** Description changed:

  There seem to be conditions where old qemu/libvirt created guests with
  the osxsafe feature
  
-     <model fallback='allow'>Broadwell-noTSX</model>
-     <vendor>Intel</vendor>
+     <model fallback='allow'>Broadwell-noTSX</model>
+     <vendor>Intel</vendor>
  ...
-     <feature policy='require' name='osxsave'/>
+     <feature policy='require' name='osxsave'/>
  
  That feature was now removed in recent qemu.
-   => https://bugzilla.redhat.com/show_bug.cgi?id=1644848
+ => https://git.qemu.org/?p=qemu.git;a=commit;h=f1a23522
+ 
  
  But its lack might cause issues starting some old guests using it after 
upgrade.
-   qemu-system-x86_64: can't apply global 
Broadwell-noTSX-x86_64-cpu.osxsave=on: Property '.osxsave' not found
+   qemu-system-x86_64: can't apply global 
Broadwell-noTSX-x86_64-cpu.osxsave=on: Property '.osxsave' not found
+ 
+ Same bug in Fedora:
+  => https://bugzilla.redhat.com/show_bug.cgi?id=1644848
  
  I'd want to analyze omre of the background, why we have it in our IBRS
  type (still it seems) and if we can make modifications to make the
  transition more smooth.
