And adding comments.
<!-- test comment here -->
It won't complain.* But the comment is removed.
*Usually if you make a syntax error (for example add an extra >) somewhere), it says something like this.

Is there any way to preserve comments in virsh / libvirt xml files?
It appears that now you can, copy your xml file somewhere, tell virsh to use it :
virsh define ~/vm.xml
and comment what you want.
When you launch the vm, virsh will make a copy of the file in /etc/libvirt, remove comments there and start the vm, thus not touching your original xml file /etc/libvirt.
Use:
<metadata comment="This is a comment"/>
Tested on CentOS 8 Stream with:
virsh --version
4.5.0
