From 91b7c36af5d91f9ddfe47a3a2b1b35368ef171a4 Mon Sep 17 00:00:00 2001 Message-Id: <91b7c36af5d91f9ddfe47a3a2b1b35368ef171a4@dist-git> From: Andrea Bolognani Date: Fri, 5 Apr 2019 10:57:40 +0200 Subject: [PATCH] qemu: Drop QEMU_CAPS_ENABLE_KVM It was already available in 1.5.0. Moreover, we're not even formatting it on the QEMU command line, ever: we just use it as part of some logic that decides whether KVM support should be advertised, and as it turns out that logic is actually buggy and dropping this capability fixes it. https://bugzilla.redhat.com/show_bug.cgi?id=1628469 Signed-off-by: Andrea Bolognani Reviewed-by: Jiri Denemark (cherry picked from commit 88983855d5496a74b97551860db737c2b17b100e) Signed-off-by: Andrea Bolognani Message-Id: <20190405085744.8179-4-abologna@redhat.com> Reviewed-by: Jiri Denemark --- src/qemu/qemu_capabilities.c | 3 --- src/qemu/qemu_capabilities.h | 2 +- tests/qemuxml2argvtest.c | 11 +++++------ 3 files changed, 6 insertions(+), 10 deletions(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 4f2051a2bb..c31c991a6f 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -834,7 +834,6 @@ virQEMUCapsInitGuestFromBinary(virCapsPtr caps, if (virFileExists("/dev/kvm") && (virQEMUCapsGet(qemubinCaps, QEMU_CAPS_KVM) || - virQEMUCapsGet(qemubinCaps, QEMU_CAPS_ENABLE_KVM) || kvmbin)) haskvm = true; @@ -2604,7 +2603,6 @@ virQEMUCapsProbeQMPKVMState(virQEMUCapsPtr qemuCaps, virQEMUCapsClear(qemuCaps, QEMU_CAPS_KVM); } else if (!enabled) { virQEMUCapsClear(qemuCaps, QEMU_CAPS_KVM); - virQEMUCapsSet(qemuCaps, QEMU_CAPS_ENABLE_KVM); } return 0; @@ -3912,7 +3910,6 @@ virQEMUCapsIsValid(void *data, priv->runUid, priv->runGid) == 0; if (!virQEMUCapsGet(qemuCaps, QEMU_CAPS_KVM) && - virQEMUCapsGet(qemuCaps, QEMU_CAPS_ENABLE_KVM) && kvmUsable) { VIR_DEBUG("KVM was not enabled when probing '%s', " "but it should be usable now", diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index 9e8ad5f5c3..98668115d6 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -79,7 +79,7 @@ typedef enum { /* virQEMUCapsFlags grouping marker for syntax-check */ X_QEMU_CAPS_XEN_DOMID, /* -xen-domid */ X_QEMU_CAPS_MIGRATE_QEMU_UNIX, /* qemu migration via unix sockets */ X_QEMU_CAPS_CHARDEV, /* Is the new -chardev arg available */ - QEMU_CAPS_ENABLE_KVM, /* -enable-kvm flag */ + X_QEMU_CAPS_ENABLE_KVM, /* -enable-kvm flag */ X_QEMU_CAPS_MONITOR_JSON, /* JSON mode for monitor */ /* 25 */ diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 7a731e2f40..f401076731 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -912,16 +912,15 @@ mymain(void) DO_TEST("clock-france", NONE); DO_TEST("clock-hpet-off", NONE); DO_TEST("clock-catchup", QEMU_CAPS_KVM_PIT_TICK_POLICY); - DO_TEST("cpu-kvmclock", QEMU_CAPS_ENABLE_KVM); - DO_TEST("cpu-host-kvmclock", QEMU_CAPS_ENABLE_KVM); + DO_TEST("cpu-kvmclock", NONE); + DO_TEST("cpu-host-kvmclock", NONE); DO_TEST("kvmclock", QEMU_CAPS_KVM); DO_TEST("clock-timer-hyperv-rtc", QEMU_CAPS_KVM); - DO_TEST("cpu-eoi-disabled", QEMU_CAPS_ENABLE_KVM); - DO_TEST("cpu-eoi-enabled", QEMU_CAPS_ENABLE_KVM); + DO_TEST("cpu-eoi-disabled", NONE); + DO_TEST("cpu-eoi-enabled", NONE); DO_TEST("controller-order", QEMU_CAPS_KVM, - QEMU_CAPS_ENABLE_KVM, QEMU_CAPS_PIIX3_USB_UHCI, QEMU_CAPS_CCID_PASSTHRU, QEMU_CAPS_SPICE, @@ -933,7 +932,7 @@ mymain(void) DO_TEST("eoi-enabled", NONE); DO_TEST("pv-spinlock-disabled", NONE); DO_TEST("pv-spinlock-enabled", NONE); - DO_TEST("kvmclock+eoi-disabled", QEMU_CAPS_ENABLE_KVM); + DO_TEST("kvmclock+eoi-disabled", NONE); DO_TEST("hyperv", NONE); DO_TEST("hyperv-off", NONE); -- 2.21.0
