When attaching a device that already exists, xend driver updates the device with "device_configure", it causes problems (e.g. for disk device, 'device_configure' only can be used to update device like CDROM), on the other hand, we provide additional API (virDomainUpdateDevice) to update device, this fix is to raise up errors instead of updating the existed device which is not CDROM device. Changes from v1 to v2: - allow to update CDROM * src/xen/xend_internal.c
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.
