Hi,
> Can you also provide any steps to test vmstate migration ?
Helper script below, run it with something like:
$script -m 4G -vga std \
-cdrom Fedora-Workstation-Live-x86_64-32-1.6.iso \
-device qemu-xhci -device usb-tablet

# master branch / devel branch
dst="/home/kraxel/projects/qemu/build/default/x86_64-softmmu/qemu-system-x86_64"
# time to wait before migration
sec=60
# vmstate storage
tmp="$(mktemp ${TMPDIR-/var/tmp}/vmstate-XXXXXXXXXXXXXX)"
trap "rm -f $tmp" EXIT
# figure machine type to use
machine=$($src -M help | awk '/default/ { print $1 }')
machine="${machine},vmport=off"
machine="${machine},accel=kvm"
