[libvirt] [PATCH v3 2/7] qemu: Introduce qemuProcessLaunch

Once qemuProcessInit was called, qemuProcessLaunch will launch a new QEMU process with stopped virtual CPUs. Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com&gt; --- Notes: ACKed in version 2 Version 3: - no change Version 2: - save status before running VIR_HOOK_QEMU_OP_STARTED hook - call virSecurityManagerSetAllLabel even if !incoming - move qemuProcessStop out of qemuProcessLaunch to avoid it being called twice src/qemu/qemu_process.c | 315 ++++++++++++++++++++++++++++-------------------- src/qemu/qemu_process.h | 9 ++ 2 files changed, 195 insertions(+), 129 deletions(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 83a17ce..1b3cbc0 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -4560,16 +4560,28 @@ qemuProcessInit(virQEMUDriverPtr driver, } -int qemuProcessStart(virConnectPtr conn, - virQEMUDriverPtr driver, - virDomainObjPtr vm, - qemuDomainAsyncJob asyncJob, - const char *migrateFrom, - int migrateFd, - const char *migratePath, - virDomainSnapshotObjPtr snapshot, - virNetDevVPortProfileOp vmop, - unsigned int flags) +/** + * qemuProcessLaunch: + * + * Launch a new QEMU process with stopped virtual CPUs. + * + * The caller is supposed to call qemuProcessStop with appropriate + * flags in case of failure. + * + * Returns 0 on success, + * -1 on error which happened before devices were labeled and thus + * there is no need to restore them, + * -2 on error requesting security labels to be restored. + */ +int +qemuProcessLaunch(virConnectPtr conn, + virQEMUDriverPtr driver, + virDomainObjPtr vm, + qemuDomainAsyncJob asyncJob, + qemuProcessIncomingDefPtr incoming, + virDomainSnapshotObjPtr snapshot, + virNetDevVPortProfileOp vmop, + unsigned int flags) { int ret = -1; int rv; @@ -4581,18 +4593,22 @@ int qemuProcessStart(virConnectPtr conn, struct qemuProcessHookData hookData; size_t i; char *nodeset = NULL; - unsigned int stop_flags; - virQEMUDriverConfigPtr cfg = NULL; + virQEMUDriverConfigPtr cfg; virCapsPtr caps = NULL; unsigned int hostdev_flags = 0; size_t nnicindexes = 0; int *nicindexes = NULL; - qemuProcessIncomingDefPtr incoming = NULL; - VIR_DEBUG("vm=%p name=%s id=%d asyncJob=%d migrateFrom=%s migrateFd=%d " - "migratePath=%s snapshot=%p vmop=%d flags=0x%x", - vm, vm->def->name, vm->def->id, asyncJob, NULLSTR(migrateFrom), - migrateFd, NULLSTR(migratePath), snapshot, vmop, flags); + VIR_DEBUG("vm=%p name=%s id=%d asyncJob=%d " + "incoming.launchURI=%s incoming.deferredURI=%s " + "incoming.fd=%d incoming.path=%s " + "snapshot=%p vmop=%d flags=0x%x", + vm, vm->def->name, vm->def->id, asyncJob, + NULLSTR(incoming ?
