Careful, note the last sentence in the 0x20 flag description:
Forces this unit to be the console (unless there is
another higher priority console), regardless of the -h
option discussed below. The flag 0x20 must be used
together with the 0x10 flag.
i.e. to use 0x20 you have to set it to 0x30

Never tried, could be a qemu-specific issue?
