As we start/shutdown guests, or hotplug/hot-unplug devices, we can add or delete devices as appropriate from a list of active devices. Then, in pciReset(), we can use this to determine whether its safe to reset a device as a side effect of resetting another device. * src/qemu_conf.h: add activePciHostdevs to qemud_driver * src/qemu_driver.c: maintain the activePciHostdevs list, and pass it to pciResetDevice() * src/pci.[ch]: pass the activeDevs list to pciResetDevice() and use it to determine whether a Secondary Bus Reset is safe
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.
