[libvirt] [PATCHv2] Fix explicit usage of default video PCI slots
by Ján Tomko 06 Jan '14

06 Jan '14

Do not leave the PCI address of the primary video card set to the legacy default (0000:00:02.0) if we're doing two-pass allocation. Since QEMU 1.6 (QEMU_CAPS_VIDEO_PRIMARY) we allow the primary video card to be on other slots than 0000:00:02.0 (as we use -device instead of -vga). However we fail to assign it an address if: * another device explicitly uses 0000:00:02.0 and * the primary video device has no address specified On the first pass, we have set the address to default, then checked if it's available, leaving it set even if it wasn't. This address got picked up by the second pass, resulting in a conflict: XML error: Attempted double use of PCI slot 0000:00:02.0 (may need "multifunction='on'" for device on function 0) Also fix the test that was supposed to catch this. --- v1: https://www.redhat.com/archives/libvir-list/2013-December/msg01125.html v2: no functional change rewrote the commit message to mention that this only happens with QEMU 1.6 and (hopefully) explain what 'this' is more clearly src/qemu/qemu_command.c | 50 +++++++++++++++++++++--------------------------- tests/qemuxml2argvtest.c | 3 ++- 2 files changed, 24 insertions(+), 29 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index d723dc8..2a64cd1 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -2379,7 +2379,6 @@ qemuValidateDevicePCISlotsPIIX3(virDomainDefPtr def, size_t i;
