Back when the original version of this chunk of code was added (commit 41b087198 in libvirt-0.8.1 in April 2010), we used virExecDaemonize() to start the qemu process, and would continue on in the function (which at that time was called qemudStartVMDaemon()) even if a -1 was returned. So it was possible to get to this code with rv == -1 (it was called "ret" in that version of the code). In modern libvirt code, qemu is started with virCommandRun(); then we call virPidFileReadPath(); those are the only two ways of setting "rv" prior to this code being removed, and in either case if the new value of rv < 0, then we immediately skip over the rest of the code to the cleanup: label. This means that the code being removed by this patch is unreachable. Signed-off-by: Laine Stump <laine@redhat.com> Reviewed-by: Daniel Henrique Barboza <danielhb413@gmail.com>
Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
