[libvirt] [PATCH v3 02/13] qemu: Differentiate error codes when VM exits in qemuDomainDetectVcpuPids

Some callers will need to behave differently when the detection failed and when the VM crashed during the redetection. Return -2 if it crashed. --- Notes: v3: New in series. v2: fix bugs regarding error codes from redetection src/qemu/qemu_domain.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 7290e3a..c4fa860 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -4292,7 +4292,7 @@ qemuDomainGetVcpuPid(virDomainObjPtr vm, * Updates vCPU thread ids in the private data of @vm. * * Returns number of detected vCPU threads on success, -1 on error and reports - * an appropriate error. + * an appropriate error, -2 if the domain doesn't exist any more. */ int qemuDomainDetectVcpuPids(virQEMUDriverPtr driver, @@ -4339,7 +4339,7 @@ qemuDomainDetectVcpuPids(virQEMUDriverPtr driver, ncpupids = qemuMonitorGetCPUInfo(priv->mon, &cpupids); if (qemuDomainObjExitMonitor(driver, vm) < 0) { VIR_FREE(cpupids); - return -1; + return -2; } /* failure to get the VCPU <-> PID mapping or to execute the query * command will not be treated fatal as some versions of qemu don't -- 2.6.2
