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.
