Start QEMU with a pci-serial-2x device:
-chardev file,path=/dev/null,id=foo2
-chardev file,path=/dev/null,id=foo3
-device id=gg,driver=pci-serial-2x,chardev1=foo2,chardev2=foo3
Wait until the guest finishes booting (F-19 in my case), then hot unplug
the device:
(qemu) device_del gg
(qemu) qemu-system-x86_64: /work/armbru/tmp/qemu/memory.c:1021:
memory_region_destroy: Assertion `((&mr->subregions)->tqh_first == ((void
*)0))' failed.
Aborted (core dumped)
A missing memory_region_del_subregion. Patch on the way. Paolo
