAM) for the boot system because of the “Pre-Enrolled Keys”. This update provides a second UEFI image that meets the new requirements. If the Windows update is aborted with the error message 0x800f0922, the used UEFI image can be changed on the administration interface. When editing a VM, two options for UEFI are now available under “Boot system”. The previous one as “UEFI (legacy 2M Image)” with 2 MB NVRAM and the new “UEFI” with 4 MB NVRAM. The latter must be set so that the Windows update can be installed.

The monitoring system Nagios warns and alarms when RAID controller temperatures are too high. With this update the thresholds have been slightly increased, warning is now at 90° C instead of 85° C and alerting at 100° C instead of 95° C. Please note: Not all controllers have sensors for temperature.
