From 82ed3155fe72a7e15ab28f86a3c1eb970a92d2f6 Mon Sep 17 00:00:00 2001 From: Manuel Bouyer Date: Tue, 26 Jan 2021 23:47:49 +0100 Subject: [PATCH] NetBSD hotplug: fix block unconfigure on destroy MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When a domain is destroyed, xparams may not be available any more when the block script is called to unconfigure the vnd. Check xparam only at configure time, and just unconfigure any vnd present in the xenstore.
