From 0e39bb022b5fa8c11964968885f3263c02ce42b0 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Tue, 2 Aug 2016 08:32:32 +0200 Subject: [PATCH] xen: use a common function for pv and hvm guest backend register calls Instead of calling xen_be_register() for each supported backend type for hvm and pv guests in their machine init functions use a common function in order not to have to add new backends twice. This at once fixes the error that hvm domains couldn't use the qusb backend.
