From baf64ed57de359bb093c9557108edcab6f77dfb9 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Sat, 2 Nov 2013 15:05:07 +0100 Subject: rhel: Make "isa-cirrus-vga" device unavailable RH-Author: Markus Armbruster Message-id: <1383404707-6015-3-git-send-email-armbru@redhat.com> Patchwork-id: 55270 O-Subject: [PATCH 7.0 qemu-kvm 2/2] rhel: Make "isa-cirrus-vga" device unavailable Bugzilla: 1001088 RH-Acked-by: Paolo Bonzini RH-Acked-by: Marcel Apfelbaum RH-Acked-by: Alex Williamson From: Markus Armbruster We can't drop it, because the ISA device is entangled with the PCI device, which we want to keep. Disentangling it upstream would be nice, but we're out of time. Instead, make it unavailable with -device / device_add. Suffices, because the only other way to get it is via pc_vga_init() calling isa_vga_init(), which it never does in RHEL, because it never gets a null pci_bus argument.
