We should include maximum physical address size in the CPU definition created by virConnectBaselineHypervisorCPU only if we know the value for all input CPUs. Otherwise we would create a CPU definition that is not usable on all hosts from which we gathered the CPU info. https://issues.redhat.com/browse/RHEL-24850 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com&gt; --- src/qemu/qemu_driver.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 72211da137..72a9542c0b 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -11914,10 +11914,12 @@ qemuConnectBaselineHypervisorCPU(virConnectPtr conn, goto cleanup; for (i = 0; i < ncpus; i++) { - if (!cpus[i]->addr || cpus[i]->addr->limit == 0) + if (!cpus[i]->addr || cpus[i]->addr->limit == 0) { + physAddrSize = 0; continue; + } - if (physAddrSize == 0 || cpus[i]->addr->limit < physAddrSize) + if (i == 0 || cpus[i]->addr->limit < physAddrSize) physAddrSize = cpus[i]->addr->limit; } -- 2.47.0
