From 3cb9c6553be28b01761c97768abb41c4b5aaa333 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Wed, 18 Oct 2023 16:27:37 -0300 Subject: [PATCH] tests/qtest/migration: Specify the geometry of the bootsector We're about to enable the x86_64 tests to run with the q35 machine, but that machine does not work with the program we use to dirty the memory for the tests. The issue is that QEMU needs to guess the geometry of the "disk" we give to it and the guessed geometry doesn't pass the sanity checks done by SeaBIOS. This causes SeaBIOS to interpret the geometry as if needing a translation from LBA to CHS and SeaBIOS ends up miscomputing the number of cylinders and aborting due to that. The reason things work with the "pc" machine is that is uses ATA instead of AHCI like q35 and SeaBIOS has an exception for ATA that ends up skipping the sanity checks and ignoring translation altogether. Workaround this situation by specifying a geometry in the command line.
