OVMF Debug Log Driver Slated For Linux 6.17 To Help Analyze UEFI VM Boot Issues
For those making use of Open Virtual Machine Firmware (OVMF) such as for UEFI booting of VMs with KVM+QEMU, the upcoming Linux 6.17 kernel is set to offer a convenient new driver to help in debugging the system boot when needed.
For those making use of Open Virtual Machine Firmware (OVMF) such as for UEFI booting of VMs with KVM+QEMU, the upcoming Linux 6.17 kernel is set to offer a convenient new driver to help in debugging the system boot when needed. Open Virtual Machine Firmware (OVMF) since edk2-stable202508 supports writing their debug log to a memory buffer. Coming with Linux 6.17 in turn is the "ovmf-debug-log" driver that when enabled via the new OVMF_DEBUG_LOG Kconfig switch will allow exposing that debug log memory buffer to system administrators via the Linux sysfs interface.
