A memory page poisoned from the hypervisor level is no longer readable. The migration of a VM will crash Qemu when it tries to read the memory address space and stumbles on the poisoned page with a similar stack trace: Program terminated with signal SIGBUS, Bus error. #0 _mm256_loadu_si256 #1 buffer_zero_avx2 #2 select_accel_fn #3 buffer_is_zero #4 save_zero_page #5 ram_save_target_page_legacy #6 ram_save_host_page #7 ram_find_and_save_block #8 ram_save_iterate #9 qemu_savevm_state_iterate #10 migration_iteration_run #11 migration_thread #12 qemu_thread_start To avoid this VM crash during the migration, prevent the migration when a known hardware poison exists on the VM.
