New tigervnc changes the way to send long pressed key,
from "down up down up ..." to "down down ... up", it only
affects xen pv console mode. I send a patch to latest
kernel side, but it may have a fix in qemu backend for
back compatible becase guest VMs may use very old kernel.
This patch inserts an up event after each regular key down
event to simulate an auto-repeat key event for xen keyboard
frontend driver.
