Up until commit 629282d88454, using mode=restrictive caused virNumaSetupMemoryPolicy() to be called from qemuProcessHook(), and that in turn resulted in virNumaNodesetIsAvailable() being called and the nodeset being validated. After that change, the only validation for the nodeset is the one happening in qemuBuildMemoryBackendProps(), which is skipped when using mode=restrictive. Make sure virNumaNodesetIsAvailable() is called whenever a nodeset has been provided by the user, regardless of the mode. https://bugzilla.redhat.com/show_bug.cgi?id=2156289 Signed-off-by: Andrea Bolognani <abologna@xxxxxxxxxx> --- src/qemu/qemu_command.c | 6 ++-- ...unavailable-restrictive.x86_64-latest.args | 32 ------------------- ...-unavailable-restrictive.x86_64-latest.err | 1 + tests/qemuxml2argvtest.c | 2 +- 4 files changed, 6 insertions(+), 35 deletions(-) delete mode 100644 tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.err diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index ee2e873b95..7a2c576e83 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -3428,12 +3428,14 @@ qemuBuildMemoryBackendProps(virJSONValue **backendProps, return -1; } + /* Make sure the requested nodeset is sensible */ + if (nodemask && !virNumaNodesetIsAvailable(nodemask)) + return -1; + /* If mode is "restrictive", we should only use cgroups setting allowed memory * nodes, and skip passing the host-nodes and policy parameters to QEMU command * line which means we will use system default memory policy. */ if (nodemask && mode != VIR_DOMAIN_NUMATUNE_MEM_RESTRICTIVE) { - if (!virNumaNodesetIsAvailable(nodemask)) - return -1; if (virJSONValueObjectAdd(&props, "m:host-nodes", nodemask, "S:policy", qemuNumaPolicyTypeToString(mode), diff --git a/tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.args b/tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.args deleted file mode 100644 index b257ef1c68..0000000000 --- a/tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.args +++ /dev/null @@ -1,32 +0,0 @@ -LC_ALL=C \ -PATH=/bin \ -HOME=/tmp/lib/domain--1-QEMUGuest \ -USER=test \ -LOGNAME=test \ -XDG_DATA_HOME=/tmp/lib/domain--1-QEMUGuest/.local/share \ -XDG_CACHE_HOME=/tmp/lib/domain--1-QEMUGuest/.cache \ -XDG_CONFIG_HOME=/tmp/lib/domain--1-QEMUGuest/.config \ -/usr/bin/qemu-system-x86_64 \ --name guest=QEMUGuest,debug-threads=on \ --S \ --object '{"qom-type":"secret","id":"masterKey0","format":"raw","file":"/tmp/lib/domain--1-QEMUGuest/master-key.aes"}' \ --machine pc,usb=off,dump-guest-core=off,memory-backend=pc.ram \ --accel tcg \ --cpu qemu64 \ --m 24104 \ --object '{"qom-type":"memory-backend-ram","id":"pc.ram","size":25274875904}' \ --overcommit mem-lock=off \ --smp 32,sockets=32,cores=1,threads=1 \ --uuid 9f4b6512-e73a-4a25-93e8-5307802821ce \ --display none \ --no-user-config \ --nodefaults \ --chardev socket,id=charmonitor,fd=1729,server=on,wait=off \ --mon chardev=charmonitor,id=monitor,mode=control \ --rtc base=utc \ --no-shutdown \ --no-acpi \ --boot strict=on \ --audiodev '{"id":"audio1","driver":"none"}' \ --sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \ --msg timestamp=on diff --git a/tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.err b/tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.err new file mode 100644 index 0000000000..a826c3cdeb --- /dev/null +++ b/tests/qemuxml2argvdata/numatune-memnode-unavailable-restrictive.x86_64-latest.err @@ -0,0 +1 @@ +internal error: Mock: no numa node set is available at bit 999 diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 8130e12314..44ad0f7049 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -1982,7 +1982,7 @@ mymain(void) DO_TEST_PARSE_ERROR_NOCAPS("numatune-memnode-nocpu"); DO_TEST_PARSE_ERROR_NOCAPS("numatune-memnodes-problematic"); DO_TEST_CAPS_LATEST_FAILURE("numatune-memnode-unavailable-strict"); - DO_TEST_CAPS_LATEST("numatune-memnode-unavailable-restrictive"); + DO_TEST_CAPS_LATEST_FAILURE("numatune-memnode-unavailable-restrictive"); DO_TEST_NOCAPS("numad"); DO_TEST_NOCAPS("numad-auto-vcpu-static-numatune"); DO_TEST_PARSE_ERROR_NOCAPS("numad-auto-vcpu-static-numatune-no-nodeset"); -- 2.39.0
