Re: [libvirt] [PATCH v2 05/31] qemu: Enable KVM when probing capabilities

CPU related capabilities may differ depending on accelerator used when probing. Let's use KVM if available when probing QEMU and fall back to TCG. The created capabilities already contain all we need to distinguish whether KVM or TCG was used: - KVM was used when probing capabilities: QEMU_CAPS_KVM is set QEMU_CAPS_ENABLE_KVM is not set - TCG was used and QEMU supports KVM, but it failed (e.g., missing kernel module or wrong /dev/kvm permissions) QEMU_CAPS_KVM is not set QEMU_CAPS_ENABLE_KVM is set - KVM was not used and QEMU does not support it QEMU_CAPS_KVM is not set QEMU_CAPS_ENABLE_KVM is not set Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com&gt; --- src/qemu/qemu_capabilities.c | 45 +++++++++++++++++++++++++++++++++++++++++--- src/qemu/qemu_capabilities.h | 3 --- src/qemu/qemu_capspriv.h | 8 ++++++++ tests/qemucapabilitiestest.c | 5 +++++ 4 files changed, 55 insertions(+), 6 deletions(-)
