Subject: [PATCH] domain_conf: Use virXMLFormatElement() to format hyperv
features
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Not only is it more modern that old virBufferAsprintf() of
opening and closing tag, it's also aware of child elements buffer
and thus formats a singleton properly.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
Reviewed-by: Ján Tomko <jtomko@redhat.com>
(cherry picked from commit c9716c0e0904c86d7e1c9258bc6e808ba7bc8262)
Additionally, hyperv-passthrough.x86_64-6.1.0.xml was modified
too, since the file doesn't exist upstream anymore (see
v11.2.0-rc1~225), but downstream it does.
Resolves: https://issues.redhat.com/browse/RHEL-122930
