[libvirt] [PATCH 14/34] qemu: domain: Prepare qemuDomainDetectVcpuPids for reuse

Free the old vcpupids array in case when this function is called again during the run of the VM. It will be later reused in the vCPU hotplug code. --- src/qemu/qemu_domain.c | 17 +++++++---------- 1 file changed, 7 insertions(+), 10 deletions(-) diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 1ea1cd3..a6fb232 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -4275,7 +4275,7 @@ qemuDomainDetectVcpuPids(virQEMUDriverPtr driver, int asyncJob) { pid_t *cpupids = NULL; - int ncpupids; + int ncpupids = 0; qemuDomainObjPrivatePtr priv = vm->privateData; /* @@ -4306,11 +4306,8 @@ qemuDomainDetectVcpuPids(virQEMUDriverPtr driver, * Just disable CPU pinning with TCG until someone wants * to try to do this hard work. */ - if (vm->def->virtType == VIR_DOMAIN_VIRT_QEMU) { - priv->nvcpupids = 0; - priv->vcpupids = NULL; - return 0; - } + if (vm->def->virtType == VIR_DOMAIN_VIRT_QEMU) + goto done; if (qemuDomainObjEnterMonitorAsync(driver, vm, asyncJob) < 0) return -1; @@ -4322,10 +4319,8 @@ qemuDomainDetectVcpuPids(virQEMUDriverPtr driver, * support this command */ if (ncpupids <= 0) { virResetLastError(); - - priv->nvcpupids = 0; - priv->vcpupids = NULL; - return 0; + ncpupids = 0; + goto done; } if (ncpupids != virDomainDefGetVcpus(vm->def)) { @@ -4337,6 +4332,8 @@ qemuDomainDetectVcpuPids(virQEMUDriverPtr driver, return -1; } + done: + VIR_FREE(priv->vcpupids); priv->nvcpupids = ncpupids; priv->vcpupids = cpupids; return 0; -- 2.6.2
