When the guest shuts down, we should attempt to restore all PCI host devices to a sane state. In the case of managed hostdevs, we should reset and re-attach the devices. In the case of unmanaged hostdevs, we should just reset them. Note, KVM will already reset assigned devices when the guest shuts down using whatever means it can, so we are only doing it to cover the cases the kernel can't handle. * src/qemu_driver.c: add qemuDomainReAttachHostDevices() and call it from qemudShutdownVMDaemon()
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.
