Hi :
I see a commit in qemu that adds support for CLZERO but in CPUIDs. :
commit e900135dcfb676a4019dc206395e02db5d1de0d6
Author: Sebastian Andrzej Siewior <bige...@linutronix.de>
Date: Wed Sep 25 23:49:48 2019 +0200
i386: Add CPUID bit for CLZERO and XSAVEERPTR
The CPUID bits CLZERO and XSAVEERPTR are availble on AMD's ZEN platform
and could be passed to the guest.

Is there a corresponding change in libvirt adding this capability? Libvirt
complains when I add it manually in the vm xml:
# virsh create newvm.xml
error: Failed to create domain from newvm.xml
error: unsupported configuration: unknown CPU feature: clzero
# grep clzero newvm.xml
<feature policy='require' name='clzero'/>
Should we add it?
thanks
ani
