This is also a bug fix - on the error path, qemu_hotplug would leave the configfd file leaked into qemu. At least the next attempt to hotplug a PCI device would reuse the same fdname, and when the qemu getfd monitor command gets a new fd by the same name as an earlier one, it closes the earlier one, so there is no risk of qemu running out of fds. * src/qemu/qemu_monitor.h (qemuMonitorAddDeviceWithFd): New prototype. * src/qemu/qemu_monitor.c (qemuMonitorAddDevice): Move guts... (qemuMonitorAddDeviceWithFd): ...to new function, and add support for fd passing. * src/qemu/qemu_hotplug.c (qemuDomainAttachHostPciDevice): Use it to simplify code. Suggested by Daniel P. Berrange.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
