One of our latest USB device handling patches 05abd1507d66aabb6cad12eeafeb4c4d1911c585 introduced a regression. That is, we first create a temporary list of all USB devices that are to be used by domain just starting up. Then we iterate over and check if a device from the list is in the global list of currently assigned devices (activeUsbHostdevs). If not, we add it there and continue with next iteration then. But if a device from temporary list is either taken already or adding to the activeUsbHostdevs fails, we remove all devices in temp list from the activeUsbHostdevs list. Therefore, if a device is already taken we remove it from activeUsbHostdevs even if we should not. Thus, next time we allow the device to be assigned to another domain. (cherry picked from commit 2f5fdc886ec7ed8b871ebd0576271f8ee5be1f71)
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.
