From b8f548e00daaf08ce34c2b8578e5a2b032b082b7 Mon Sep 17 00:00:00 2001 Message-Id: From: Michal Privoznik Date: Mon, 9 Jul 2018 12:07:39 +0200 Subject: [PATCH] qemuDomainDeviceDefValidateNetwork: Check for range only if IP prefix set https://bugzilla.redhat.com/show_bug.cgi?id=1515533 The @prefix attribute to element for interface type user is optional. Therefore, if left out it has value of zero in which case we should not check whether it falls into <4, 27> range. Otherwise we fail parsing domain XML for no good reason. Broken by commit b62b8090b2ad4524a5bf9d40d0d1c17a9d57f5a0.
