Subject: qemu crashes on changing display resolution within guest
Date: Fri, 12 Mar 2021 23:39:49 +0100	[thread overview]
Message-ID: <20210312233949.3681b75d@redhat.com> (raw)

happens on current master,

to reproduce start
./x86_64-softmmu/qemu-system-x86_64 -enable-kvm -m 1g -M pc -vnc localhost:0 \
     -snapshot -cdrom Fedora-Workstation-Live-x86_64-33-1.2.iso

connect to guest using 'Remote Desktop', wait till it boots to graphical desktop
then try to change resolution to 800x600

QEMU will crash in a second or 2 with:
qemu-system-x86_64: ../qemu/accel/kvm/kvm-all.c:690: kvm_log_clear_one_slot: Assertion `QEMU_IS_ALIGNED(start | size, psize)' failed.


offending commit:

Author: Keqian Zhu <zhukeqian1@huawei.com>
Date:   Thu Dec 17 09:49:41 2020 +0800

    accel: kvm: Add aligment assert for kvm_log_clear_one_slot
