Subject: [PATCH 7/8] qemu-options: document -compat insecure-input parameter
Date: Wed, 28 Oct 2026 13:36:02 +0000	[thread overview]
Message-ID: <20261028133603.1893289-8-berrange@redhat.com> (raw)
In-Reply-To: <20261028133603.1893289-1-berrange@redhat.com>

This adds documentation for the previously added 'insecure-input'
parameter to -compat, which controls policy for insecure
configuration requests.
