I am almost (99%) sure that QEMU will complain about a bad arg.
gdb says:
(gdb) r
Starting program:
/home/don/qemu/out/master/x86_64-softmmu/qemu-system-x86_64 -M pc
-machine accel=xen,vmportport=1
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
qemu-system-x86_64: -machine accel=xen,vmportport=1: Invalid parameter
'vmportport'
In which case domU will fail to start.
