From 574ee06de9c4fe63c90be90dc9c747fc9382bb2b Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Thu, 24 Aug 2017 12:08:48 +0200 Subject: [PATCH] s390x/s390-skeys: Mark the storage key devices with user_creatable = false QEMU currently aborts if the user tries to create a skey device: $ s390x-softmmu/qemu-system-s390x -nographic -device s390-skeys-qemu qemu-system-s390x: hw/s390x/s390-skeys.c:30: s390_get_skeys_device: Assertion `ss' failed. Aborted (core dumped) The storage key devices are only meant to be instantiated one time, internally. They can not be used by the user, so mark them with user_creatable = false.
