+Subject: qemu: do not define known no-op features
+
+Qemu dropped cpu features for osxsave and ospke [1][2].
+The reason for the instant removal is that those features were never
+configurable as discussed in [3].
+
+Fortunately the use cases adding those flags in the past are rare, but
+they exist. One that I identified are e.g. older virt-install when used
+with --cpu=host-model and there always could be the case of a user
+adding it to the guest xml.
+
+This triggers an issue like:
+ qemu-system-x86_64: can't apply global Broadwell-noTSX-x86_64-
+ cpu.osxsave=on: Property '.osxsave' not found
+
+Ensure that this does no more break spawning newer qemu versions by
+not rendering those features into the qemu command line.
+
+Fixes: https://bugs.launchpad.net/fedora/+source/qemu/+bug/1825195
