[Bug 1923497] [NEW] bios_linker_loader_add_checksum: Assertion `start_offset < file->blob->len' failed

[Ed Davison]

Public bug reported:

Trying boot/start a Windows 10 VM.  Worked until recently when this
error started showing up.

I have the following installed on Fedora 33:
qemu-kvm-5.1.0-9.fc33.x86_64

This is the error:

Error starting domain: internal error: process exited while connecting
to monitor: qemu-system-x86_64: /builddir/build/BUILD/qemu-5.1.0/hw/acpi
/bios-linker-loader.c:239: bios_linker_loader_add_checksum: Assertion

I see this were referenced in a patch from some time ago and supposedly
fixed.  Here is the patch info I was able to find:

[Ed Davison]

Hmmm.  Well, I don't know what the command line was.  I use Virtual
Machine Manager (virt-manager.org) for my interface to the VM and it
does the startup.  The error shows up when I start the VM.

In this case you should be able to attach domain xml. (View->Details->Overview->XML)

Also try and see if the following patch helps:

The patch may be a bit beyond me at the moment as I use a package to
install this and would have to figure out how to download source, get it
configure, patched and compiled.  Whew!  Maybe ...

But here is my XML config file.

I don't see anything in this config that could trigger the assert.
(RAM size is 2Kb off 4Gb, but that's probably not the issue)

Can you provide a stack trace, it should help to find out
which path triggers assert.
