That's unfortunate. I'd pulled that from https://wiki.qemu.org/ChangeLog/10.1 but looking through the code I indeed only see SEV enablement, so maybe that changelog entry was out of sync with what actually went upstream. The ship has sailed on the announcement email obviously but I'll fix it up in the blog post at least. -Mike > > With regards, > Daniel > -- > |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| > |: https://libvirt.org -o- https://fstop138.berrange.com :| > |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :| >
