From 0f5958f5c5530d0cc25081f09f7c5be565c09ff5 Mon Sep 17 00:00:00 2001 From: Cole Robinson Date: Thu, 17 Jan 2019 12:52:39 -0500 Subject: [PATCH] qemu: Support memballoon model=virtio-{non-}transitional Add new model values for virtio transitional devices. Ex: * "virtio-transitional" maps to qemu "virtio-balloon-pci-transitional" * "virtio-non-transitional" maps to qemu "virtio-balloon-pci-non-transitional" Reviewed-by: Andrea Bolognani Signed-off-by: Cole Robinson --- docs/formatdomain.html.in | 4 ++++ docs/schemas/domaincommon.rng | 2 ++ src/conf/domain_conf.c | 2 ++ src/conf/domain_conf.h | 2 ++ src/libxl/libxl_conf.c | 2 ++ src/qemu/qemu_command.c | 6 +++++- src/qemu/qemu_domain.c | 4 +++- src/qemu/qemu_domain_address.c | 4 ++++ .../virtio-non-transitional.x86_64-3.1.0.args | 5 ++++- .../virtio-non-transitional.x86_64-latest.args | 4 +++- tests/qemuxml2argvdata/virtio-non-transitional.xml | 2 +- .../virtio-transitional.x86_64-3.1.0.args | 4 +++- .../virtio-transitional.x86_64-latest.args | 3 ++- tests/qemuxml2argvdata/virtio-transitional.xml | 2 +- tests/qemuxml2xmloutdata/virtio-non-transitional.xml | 11 +++++++++-- tests/qemuxml2xmloutdata/virtio-transitional.xml | 6 ++++-- 16 files changed, 51 insertions(+), 12 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 4853662939..0740d2529e 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -7959,8 +7959,12 @@ qemu-kvm -net nic,model=? /dev/null
